1、服务端

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Remoting.Channels.Http;
using GeneralService;

namespace RemotingServer
{
    public class Server
    {
        public static int Main(string[] args)
        {
            //TCP协议传输消息的信道实现
            TcpChannel chan1 = new TcpChannel(8085);
            //为远程调用实现使用HTTP协议传输消息的客户端通道
            HttpChannel chan2 = new HttpChannel(8086);
            //提供帮助进行远程处理信道注册、解析和URL发现的静态方法。无法继承此类
            ChannelServices.RegisterChannel(chan1, false);
            ChannelServices.RegisterChannel(chan2,false);
            //提供多种配置远程结构的静态方法
            RemotingConfiguration.RegisterWellKnownServiceType
                (
               typeof(HelloServer),
                "SayHello",
                WellKnownObjectMode.Singleton
                );

System.Console.WriteLine("Press Enter key to exit");
            System.Console.ReadLine();
            return 0;
        }
    }
}

2、服务类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace GeneralService
{
    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;
        }
    }

}

3、客户端

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Remoting.Channels.Http;
using GeneralService;

namespace RemotingClient
{
    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,false);
            //Activator包含特定的方法，用以在本地或从远程创建对象类型、或获取对现有远程对象的引用。无法继承此类
            HelloServer obj1 = (HelloServer)Activator.GetObject(
                typeof(GeneralService.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,false);
            HelloServer obj2 = (HelloServer)Activator.GetObject(
                typeof(GeneralService.HelloServer),
                "http://localhost:8086/SayHello");
            if (obj2 == null)
            {
                System.Console.WriteLine(
                    "Could not locate HTTP server");
            }

Console.WriteLine(
                "Client1 TCP HelloMethod {0}",
                obj1.HelloMethod("Caveman1"));
            Console.WriteLine(
                "Client2 HTTP HelloMethod {0}",
                obj2.HelloMethod("Caveman2"));
            Console.ReadLine();
        }
    }
}
