ASP.NET MVC Core DI注入服务列表

Question

如何获得这样的新DI支持注入？

  public class Thing{

    public Thing(IList<IService> someServices) {

       ...
    }
  }

  public class ServiceA : IService { }
  public class ServiceB : IService { }
  public class ServiceB : IService { }

  public class Startup {
    ...

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddTransient<IService, ServiceA>()
                .AddTransient<IService, ServiceB>()
                .AddTransient<IService, ServiceC>();
    }
  }

Answer 1

从ASP.NET Core 2.0开始,如果您注入依赖项IEnumerable<IService>而不是注入依赖项IList<IService>,则可以放弃注册列表本身,只留下单独的服务注册.

Answer 2

懂了（简体）

.AddTransient(p => p.GetServices<IService>())

但是您必须完全符合ctor的期望

.AddTransient<IList<IService>>(p => p.GetServices<IService>().ToList())
