AutoMapper also supports profiles I recommend you to use AutoMapper. Kenci. AutoMapper 4. To make sure the the automapper does the right mapping and doesn't returns an exception we must resolve the mapping in details. Profile Instances ¶ A good way to organize your mapping configurations is with profiles. AddProfile(new AutoMapperProfile()) then AutoMapper will respect the [SourceMember] decorators, but not honor the ignore null Conditions in the Profile. public static class Mapping { private static readonly Lazy<IMapper> Lazy = I am using AutoMapper in a . Any number of profiles can be created, and added to one or more One “feature” of AutoMapper allowed you to modify configuration at runtime. 2 Using AutoMapper 8 ProjectTo on DI instance. The setting can be applied globally and can be overridden per profile and per member with AllowNull and DoNotAllowNull. NET, LINQ, SQL Server, MYSQL, Oracle, ASP. 0 Handling Dependency in Automapper Profile. Please find an example of what I'm after: public class Destination { public int Id { get; set; } Following on from Eugene Gorbovoy's answer, if you're using profiles to configure your AutoMapper, you need to use a TypeConverter. ConvertUsing(new CustomerMappingProfile());; } } Just create separate map for each type and automapper will work out which map to use if your type has inner complex I have the following mapping profile public class DomainProfile : Profile { private FootballPredictionsContext m_Context; public DomainProfile(FootballPredictionsContext context) { I have two classes and map one to other with Automapper. NET 6. For ProjectTo, you need to inspect IQueryable. Register AutoMapper in Additionally, when I setup my maps in an AutoMapper. But we need to make sure the business logic gets unit tested. x, add the AutoMapper Dependency Injection Package to your solution via NuGet. And there it simply forwards to the corresponding NuGet package and an article that describes how it searches through the current application domain for all the open types and profiles to load them. NET application, and comparing it with manual mapping. If you don’t like this approach, you can combine AutoMapper’s approach with custom value resolvers if needed. AutoMapper supports polymorphic arrays and collections, such that derived source/destination types are used if found. Value converters are scoped to a single map, and receive the source and destination objects to resolve to a value to map to the destination My problem now is we need to do it with DependencyInjection, so I created the following profiles: Main: public class MainProfile : AutoMapper. For instance: public class Source { // IdName is a simple class containing two fields: Id (int) and Name (string) public IdName Type { get; set; } public int TypeId {get; set; } // another members } public class Destination { // IdNameDest is a simple class such as IdName public IdNameDest Type { get; var mapper = new MapperConfiguration(cfg => cfg. This is by design. AutoMapper in Web API Implementation Step by Step Create the Web API using . Your RegistrationMapping class and others have to be inherited from AutoMapper. Mapper. NET 6, you can use the built-in dependency injection (DI) container along with AutoMapper to set up mapping profiles. Collection. Contribute to AutoMapper/AutoMapper development by creating an account on GitHub. Add, map to, and delete items in a collection by comparing items for matches. In your classes you then have to simply inject an IMapper imapper into And then you let AutoMapper know in what assemblies are those profiles defined by calling the IServiceCollection extension method AddAutoMapper at startup: Profile {public SomeProfile {var map = CreateMap < MySourceType, MyDestinationType >(); map. Configure(); AutoMapper is geared towards model projection scenarios to flatten complex object models to DTOs and other simple objects, whose design is better suited for serialization, communication, AutoMapper is a library designed for object-to-object mapping based on specifications and rules. Automapper Expression mapping one property to many. When I use ProjectTo for mapping data from database to class, second paramter after _mapper. 1 as a mapper in my ASP. One overload allows you to pass each assembly as Just create Profile and all properties which have the same name will mapped automatically. BUT if I comment out c. Member How to use generic Profile with Automapper and Asp. NET Core – Getting Started; Define the Automapper Profile with service Dependency Injection. ForMember() after Mapper. As you can see, this class extends Profile from AutoMapper namespace. This is typically when one type looks nothing like the other, a conversion function already exists, and you would like to go from a “looser” type to a stronger type, such as a source type of string to a destination type of Int32. MappingProfile. User, UsersDetailsViewModel>(); there is a fluent syntax to define the more complicated mappings: And I created Mapping profile. Bot we cannot find any documentation how to access this dictionary in the AutoMapper profile. Map. NET MVC website to map my database objects to ViewModel objects and I am trying to use several profiles to map the same types, but using another logic. NET MVC, ASP. ShouldMapProperty = p => p. AutoMapper