使用与父类型相同的类型参数解析Unity中的开放泛型类型

Question

我有一个抽象的泛型类LogWriter<T>。我有一个名为MultiClientLogWriter<T>的实现，它包含多个LogWriter<T>实例并写入所有实例。我想让一个MutliClientLogWriter包含几个不同类型的编写器默认。我有这个代码，但它不起作用，因为（当然）你无法解析开放的泛型类型：

unityContainer.RegisterType(typeof (LogWriter<>), typeof (TraceLogWriter<>), "trace", new PerRequestLifetimeManager(),
  new InjectionConstructor(Severity.Debug));

unityContainer.RegisterType(typeof (LogWriter<>), typeof (LogSinkWriter<>), "sink",
  new PerRequestLifetimeManager(), new InjectionConstructor(Severity.Debug, logSink));

unityContainer.RegisterType(typeof (LogWriter<>), typeof (MultiClientLogWriter<>),
   new PerRequestLifetimeManager(),
   new InjectionConstructor(unityContainer.Resolve(typeof (LogWriter<>), "sink"),
   unityContainer.Resolve(typeof (LogWriter<>), "trace")));

但是，我希望这个链接下去（也就是说，如果请求MultiClientLogWriter<Controller>我想要一个LogSinkWriter<Controller>等等），所以你认为会有一些方法实现这一目标。
