此为控制台程序，服务器启动侦听，客户端进行连接，并向服务器发送字符串，服务器将其转化为大写并发挥客户机（在同一台主机上运行）。服务器端using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Net;using System.Net.Sockets;namespace SynTCPServer class Program static void Main(string args) Socket Listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); /IPAddress myip = Dns.GetHostAddresses(Dns.GetHostName()1; /String str = Dns.GetHostName(); /Console.WriteLine(str); /Console.WriteLine(myip); /foreach (IPAddress ip in myip) / / Console.WriteLine(ip); /Console.Read(); IPEndPoint iep = new IPEndPoint(IPAddress.Parse() , 5555); Listener.Bind(iep); Listener.Listen(10); Console.WriteLine(等待连接); Socket socket = Listener.Accept(); Console.WriteLine(连接成功，等待接受数据); Byte buffer = new byte128; int count = socket.Receive(buffer, 0, buffer.Length, SocketFlags.None); Console.WriteLine(成功接受数据); String strRcv = Encoding.ASCII.GetString(buffer, 0, count); string strsnt = strRcv.ToUpper(); buffer = Encoding.ASCII.GetBytes(strsnt); count = socket.Send(buffer, 0, buffer.Length, SocketFlags.None); Console.WriteLine(发送数据); socket.Shutdown(SocketShutdown.Both); socket.Close(); Listener.Close(); Console.Read(); 客户端using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Net;using System.Net.Sockets;namespace SynTcpclient class Program static void Main(string args) Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); IPEndPoint RmtEP = new IPEndPoint(IPAddress.Parse(), 5555); socket.Connect(RmtEP); Console.WriteLine(); String StrInput = Console.ReadLine(); Byte data = Encoding.ASCII.GetBytes(StrInput); socket.Send(data, 0, data.Length, SocketFlags.None); Int32 count=socket.Receive(data,0,data.Length,SocketFlags.None); String strRcv = Encoding.ASCII.GetString(data, 0, count);