is geared towards model projection scenarios to flatten complex object models to DTOs and other simple objects, whose design is better suited for serialization, communication, messaging, or simply an anti-corruption layer between the domain and AutoMapper will ignore null reference exceptions when mapping your source to your target. When you start thinking about using dependency injection (constructor injection in this case), you might want to rethink your I ran into this as well in AutoMapper 11. NET. Create an AutoMapper Profile: Create a MappingProfile class inheriting from Profile to configure the mappings between models and DTOs using CreateMap. The final solution is that, first of all mapping data from database then, for mapping data to output model, we can assign value to ResolutionContext to pass value to A customer of mine was wondering the same thing as DownChapel and his answer triggered me in writing some sample application. Profile { [Dependency] internal AttributeMapper AttributeMapper { get; set; } <--This is not resolved public MainProfile() { The root cause of your issue is the incorrect usage of the AddAutoMapper extension method. DependencyInjection; AutoMapper; Create the classes to Trying to determine the best way to write an automapper profile to map between two objects into lists but the number of items in the destination list will be equal to the number of items in an internal list on the source object. Always put common simple Dependency Injection Examples ASP. Profiles permit the programmer to organize maps into classes, enhancing code readability and maintainability. You can get to the mapper using the overload of ResolveUsing that accepts a delegate with four parameters, the last of which is ResolutionContext that has a Mapper Profiles are one of the best way of organizing all your mapping configurations in one place. As long as you derive from Profile class, the AutoMapper package for . To use AutoMapper for data mapping, create a custom class that inherits from the Profile class. Once you have your types, and a reference to AutoMapper, you can create a map for the two types. This article provides a detailed step-by-step guide on setting up AutoMapper, using it in a . I need to ignore some members mapped inside these profiles at runtime for one of the mapper instances. What I've done is the following. 0 and up. 2 not ignoring properties in profile. AddProfile<MyProfile>()); } } Now, We have completed the AutoMapper configuration parts. There is a NuGet package to be used with the default injection mechanism described here and used in this project. AddProfile<MyProfile>()); } } Create an AutoMapper Profile: Create a MappingProfile class inheriting from Profile to configure the mappings between models and DTOs using CreateMap. And then you let AutoMapper know in what assemblies are those AutoMapper uses a convention-based matching algorithm to match up source to destination values. . ForMember (d => d. Custom Type Converters . You should load certain assembly with profile classes and also register them as Profile. You create separate mapping Profiles that handle creating the Mappings for objects in that Project/Assembly. I recommend you to use AutoMapper. Before I had configuration as below: var config = new MapperConfiguration (cfg I recommend you to use AutoMapper. ProjectTo(). DependencyInjection 3. using AutoMapper; public class MappingProfile : Profile { public MappingProfile() { CreateMap<Person, PersonDTO>(); CreateMap<PersonDTO, Person>(); } } Step 4. CreateMap In this case I would just write a custom mapper. Bar"] = 42}); result. asked Aug 28, 2020 at First of all, Automapper supports mapping of collections. 0 AutoMapper doesn't work in asp net core 5. However, do note:: This AutoMapper will ignore null reference exceptions when mapping your source to your target. This is a good example of why automapper doesn't map As of AutoMapper 8. How to use generic Profile with Automapper and Asp. To handle this, you can inject these services into your Profile Learn to integrate AutoMapper in . This is the file you call from AutofacConfig. How can I achieve such feat using AutoMapper or is it even considered a good practice for AutoMapper? I currently have the following mapping: Mapper. Net Core 3. First add AutoMapper. NET Web API, EF, EF Core, ADO. SO my class looks like following: public class MyClass : Profile { public MyClass { //somemapping here } } You will notice that because the mapped object is a OnlineOrder, AutoMapper has seen you have a more specific mapping for OnlineOrder than OrderDto, and automatically chosen that. ABP模板中，应用层的Module类有一个Initialize方法，该方法中用反射找到所有继承于Profile的类，并添加到映射配置。 