.Net Core + DI：Class 集中接口

Question

我是 .Net Core 和 Microsoft 依赖注入的新手，我想做的是类似于“.ToFactory()”（来自 ninject），我可以创建一个 class 包含我所有的接口服务，避免在我的控制器上使用很多 IMyClassService。在 .Net Framework + Ninject 中，我曾经这样做：

Ninject模块

Bind< IAppServiceFactory >().ToFactory();

IAppServiceFactory class

public interface IAppServiceFactory
{
    IAccessAgreementAppService AccessAgreement { get; }
    IAccessAgreementUserAppService AccessAgreementUser { get; }
    ...

控制器

private readonly IMapper _mapper;
private readonly IAppServiceFactory _appServiceFactory;

public MyController(IMapper mapper,
    IAppServiceFactory appServiceFactory)
{
    _mapper = mapper;
    _appServiceFactory = appServiceFactory;
}

public ActionResult Index()
{
    var all = _appServiceFactory.AccessAgreementUser.GetAll();
}

主要原因是有一个更干净的控制器，而不是

private readonly IAccessAgreementAppService _accessAgreementAppService;
private readonly IAccessAgreementUserAppService _accessAgreementUserAppService;
...
public MyController(IAccessAgreementAppService accessAgreementAppService,
    IAccessAgreementUserAppService accessAgreementUserAppService,
    ...

您可以申请 IServiceProvider 并自行获取服务。

 public MyController(IServiceProvider serviceProvider)
 {
         using (var scope = serviceProvider.CreateScope())
         {
             var service = scope.ServiceProvider.GetRequiredService<IAccessAgreementAppService();
             var all = service.GetAll();    
         }
 }
