How Do I...Compile a Client Against an Interface?

This example illustrates how to build a client that does not reference a server object at compile time. The following code example demonstrates the client code.

		
using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;

namespace Microsoft.Samples.Remoting.RemotingSamples {
  public class Client {
    public static int Main(string [] args) {
      TcpChannel chan = new TcpChannel();
      ChannelServices.RegisterChannel(chan);
      IHello obj = (IHello)Activator.GetObject(typeof(RemotingSamples.IHello), "tcp://localhost:8085/SayHello");
      if (obj == null) System.Console.WriteLine("Could not locate server");
      else Console.WriteLine(obj.HelloMethod("Caveman"));
      return 0;
    }
  }
}

The client calls GetObject on an endpoint without knowing what the exact object type is. All it knows is that the object implements IHello.