I have PagedList implementation and I am trying to use AutoMapper in order to map entity PagedList to DTO PagedList. In your example the foreach loop didn't perform any iterations, because container didn't contain any registrations for Profile. By flattening our model, we create a more simplified object that won’t require a lot of navigation to get at data. 1; AutoMapper. [Pre-v13. MapperCOnfiguration and instead of call AddProfiles you can use the CreateMap method for each profile you want register. I have a class like the following which create a PagedList object and also uses AutoMappper to map types from source to destination. Net MVC projects, is by using AutoMapper Profiles. entity-framework-core; automapper; Share. Is there a good example project that shows how to have different profiles for each project? The most curious thing here is this, the second problem- if I comment out c. Strap on your coding cap, and let’s dive in. But as with above code only ProfileA's mappers will be applied. Map < Foo > (new Dictionary < string, object > {["InnerFoo. AutoMapper profiles don't support async methods in the MapFrom expression. For example: public class UserProfile : Profile { private readonly IUserManager _userManager; public UserProfile(IUserManager userManager) { _userManager = userManager; CreateMap<User, UserViewModel>() Within the documenation is described on how to use AutoMapper with the Microsoft DI framework. public class I am using AutoMapper in my ASP. You then add the profiles to the overall configuration manually, or you can use Reflection/Assembly scanning to automatically load the profiles. However, for some reason, I need to call some service and in order to call that service, I need to call inject that service in Profile class. In the following code I am able to add UserAuthenticationMapper profile to the automapper, but unable to add CustomerDataMapper profile. First retrieve all Profile types from the asseblies and register them in the IoC container (I'm using Autofac). Here you need to create a class that inherits from the class Profile then please add your configuration of mapping into the Constructor. AutoMapper uses a convention-based matching algorithm to match up source to destination values. I need to use a service layer in the AutoMapper profile class in ASP. The reason is that the profileName you pass is the one used by default by AutoMapper as we can see here. Look at this example: You can absolutely do exactly what you want using a custom ITypeConverter<TSource, TDestination> implementation. I generated these two profiles and injected them into the service. Telling injected automapper to use specific mapping profile in map function. EF to support Equality by Primary Keys Its depends on your architecture design. DependencyInjection package to your project. NetCore will sniff all the assemblies and add your profiles so that they are available through the IMapper injection – Similarly you can map straight from Dictionary<string, object> to objects, AutoMapper will line up the keys with property names. Assembly Scanning for auto configuration Profiles can be added to the main mapper configuration in a number of ways, either directly: A convention-based object-object mapper in . Profiles can be added to the main mapper configuration in a number of ways, either directly: or by automatically scanning for profiles: AutoMapper will scan the designated assemblies for How would I be able to use [reuse] an Automapper profile class like the following to create an instance of a mapper? protected override void Configure() base. Below is how you can unit test the AutoMapper profiles, you will need to make sure you My problem has been solved. I'm using AutoMapper 12 and the accepted answer didn't work for me, because I can't access a Mapper when configuring a Profile. You can get to the mapper using the overload of ResolveUsing that accepts a delegate with four parameters, the last of which is ResolutionContext that has a Mapper Value transformers apply an additional transformation to a single type. 1 still applies, except that ResolveUsing has been renamed to MapFrom; the delegate signature remains the same. Before assigning the value, AutoMapper will check to see if the value to be set has any value transformations associated, and will apply them before setting. To handle this, you can inject these services into Even though the maps are on same source and destination type I want the separation by creating a base Profile then inheriting and creating more specific Profiles. Example. /// <summary AutoMapper is a simple C# library that transforms one object type to another object type, which means, it’s a mapper between two objects. Async extension methods for ProjectTo. 0 How do I inject the AutoMapper Configuration in my Service model On automapper where you create the Map you can specify additional processes for specific members of the destination type. Here is a sample implementation, Step 3- Automapper profile dependency injection- IMapper into the module Additionally, when I setup my maps in an AutoMapper. AutoMapper is especially You can create a new AutoMapper. See this SO Question about mapping from the view model back to the domain. AutoMapper allows profiles to be loaded by passing the assembly, the assembly name, or type contained in the assembly. NET Core¶. public class NumberConverter : ITypeConverter<DTO, NumberBase> { public NumberBase Convert(DTO source, NumberBase destination, ResolutionContext context) Configuration inside a profile only applies to maps inside the profile. Profile. Configuration applied to the root configuration applies to all maps created. Converter. asked Apr 21, 2016 at 21:12. ForMember(dest. map I get AutoMapper. And install the following nugets: AutoMapper. I have searched on Stack Overflow and googled about it but I haven't been able to find any help or suggestion on this. In this guide, you’ll