本文以实例详述了C#实现Socket通信的解决方法，具体实现步骤如下：
1、首先打开VS新建两个控制台应用程序：
ConsoleApplication_socketServer和ConsoleApplication_socketClient。
2、在ConsoleApplication_socketClient中输入以下代码：
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Net; using System.Net.Sockets; namespace ConsoleApplication_socketClient { class Program { static Socket clientSocket; static void Main(string[] args) { //将网络端点表示为IP地址和端口 用于socket侦听时绑定 IPEndPoint ipep = new IPEndPoint(IPAddress.Parse("*.*.*.*"), 3001); //填写自己电脑的IP或者其他电脑的IP，如果是其他电脑IP的话需将ConsoleApplication_socketServer工程放在对应的电脑上。 clientSocket = new Socket(ipep.AddressFamily,SocketType.Stream,ProtocolType.Tcp); //将Socket连接到服务器 try { clientSocket.Connect(ipep); String outBufferStr; Byte[] outBuffer = new Byte[1024]; Byte[] inBuffer = new Byte[1024]; while (true) { //发送消息 outBufferStr = Console.ReadLine(); outBuffer = Encoding.ASCII.GetBytes(outBufferStr); clientSocket.Send(outBuffer, outBuffer.Length, SocketFlags.None); //接收服务器端信息 clientSocket.Receive(inBuffer, 1024, SocketFlags.None);//如果接收的消息为空 阻塞 当前循环 Console.WriteLine("服务器说："); Console.WriteLine(Encoding.ASCII.GetString(inBuffer)); } } catch { Console.WriteLine("服务未开启！"); Console.ReadLine(); } } } }
3、在ConsoleApplication_socketServer中输入以下代码：
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using System.Net; using System.Net.Sockets; using System.Threading; namespace ConsoleApplication_socketServer { class Program { static Socket serverSocket; static Socket clientSocket; static Thread thread; static void Main(string[] args) { IPEndPoint ipep = new IPEndPoint(IPAddress.Any, 3001); serverSocket = new Socket(ipep.AddressFamily, SocketType.Stream, ProtocolType.Tcp); serverSocket.Bind(ipep); serverSocket.Listen(10); while (true) { clientSocket = serverSocket.Accept(); thread = new Thread(new ThreadStart(doWork)); thread.Start(); } } private static void doWork() { Socket s = clientSocket;//客户端信息 IPEndPoint ipEndPoint = (IPEndPoint)s.RemoteEndPoint; String address = ipEndPoint.Address.ToString(); String port = ipEndPoint.Port.ToString(); Console.WriteLine(address + ":" + port + " 连接过来了"); Byte[] inBuffer = new Byte[1024]; Byte[] outBuffer = new Byte[1024]; String inBufferStr; String outBufferStr; try { while (true) { s.Receive(inBuffer, 1024, SocketFlags.None);//如果接收的消息为空 阻塞 当前循环 inBufferStr = Encoding.ASCII.GetString(inBuffer); Console.WriteLine(address + ":" + port + "说:"); Console.WriteLine(inBufferStr); outBufferStr = Console.ReadLine(); outBuffer = Encoding.ASCII.GetBytes(outBufferStr); s.Send(outBuffer, outBuffer.Length, SocketFlags.None); } } catch { Console.WriteLine("客户端已关闭！"); } } } }
4、先运行ConsoleApplication_socketServer，后运行ConsoleApplication_socketClient就可以通信了。
本例给出了基本的实现代码，读者可以根据自身的需求进一步完成个性化功能。
