在。net 6中，你需要在Program.cs文件中添加以下内容:

builder.Services.AddAutoMapper(AppDomain.CurrentDomain.GetAssemblies());

添加到Arve Systad提到的测试中。如果你像我一样，想要维护utz解决方案中提供的继承结构，你可以像这样设置MapperConfiguration:

var mappingProfile = new MappingProfile();
var config = new MapperConfiguration(cfg =>
{
    cfg.AddProfile(mappingProfile);
});
var mapper = new Mapper(config);

我在NUnit中做过这个。

在最新版本的asp.net core中，你应该使用以下初始化:

services.AddAutoMapper(typeof(YourMappingProfileClass));

我想明白了!细节如下:

Add the main AutoMapper Package to your solution via NuGet. Add the AutoMapper Dependency Injection Package to your solution via NuGet. Create a new class for a mapping profile. (I made a class in the main solution directory called MappingProfile.cs and add the following code.) I'll use a User and UserDto object as an example. public class MappingProfile : Profile { public MappingProfile() { // Add as many of these lines as you need to map your objects CreateMap<User, UserDto>(); CreateMap<UserDto, User>(); } } Then add the AutoMapperConfiguration in the Startup.cs as shown below: public void ConfigureServices(IServiceCollection services) { // .... Ignore code before this // Auto Mapper Configurations var mapperConfig = new MapperConfiguration(mc => { mc.AddProfile(new MappingProfile()); }); IMapper mapper = mapperConfig.CreateMapper(); services.AddSingleton(mapper); services.AddMvc(); } To invoke the mapped object in code, do something like the following: public class UserController : Controller { // Create a field to store the mapper object private readonly IMapper _mapper; // Assign the object in the constructor for dependency injection public UserController(IMapper mapper) { _mapper = mapper; } public async Task<IActionResult> Edit(string id) { // Instantiate source object // (Get it from the database or whatever your code calls for) var user = await _context.Users .SingleOrDefaultAsync(u => u.Id == id); // Instantiate the mapped data transfer object // using the mapper you stored in the private field. // The type of the source object is the first type argument // and the type of the destination is the second. // Pass the source object you just instantiated above // as the argument to the _mapper.Map<>() method. var model = _mapper.Map<UserDto>(user); // .... Do whatever you want after that! } }

在。net 6中，你需要在Program.cs文件中添加以下内容:

builder.Services.AddAutoMapper(AppDomain.CurrentDomain.GetAssemblies());

Asp。Net Core 2.2与AutoMapper.Extensions.Microsoft.DependencyInjection。

public class MappingProfile : Profile
{
  public MappingProfile()
  {
      CreateMap<Domain, DomainDto>();
  }
}

在Startup.cs

services.AddAutoMapper(typeof(List.Handler));