explore the intricate world of AutoMapper, delve into its usage, and unravel potential hiccups along the way. Map methods, and if Models - DTO and Automapper profiles (library) Data - EF layer (library) In Web API, I've injected the required interface and concrete class in the startup along with initializing AutoMapper and also referenced the Models project. What C# – Unit testing a AutoMapper Profile mappings. Configure Automapper Profile Class with Parameter Constructor and Ninject. AddMaps method is called immediately during construction of the MapperConfiguration instance (per AutoMapper v11. Microsoft. Here is a sample implementation, Step 3- Automapper profile dependency injection- IMapper into the module AutoMapper is simple library that takes care of Object-to-Object mappings which is otherwise boring & redundant to code every-time. public class MappingProfile : Profile { public MappingProfile() { CreateMap<Rewards, RewardsDTO>(); CreateMap<Customer Just create separate map for each type and automapper will work out which map to use if your type has inner complex types. Code Issues Pull requests Featuring authentication, authorization, logging, global exception-handling. When you use AutoMapper to map our objects, and AutoMapper profiles are the way we do it, it encapsulates a lot of business logic in some cases. NET Core but when I inject service in the constructor it does not work. For instance: public class Source { // IdName is a simple class containing two fields: Id (int) and Name (string) public IdName Type { get; set; } public int TypeId {get; set; } // another members } public class Destination { // IdNameDest is a simple class such as IdName public IdNameDest Type { get; Although there are a bunch of ways to configure profiles, it seems that the only way what I could get it to work was as follows: public class ExampleProfile : Profile { protected override void Configure() { ReplaceMemberName("Z", "A"); CreateMap<Source, Destination>(); // Notice this is CreateMap, NOT Mapper. Profile and then subsequently injected IMapper, I got this exception "Mapper not initialized. Benjamin Abt. cs With AutoMapper you only need to update a single place and can write unit tests to validate this mapping. CreateMap<Journal, JournalDto>(); Now, Journal contains a member named RefTypeID, which corresponding value exists in another table in the database; to look up this value, I have a service which handles a simple int -> string request. 2. How? As we have different Objects, we need to tell automapper which objects and fields are mapped and from where, using the method ForMember and MapFrom. Create Model Classes and AutoMapper Profile. 6. The final solution is that, first of all mapping data from database then, for mapping data to output model, we can assign value to ResolutionContext to pass value to AutoMapper. Collection: Map collections by means of equivalency. Automapper is only useful if you have lots of columns that are all the same name and type (or able to have types mapped consistently between types). public class MapperProfile: Profile { public MapperProfile() { CreateMap<B, C>(); CreateMap<A, C>(); } } When mapping from A to C, I would like to overwrite C's Id with A's IdA while everything else in Data to populate the other properties in C which is effectively the mapping defined with CreateMap<B, C>(). Follow edited Apr 21, 2016 at 21:23. Extensions. To create a mapping you should use profile itself instead of static Mapper class. AutoMapper Inherit Profile Maps. CreateMap<User, UserDto>()). AddMaps(typeof(TargetClass)) AutoMapper will respect the ignore null Conditions in the In . Automapper Profile with service Dependency Injection can be defined as below. However, properties which do not have the same names, they should have custom mapping: public class FromModelToDto : Profile { public FromModelToDto () { CreateMap<CompanyEmployee, EmployeeDto>() . Built with DTOs, repositories, AutoMapper, pagination, JWT, Serilog. Configure Automapper in ASP. public class PagedList<TSrc, TDest> { protected readonly List<TDest> _items = new List<TDest>(); public What about isolating your mapping in its own class. public class MappingProfile : Profile { public MappingProfile() { CreateMap<Rewards, RewardsDTO>(); CreateMap<Customer, CustomerDTO>(). ; In the Convert method of your customer type converter, you can recover your parameter(s) from the I am working on a project where we have AutoMapper Profile class which has all the mappings. x] If using AutoMapper prior to v13. json file). AutoMapper is geared towards model projection scenarios to flatten complex object models to DTOs and other simple objects, whose design is better suited for serialization, communication, messaging, or simply an anti-corruption layer between the domain and AutoMapper is a tool that simplifies this mapping process by automatically mapping similar properties between objects. Net Core and the AutoMapper. Map methods, and if Profiles are one of the best way of organizing all your mapping configurations in one place. 