Setup Automapper in ASP.NET Core

標籤：action   extension   map   style   span   package   ret   color   修改   

1、添加Nuget Package

Install-Package AutoMapper.Extensions.Microsoft.DependencyInjection

2、修改Startup.cs

public void ConfigureServices(IServiceCollection services){    services.AddMvc();    services.AddAutoMapper();}

3、從Profile派生一個自訂的映射配置類

public class MappingProfile : Profile{    public MappingProfile()    {        CreateMap<User, UserDTO>();    }}

4、在代碼中調用映射對象

public class HomeController : Controller{    private readonly IMapper _mapper;    public HomeController(IMapper mapper)    {        _mapper = mapper;    }    public IActionResult Index()    {        var user = new User        {            Id = 1,            Name = "bidianqing"        };        var userDTO = _mapper.Map<User, UserDTO>(user);        return View();    }}
