C# TCP Server和TCP Client:间多次的数据发送和接收

首先是sever端口

1.  
   using System;
2.  
   using System.Text;
3.  
   using System.Net;
4.  
   using System.Net.Sockets;
5.  
    
6.  
   namespace _301
7.  
   {
8.  
   class Program
9.  
   {
10.  
    private static byte[] result = new Byte[1024];
11.  
    private static int myport = 8012;
12.  
    static Socket serverSocket;
13.  
    static void Main(string[] args)
14.  
    {
15.  
    IPAddress ip = IPAddress.Parse("127.0.0.1");//服务器的IP
16.  
    serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
17.  
    serverSocket.Bind(new IPEndPoint(ip, myport));
18.  
    serverSocket.Listen(10);
19.  
    Console.WriteLine("启动监听{0}", serverSocket.LocalEndPoint.ToString());
20.  
    string sendMessage = "007007";
21.  
    Socket clientsocket = serverSocket.Accept();
22.  
    string s_result = null;
23.  
    while (s_result!="exit")
24.  
    {
25.  
    clientsocket.Send(Encoding.ASCII.GetBytes(sendMessage));
26.  
    Console.WriteLine("向客户端发消息{0}", sendMessage);
27.  
    int receiveNumber = clientsocket.Receive(result);
28.  
    Console.WriteLine("接受客户端{0}消息{1}", clientsocket.RemoteEndPoint.ToString(), Encoding.ASCII.GetString(result, 0, receiveNumber));
29.  
    s_result=Encoding.ASCII.GetString(result,0,receiveNumber);
30.  
    }
31.  
     
32.  
    clientsocket.Shutdown(SocketShutdown.Both);
33.  
    clientsocket.Close();
34.  
    Console.ReadLine();
35.  
     
36.  
     
37.  
     
38.  
     
39.  
    }
40.  
    }
41.  
    }

然后是CLIENT端口

1.  
   using System;
2.  
   using System.Collections.Generic;
3.  
   using System.Linq;
4.  
   using System.Text;
5.  
   using System.Net.Sockets;
6.  
   using System.Net;
7.  
    
8.  
   namespace TCP1
9.  
   {
10.  
    class Program
11.  
    {
12.  
    private static byte[] result = new Byte[1024];
13.  
    static void Main(string[] args)
14.  
    {//创建套接字
15.  
    IPAddress ip = IPAddress.Parse("127.0.0.1");
16.  
    Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
17.  
    //2.连接
18.  
    try
19.  
    {
20.  
    clientSocket.Connect(new IPEndPoint(ip, 8012));
21.  
    Console.WriteLine("连接服务器成功！");
22.  
    }
23.  
    catch
24.  
    {
25.  
    Console.WriteLine("连接服务器失败，请按回车键退出");
26.  
    return;
27.  
    }
28.  
    //3.收发数据
29.  
    string s_result = null;
30.  
    while (s_result != "exit")
31.  
    {
32.  
    int receiveLength = clientSocket.Receive(result);
33.  
    Console.WriteLine("接收服务器消息：{0}", Encoding.ASCII.GetString(result, 0, receiveLength));
34.  
    string sendMessage = "client send Message Hello";
35.  
    clientSocket.Send(Encoding.ASCII.GetBytes(sendMessage));
36.  
    Console.WriteLine("向服务器发送消息:{0}", sendMessage);
37.  
    //4.释放连接
38.  
    }
39.  
    clientSocket.Shutdown(SocketShutdown.Both);
40.  
    //关闭套接字
41.  
    clientSocket.Close();
42.  
    Console.ReadLine();
43.  
    Console.ReadKey();
44.  
     
45.  
    }
46.  
    }
47.  
    }