7. On AutoMapper 12 you no longer appear to be able to get information on the maps or profiles from IMapper or from IConfigurationProvider without using reflection. This is the actual configuration for AutoMapperProfile we did above. EqualityComparision between 2 classes. PropertyThatDependsOnIoc, opt => opt. In Automapper 5. Whats wrong I am doing here? ForAllOtherMembers extension method was removed from Automapper 11 I use it to ignore conventional mappings for properties other than the one mentioned before like this ForAllOtherMembers(opt I also tried some other solutions to find the map for the given profile and change the property map to ignore for unmapped property I suggest that you shouldn't mock IMapper: it should behave the same in all circumstances: (unit-test, integration-test, and normal running) - and AutoMapper supports DI anyway. This is because AutoMapper is designed to be a synchronous library that performs mapping operations in memory. For example, using AutoMapper to reduce and standardize code, such as persisting DB data and That’s where AutoMapper comes in. (I suggest you taking a look at its sources to understand what's going on exactly under AutoMapper is a simple C# library that transforms one object type to another object type, which means, it’s a mapper between two objects. Call Initialize with appropriate configuration. None); } } Configuration inside a profile only applies to maps inside the profile. Profile Instances ¶ A good way to To instruct AutoMapper to recognize members with other visibilities, override the default filters ShouldMapField and/or ShouldMapProperty : var configuration = new MapperConfiguration (cfg => {// map properties with public or internal getters cfg. 5 adding profiles to automapper after initialisation. ' Here my Startup. NET Core . And I created Mapping profile. Be sure to remove all such code before release. AutoMapper can handle mapping properties A. I had the idea of doing so by reading Matt's blog post where he says: The really key part is the AutoMapper configuration profile. InnerFoo. NET Core apps. public class UserProfile: Profile { public UserProfile() { CreateMap<User, UserDto>(MemberList. If you are trying to use mapper instances through a container or otherwise, make sure you do not have any calls to the static Mapper. ; In the Convert method of your customer type converter, you can recover your parameter(s) from the After digging around in the IMapper interface (and thanks to the documentation link provided by @LucianBargaoanu), I found exactly what I needed. How to pass parameters to an AutoMapper Profile constructor aka Dependency Injection for AutoMapper While using AutoMapper for mapping different objects in your application, you might encounter situations where you need business logic from other services during the mapping process. If you're only interested in a few columns out of How to pass parameters to an AutoMapper Profile constructor aka Dependency Injection for AutoMapper While using AutoMapper for mapping different objects in your application, you might encounter situations where you need business logic from other services during the mapping process. How can I initialize the AutoMapper profile properly with Unity, so that I can use the mapper anywhere through DI? c#; unity-container; automapper; Share. Because the mapping from source to destination is convention-based, you will still need to test your configuration. DependencyInjection. . Learn automapper - Basic Profile. To instruct AutoMapper to recognize members with other visibilities, override the default filters ShouldMapField and/or ShouldMapProperty : var configuration = new MapperConfiguration (cfg => {// map properties with public or internal getters cfg AutoMapper 6. 0, AddAutoMapper is part of the core package and the DI package is discontinued. You define the configuration using profiles. It seems that if assembly scanning is enabled for the assembly that contains the Profile derived class that does not have a No-Args constructor, that AutoMapper tries to instantiate it even with an explicit registration. If you are using Asp. That caused many problems, so the new API does not allow you to do this. TrimStringValueConverter>(); CreateMap<TestModel, TestEntity>( . Sometimes, you need to take complete control over the conversion of one type to another. The next step is to create a custom file and inherit it with the Profile class provided by AutoMapper. Assembly Scanning for auto configuration Profiles can be added to the main mapper configuration in a number of ways, either directly: As of AutoMapper 8. 5. This works fine on most occasions and is the recommended approach, to my knowledge. netcore automapper automapper-profiles Updated May 14, 2023; C#; csant26 / NZ_Walks_Web_API Star 0. 0 and above and if you are using Profile to create mapper: public class OrderMapper : Profile { public OrderMapper() { CreateMap<Order, OrderDto I want to register all the Mappings in my Business Layer to Data Layer, and Data Layer to Business Layer classes just as my Business Layer assembly loads. DependencyInjection; AutoMapper; Create the classes to Looks like here is a combination of several issues. 