服务端代码：

using System;using System.Collections.Generic;using System.Text;using System.Net;using System.Net.Sockets;using System.IO;using System.Threading;namespace SocketServer{    class Server    {        //创建监听对象        private static TcpListener tcpServer = null;        public Server()        {            //获取本机ip地址            IPAddress iPAddress = IPAddress.Any;            //指定在哪个端口上监听            tcpServer = new TcpListener(iPAddress, 999);            //999是端口号，可以随便改 0-1024，主要不要和什么80,8080之类的常用端口号相冲突哦。              //开始监听            tcpServer.Start();            Console.WriteLine("监听已启动......");            //把收发放到后台线程运行            Thread t1 = new Thread(ExceMethod);            t1.IsBackground = true;            t1.Start();        }        private static void ExceMethod()        {            byte[] msg = Encoding.UTF8.GetBytes("服务端发出的数据");            while (true)            {                //接收数据的缓存                byte[] bytes = new byte[256];                //接收监听到的客户端                TcpClient client = tcpServer.AcceptTcpClient();                while (true)                {                    try                    {                        //把客户端的发送的数据存到缓冲区                         int i = client.Client.Receive(bytes);                        Console.WriteLine(DateTime.Now.ToString("G") + "接受:" + Encoding.UTF8.GetString(bytes));                        Console.WriteLine("\n");                        //发送数据给客户端                        client.Client.Send(msg);                    }                    catch                    {                        break;                    }                }                client.Close();                Thread.Sleep(1000);//10000单位是毫秒，系统在运行过程中，稍微有点停顿，个人感觉会更好一点。              }        }    }}

客户端代码：

using System;using System.Text;using System.Collections;using System.ComponentModel;using System.Net;using System.Net.Sockets;using System.IO;using System.Threading;using System.Collections.Generic;using System.Runtime.InteropServices;namespace SocketClient{    class Client    {        //创建客户端        private static TcpClient client = new TcpClient();        public Client()        {            //和服务器连接            client.Connect("127.0.0.1", 999);            Console.WriteLine("连接成功......");            //在线程收发数据            Thread t1 = new Thread(ExceMethod);            t1.IsBackground = true;            t1.Start();        }        private static void ExceMethod()        {            while (true)            {                byte[] data = Encoding.UTF8.GetBytes("客户端发出的数据");                //接收连接服务器的socket对象                Socket socket = client.Client;                //给服务器发送数据                socket.Send(data, data.Length, SocketFlags.None);                Console.WriteLine("发送成功:" + Encoding.UTF8.GetString(data));                  //接收服务器发送的数据                socket.Receive(data, SocketFlags.None);                Console.WriteLine("接受数据:" + Encoding.UTF8.GetString(data));                Thread.Sleep(1000);            }        }    }}
