(2)最简单的Remoting程序

(1) 编写3步走
(类库)对象General
(控制台应用程序)服务器端Server:添加对象的dll引用
(控制台应用程序)客户端Client:添加对象的dll引用

(2) 对象
using System;
using System.Collections.Generic;
using System.Text;
namespace RemotingExample
{
    public class Hello : MarshalByRefObject
    {
        public Hello()
        {
            Console.WriteLine("Hello对象被建立");
        }

        public string SayHello(string strClientName)
        {
            return " Hello ! " + strClientName;
        }
    }
}

(3) 服务期端代码
using System;
using System.Collections.Generic;
using System.Text;
//添加的using
using RemotingExample;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
//添加System.Runtime.Remoting引用才能添加以下2个using
using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Remoting.Channels.Http;

namespace RemotingExample
{
    public class Server
    {
        public static int Main(string[] args)
        {
            TcpChannel myTcpChannel = new TcpChannel(8085);//申请tcp通道
            HttpChannel myHttpChannel = new HttpChannel(8086);//申请http通道
            ChannelServices.RegisterChannel(myTcpChannel, false);//注册tcp通道
            ChannelServices.RegisterChannel(myHttpChannel, false);//注册http通道

            RemotingConfiguration.RegisterWellKnownServiceType(
                typeof(Hello),
                "SayHello",
                WellKnownObjectMode.Singleton
                );

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

(4) 客户端代码
using System;
using System.Collections.Generic;
using System.Text;
//添加的using
using RemotingExample;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
//添加System.Runtime.Remoting引用才能添加以下2个using
using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Remoting.Channels.Http;

namespace RemotingExample
{
    class Client
    {
        public static int Main(string[] args)
        {
            //使用TCP通道获得远程对象
            TcpChannel myTcpChannel = new TcpChannel();
            ChannelServices.RegisterChannel(myTcpChannel, false);
            Hello myHelloTCP = (Hello)Activator.GetObject(typeof(Hello), "tcp://localhost:8085/SayHello");
            if (myHelloTCP == null)
            {
                System.Console.WriteLine("Could not locate TCP server");
            }
            //使用HTTP通道获得远程对象
            HttpChannel myHttpChannel = new HttpChannel();
            ChannelServices.RegisterChannel(myHttpChannel, false);
            Hello myHelloHTTP = (Hello)Activator.GetObject(typeof(Hello), "http://localhost:8086/SayHello");
            if (myHelloHTTP == null)
            {
                System.Console.WriteLine("Could not locate TCP server");
            }

            //[TCP]调用远程对象的方法
            System.Console.WriteLine("TCP: " + myHelloTCP.SayHello("miclu"));

            //[HTTP]调用远程对象的方法
            System.Console.WriteLine("HTTP: " + myHelloHTTP.SayHello("miclu"));

            System.Console.ReadLine();
            return 0;
        }
    }
}

这样代码就写死了,下节学习使用Remoting配置文件