1. Also for testing I would like to run the ApplicationCore without the MVC or API projects. Then create an IMappingAction class like this:. Pranaya Rout has very good experience with Microsoft Technologies, Including C#, VB, ASP. Initialize at once ;). AutoMapper also supports Flattening, which can get rid of all those pesky null reference exceptions you might encounter along the way. I use AutoMapper V. AutoMapper is geared towards model projection scenarios to flatten complex object models to DTOs and other simple objects, whose design is better suited for serialization, communication, messaging, or simply an anti-corruption layer between the domain and About the Author: Pranaya Rout Pranaya Rout has published more than 3,000 articles in his 11-year career. Maybe there is a way to register the Profile in dependency injection, but with my limited knowledge of the framework, I couldn't find a clue By default, this will scan the assembly where it is called from. For mapping to destination child objects, you can use the dot notation. With AutoMapper you only need to update a single place and can write unit tests to validate this mapping. AddAutoMapper(); With this line I can convert view models to DTO (and backwards) But I need register profiles located on Services layer to convert DTO to Domain entities (and backwards) Evidently, Automapper not found this profiles. DependencyInjection package, this is also a good way of using Dependency Injection. If you register your profiles with DI like I do, and you just So based on Bruno's answer here and John Skeet's post about singletons I came up with the following solution to have this run only once and be completely isolated in class library unlike the accepted answer which relies on the consumer of the library to configure the mappings in the parent project:. DependencyInjection 11. I know I'm supposed to be using . Here is my interface: public interface IPagedList&lt;T&gt; : IList&lt;T&gt; { The AddAutoMapperApi() extension is responsible for registering the AutoMapper dependency injection into the solution, requiring a type of object from the project that contains the mapping profile I can't find a way to pass any information from my ApplicationService to the AutoMapper Profile, as IObjectMapper. Profile { protected override void Configure() { //ReplaceMemberName("Z", "A"); //CreateMap<Source, Destination>(); } My problem has been solved. Look at this example: I ran into this as well in AutoMapper 11. public class SetSomeAction : IMappingAction<SomeModel, AutoMapper can map to destination constructors based on source members: public class Source { public int Value { get ; set ; } } public class SourceDto { public SourceDto ( int value ) { _value = value ; } private int _value ; public int Value { get { return _value ; } } } var configuration = new MapperConfiguration ( cfg => cfg . I want to register all the Mappings in my Business Layer to Data Layer, and Data Layer to Business Layer classes just as my Business Layer assembly loads. e IEmployeeType. Improve this question. You don't need to map each item in a loop. AutoMapper is the convention-based object to object mapper. An example scenario would be creating a Data Transfer Objects(DTOs) from a Data Model (Entity). Follow edited Aug 28, 2020 at 11:07. Profile. Edit for clarification: I am not looking for a link to the documentation, which I have read, or an explanation of the basic syntax. Commented Jan 16, 2024 at 15:51. I have some Automapper profiles, and I create two different mapper instances at runtime according to the situations. Something like this var config = Profiles permit the programmer to organize maps into classes, enhancing code readability and maintainability. AutoMapperMappingException: 'Missing type map configuration or unsupported mapping. AutoMapper. Here’s a step-by-step guide on how to configure dependency injection and C# – Unit testing a AutoMapper Profile mappings. ConvertUsing<Core. This answer is what I was looking for, thank you! – E4est. B. However if you have AutoMapper. Map<Domain. I have two classes and map one to other with Automapper. Different people prefer different place to place mapping profile classes. Profile classes defined in a different assembly, or spread across multiple assemblies, you can use the RegisterProfiles() overloads that take Assembly arguments. Id, opts => I am using autofac as IOC and Automapper to map my model and entities. AutoMapper is an object-to-object mapping library that helps transform one object type into another. AutoMapper provides configuration testing in the form of the AssertConfigurationIsValid method. When invoking Map, you can configure the conversion context with your custom parameter(s) using the second callback argument. 0. Currently I am using a static class to do this task for me: public static class AutoMapperBootstrapper { public static void InitMappings() { Mapper. AutoMapper 9 generic extension static class. The AutoMapper is also injected into the service as IMapper and contains all mapping profiles of the application. If you'd rather avoid reflection, then you can get at least some of the information from the profiles directly by casting them to IProfileConfiguration. The root cause of your issue is the incorrect usage of the AddAutoMapper extension method. Because of this, based on the AutoMapper Using Profiles in Automapper to map the same types with different logic with DI support for CustomValue Resolvers. Automapper Profile. On WebAPI assembly I registered automapper profiles automatically with this line: services. In ConfigureServices(): // Adds AutoMapper to DI configuration and automagically scans the // current assembly for any classes that inherit Profile // and registers their configuration in AutoMapper services. Usually you put all your creates in bootstrapper or startup function. The answer below for 5. Starting with version 13. You can warp your mapping configurations in the form of grouped (in separated Profiles) then register all of theme by Mapper. adding profiles to automapper after initialisation. 