1，远程对象，必须继承MarshalByRefObject类

using System;
using System.Collections.Generic;
using System.Text;namespace RemotingSamples
{
    //远程对象类型
    public class HelloServer : MarshalByRefObject
    {
        public HelloServer()
        {
            Console.WriteLine("HelloServer activated");
        }public String HelloMethod(String name)
        {
            Console.WriteLine("Server Hello.HelloMethod : {0}", name);
            return "Hi there " + name;
        }
    }
}

2，服务器端

using System;//命名空间导入
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Remoting.Channels.Http;namespace RemotingSamples 
{//服务器类
    public class Server
    {
        public static int Main(string [] args) 
        {
            //tcp通道
            TcpChannel chan1 = new TcpChannel(8085);//http通道
            HttpChannel chan2 = new HttpChannel(8086);//注册通道
            ChannelServices.RegisterChannel(chan1);
            ChannelServices.RegisterChannel(chan2);//服务器端激活
            RemotingConfiguration.RegisterWellKnownServiceType
               (typeof(HelloServer),           //远程对象类型
                "SayHello",                     //url
                WellKnownObjectMode.Singleton   //唯一实例
                );
            System.Console.WriteLine("Press Enter key to exit");
            System.Console.ReadLine();
            return 0;
        }

    }
}

3，客户端方法

using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Remoting.Channels.Http;
using System.IO;namespace RemotingSamples 
{
    public class Client
    {
        public static void Main(string[] args)
        {
           
            //使用TCP通道得到远程对象
            TcpChannel chan1 = new TcpChannel();
            ChannelServices.RegisterChannel(chan1);
           
            HelloServer obj1 = (HelloServer)Activator.GetObject(
                typeof(RemotingSamples.HelloServer),
                "tcp://localhost:8085/SayHello");
           
            if (obj1 == null)
            {
                System.Console.WriteLine(
                    "Could not locate TCP server");
            }//使用HTTP通道得到远程对象
            HttpChannel chan2 = new HttpChannel();
            ChannelServices.RegisterChannel(chan2);
            HelloServer obj2 = (HelloServer)Activator.GetObject(
                typeof(RemotingSamples.HelloServer),
                "http://localhost:8086/SayHello");
            if (obj2 == null)
            {
                System.Console.WriteLine(
                    "Could not locate HTTP server");
            }//调用远程方法
            Console.WriteLine(
                "Client1 TCP HelloMethod {0}",
                obj1.HelloMethod("Caveman1"));
            Console.WriteLine(
                "Client2 HTTP HelloMethod {0}",
                obj2.HelloMethod("Caveman2"));
            Console.ReadLine();
        }
    }
}
