c# - 使用反射的 .NET 远程处理

Question

我需要动态加载我在客户端远程处理中使用的接口(interface)程序集。像这样。

static void Main(string[] args)
{
  TcpClientChannel clientChannel = new TcpClientChannel();
  ChannelServices.RegisterChannel(clientChannel, false);

  Assembly interfaceAssembly = Assembly.LoadFile("RemotingInterface.dll");
  Type iTheInterface = 
    interfaceAssembly.GetType("RemotingInterface.ITheService");

  RemotingConfiguration.RegisterWellKnownClientType(iTheInterface,
                                        "tcp://localhost:9090/Remotable.rem");
  object wellKnownObject = Activator.GetObject(iTheInterface, 
                                        "tcp://localhost:9090/Remotable.rem");
}

只是我似乎无法掌握如何调用任何方法，因为我无法转换 Activator.GetObject。如何在编译时不知道接口(interface)的情况下创建 ITheService 的代理？

从MSDN forums得到了答案.

static void Main(string[] args)
{
  TcpClientChannel clientChannel = new TcpClientChannel();
  ChannelServices.RegisterChannel(clientChannel, false);

  Assembly interfaceAssembly = Assembly.LoadFile("RemotingInterface.dll");
  Type iTheInterface = interfaceAssembly.GetType("RemotingInterface.ITheService");

  RemotingConfiguration.RegisterWellKnownClientType(iTheInterface,
                                    "tcp://localhost:9090/Remotable.rem");
  object wellKnownObject = Activator.GetObject(iTheInterface, 
                                    "tcp://localhost:9090/Remotable.rem");

  MethodInfo m = iTheInterface.GetMethod("MethodName");
  m.Invoke(wellKnownObject, new object[] { "Argument"});
}