1. Member The way I've handled this in some ASP. I also don't know why you would want to map a productview to a store. NET Core, Cloud Computing, Microservices, Design Patterns and still learning One of the inspirations behind AutoMapper was to eliminate not just the custom mapping code, but eliminate the need for manual testing. Net Core Dependency Injection. So where your default map would be. C into ABC. Profile class, there are a couple issues here: The cfg. Once you have your types you can create a map for the two types using a MapperConfiguration and CreateMap. AfterMap<AfterMapAction>(); } 一、ABP的Profile有什么用？Profile用来编写AutoMapper的映射规则，在Profile类构造方法中编写的规则最后会配置到AutoMapper中，实现实体到DTO的自动映射。二、代码浅析 1. 1 and AutoMapper. So having a single profile in the start up file of the MVC and/or API project could work, but would involve some duplication. It helps eliminate repetitive and error-prone code when copying data from one object to another. For small projects with only one assembly, this is all you need. You’ll need to move all your Add the main AutoMapper Package to your solution via NuGet. Net project. My personal opinion I always create a project called AutoMapperMapping for placing all automapper related stuffs and refer the solution dll in the places which I need them. This is a good example of why automapper doesn't map How can i unit test a profile that uses AfterMap with IMappingAction that has an injected service. Also, regarding the first way you try to register your profiles in the Autofac container: How can I add AutoMapper Profiles to my mapper config using a for loop? 1 Manipulate the mapping expression of the profile of Automapper at runtime. The automapper configuration currently happens in a static class ASP. Below example “SourceMappingProfile” is a profile class with constructor injection of service instance type i. It's mainly useful for mapping complex objects, such as Data Transfer AutoMapper is a popular open-source library in C# that simplifies mapping data between different classes or objects. Below is how you can unit test the AutoMapper profiles, you will need to make sure you Profile for AutoMapper that creates maps based on contracts. 1; It seems my profiles are not being loaded, every time I call the mapper. –. Kenci You can absolutely do exactly what you want using a custom ITypeConverter<TSource, TDestination> implementation. Type converters are globally scoped, so that any time you map from type Foo to type Bar in any mapping, the type converter will be used. What Be sure to remove all such code before release. AddAutoMapper(); You can’t inject dependencies into Profile classes, but you can do it in IMappingAction implementations. CreateMapper(); This way, we need to specify the source and the destination type as type params to the Asp. Steps include installation, service registration, model creation, mapping between domain and view models, reverse mapping, and handling complex object mapping. Is there a reason you want to mock it in your tests? (You can always configure AutoMapper differently for test use, but that's not the same thing as Mocking it). cs public MappingProfile() { CreateMap<string, string>() . EF6: Extension Methods for EF6. Net Core and AutoMapper. You can’t inject dependencies into Profile classes, but you can do it in IMappingAction implementations. You can warp your mapping configurations in the form of grouped (in separated Profiles) AutoMapper uses a convention-based matching algorithm to match up source to destination values. This method scans assemblies for profiles (and other AutoMapper components) and registers an IMapper component in the DI container using the configuration found. Map<>() has no parameters for additional options or objects, unlike the normal AutoMapper. If you need to call an async method to get some additional data, you have a See this SO Question about mapping from the view model back to the domain. Profile I'll show a simplified example of my issue: public class FlavorProfile : Profile { public FlavorProfile() { CreateMap<FlavorEntity, FlavorDto>(); } } Now I want to map a class using a particular function: How to inject a service in AutoMapper Profile class? 0 Telling injected automapper to use specific mapping profile in map function. 0 and above and if you are using Profile to create mapper: public class OrderMapper : Profile { public OrderMapper() { CreateMap<Order, OrderDto Value Converters . Initialize(a => a. Inside one of the mapping profiles, for a member that exists only in the destination object, I need to set the value according to a value from the settings file (the appsettings. 1 source). Value transformers apply an additional transformation to a single type. 0. If you are following three layer architecture then you can place I'm using Automapper with dependency injection, so I've some mappers using AutoMapper.
