服务器端：

14         static Socket clientSocket; 
15         static Thread thread; 
16         static void Main(string[] args) 
17         { 
18             //将网络端点表示为IP地址和端口 用于socket侦听时绑定 
19             IPEndPoint ipep = new IPEndPoint(IPAddress.Any,3001); 
20             //使用指定的地址族、套接字类型和协议初始化 Socket 类的新实例。 
21             serverSocket = new Socket(ipep.AddressFamily, SocketType.Stream, ProtocolType.Tcp); 
22             //将所创建的Socket与IPEndPoint绑定 
23             serverSocket.Bind(ipep); 
24             //设置套接字为收听模式 定队列中最多可容纳的等待接受的传入连接数为10 
25             serverSocket.Listen(10); 
26             //在Socket上接收接入的连接 
27             while (true) { 
28                 //serverSocket.Accept()接收客户端Socket的连接请求 当程序运行到serverSocket.Accept()时会等待直到有客户端Socket发起连接请求时 获取客户端Socket 
29                 clientSocket = serverSocket.Accept(); 
30                  
31                 thread = new Thread(new ThreadStart(TestServer.doWork)); 
32                 thread.Start();

34             } 
35         }

37             Socket s = clientSocket; 
38  
39             //客户端信息 
40             IPEndPoint ipEndPoint = (IPEndPoint)s.RemoteEndPoint; 
41             String address = ipEndPoint.Address.ToString(); 
42             String port = ipEndPoint.Port.ToString(); 
43             Console.WriteLine(address+":"+port+" 连接过来了"); 
44  
45             Byte[] inBuffer = new Byte[1024]; 
46             Byte[] outBuffer = new Byte[1024]; 
47             String inBufferStr; 
48             String outBufferStr; 
49             while (true) 
50             { 
51                 s.Receive(inBuffer, 1024, SocketFlags.None);//如果接收的消息为空 阻塞 当前循环 
52  
53                 inBufferStr = Encoding.ASCII.GetString(inBuffer); 
54  
55                 Console.WriteLine(address + ":" + port + "说:"); 
56                 Console.WriteLine(inBufferStr); 
57  
58                 outBufferStr = "Welcome To  Server"; 
59  
60                 outBuffer = Encoding.ASCII.GetBytes(outBufferStr); 
61                 s.Send(outBuffer, outBuffer.Length, SocketFlags.None); 
62             } 
63         } 
64          
65     } 
66 }

14         { 
15             //将网络端点表示为IP地址和端口 用于socket侦听时绑定 
16             IPEndPoint ipep = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 3001); 
17  
18             clientSocket = new Socket(ipep.AddressFamily,SocketType.Stream,ProtocolType.Tcp); 
19  
20             //将Socket连接到服务器 
21             clientSocket.Connect(ipep); 
22  
23             String outBufferStr; 
24             Byte[] outBuffer = new Byte[1024]; 
25             Byte[] inBuffer = new Byte[1024]; 
26             while (true) 
27             { 
28                 //发送消息 
29                 outBufferStr = Console.ReadLine(); 
30  
31                 outBuffer = Encoding.ASCII.GetBytes(outBufferStr); 
32                 clientSocket.Send(outBuffer, outBuffer.Length, SocketFlags.None); 
33  
34                 Console.WriteLine("服务器响应："); 
35                 //接收服务器端信息 
36                 clientSocket.Receive(inBuffer, 1024, SocketFlags.None); 
37                 Console.WriteLine(Encoding.ASCII.GetString(inBuffer)); 
38             } 
39         } 
40     } 
41 }

以上的代码很简单，但可以实现服务器端和客户端的通信，但是代码中存在隐患，因为只是入门级别的，所以作者没有考虑到那么多。
