代码是抄来了，找不到出处了，经测试代码简洁可用

服务端代码：

using System;using System.Text;using System.Net.Sockets;using System.Net;using System.Threading;namespace SocketServer{    internal class Program    {        private static readonly byte[] Result = new byte[1024];        private const int MyProt = 8885; //端口         private static Socket _serverSocket;        private static void Main()        {            //服务器IP地址            var ip = IPAddress.Parse("127.0.0.1");            _serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);            _serverSocket.Bind(new IPEndPoint(ip, MyProt));  //绑定IP地址：端口            _serverSocket.Listen(10);    //设定最多10个排队连接请求            Console.WriteLine("启动监听{0}成功", _serverSocket.LocalEndPoint);            //通过Clientsoket发送数据            var myThread = new Thread(ListenClientConnect);            myThread.Start();            Console.ReadLine();        }        /// <summary>        /// 监听客户端连接        /// </summary>        private static void ListenClientConnect()        {            while (true)            {                var clientSocket = _serverSocket.Accept();                clientSocket.Send(Encoding.ASCII.GetBytes("Server Say Hello"));                var receiveThread = new Thread(ReceiveMessage);                receiveThread.Start(clientSocket);            }        }        /// <summary>        /// 接收消息        /// </summary>        /// <param name="clientSocket"></param>        private static void ReceiveMessage(object clientSocket)        {            var myClientSocket = (Socket)clientSocket;            while (true)            {                try                {                    //通过clientSocket接收数据                    var receiveNumber = myClientSocket.Receive(Result);                    Console.WriteLine("接收客户端{0}消息{1}", myClientSocket.RemoteEndPoint, Encoding.ASCII.GetString(Result, 0, receiveNumber));                }                catch(Exception ex)                {                    Console.WriteLine(ex.Message);                    myClientSocket.Shutdown(SocketShutdown.Both);                    myClientSocket.Close();                    break;                }            }        }    }}

客户端代码：

using System;using System.Text;using System.Net;using System.Net.Sockets;using System.Threading;namespace SocketClient{    class Program    {        private static readonly byte[] Result = new byte[1024];        private static void Main()        {            //设定服务器IP地址            var ip = IPAddress.Parse("127.0.0.1");            var clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);            try            {                clientSocket.Connect(new IPEndPoint(ip, 8885)); //配置服务器IP与端口                Console.WriteLine("连接服务器成功");            }            catch            {                Console.WriteLine("连接服务器失败，请按回车键退出！");                return;            }            //通过clientSocket接收数据            var receiveLength = clientSocket.Receive(Result);            Console.WriteLine("接收服务器消息：{0}",Encoding.ASCII.GetString(Result,0,receiveLength));            //通过 clientSocket 发送数据            for (int i = 0; i < 10; i++)            {                try                {                    Thread.Sleep(1000);    //等待1秒钟                    var sendMessage = "client send Message Help " + DateTime.Now;                    clientSocket.Send(Encoding.ASCII.GetBytes(sendMessage));                    Console.WriteLine("向服务器发送消息：{0}" + sendMessage);                }                catch                {                    clientSocket.Shutdown(SocketShutdown.Both);                    clientSocket.Close();                    break;                }            }            Console.WriteLine("发送完毕，按回车键退出");            Console.ReadLine();        }    }}
