我想到了！详细信息如下：

1. 通过NuGet将主要的AutoMapper软件包添加到您的解决方案中。

2. 通过NuGet将AutoMapper依赖项注入程序包添加到您的解决方案中。

3. 为映射配置文件创建一个新类。（我在主解决方案目录中创建了一个名为的类，MappingProfile.cs并添加了以下代码。）我将使用Userand UserDto对象作为示例。

   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>();
   }
   

   }

4. 然后在Startup.cs如下所示添加AutoMapperConfiguration ：

   public void ConfigureServices(IServiceCollection services) {
   // .... Ignore code before this
   

   // Auto Mapper Configurations
   var mappingConfig = new MapperConfiguration(mc =>
   {
   mc.AddProfile(new MappingProfile());
   });

   IMapper mapper = mappingConfig.CreateMapper();
   services.AddSingleton(mapper);
   
   services.AddMvc();
   

   }

5. 要在代码中调用映射的对象，请执行以下操作：

   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!
   }
   

   }

我希望这可以帮助某人从ASP.NET Core重新开始！我欢迎任何反馈或批评，因为我还是.NET世界的新手！
