Csharp 使用带有参数和曲面的注入失败(&Q；)

我正在try 注册我创建的一些端点，然而，Autofac抛出了一个异常，说我还没有注册我的BControl类.这是我的注册码:

    builder.RegisterType<GControlEndpoint>().As<IBusConsumer>().SingleInstance();
    builder.RegisterType<BControlEndpoint>().As<IBusConsumer>().SingleInstance();

    builder.RegisterType<BSControlEndpoint>().As<IBusConsumer>().SingleInstance()
      .WithParameter((pi, c) => pi.Name == "bControlEndpoint",
        (pi, c) => c.Resolve<BControlEndpoint>())
      .WithParameter((pi, c) => pi.Name == "gControlEndpoint",
        (pi, c) => c.Resolve<GControlEndpoint>());

我的BSControlEndpoint代码如下:

  private BControlEndpoint bControlEndpoint;
  private GControlEndpoint gControlEndpoint;

  public BSControlEndpoint(
    BControlEndpoint bControlEndpoint,
    GControlEndpoint gControlEndpoint)
  {
    this.bControlEndpoint = bControlEndpoint;
    this.gControlEndpoint = gControlEndpoint;
  }

任何帮助都将不胜感激.

Autofac错误为:

Autofac.Core.Registration.ComponentNotRegisteredException: The requested service 'Sa.BControlEndpoint' has not been registered. To avoid this exception, either register a component to provide the service, check for service registration using IsRegistered(), or use the ResolveOptional() method to resolve an optional dependency.个
