C# TCP实现多个客户端与服务端 数据 传输

C# TCP实现多个客户端与服务端 数据 传输

实现一个客户端和一个服务端通信
可以同时收发多条信息
使用C#语言，通过socket进行通信，基于TCP协议
服务端代码：

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Threading.Tasks;
 6 using System.Net;
 7 using System.Net.Sockets;
 8 using System.Threading;

10 namespace testServer
11 {
12     class Program

14         static void Main(string[] args)
15         {
16             Socket server = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);//创建服务端
17             EndPoint point = new IPEndPoint(IPAddress.Prase("127.0.0.1"), 8888);
18             server.Bind(point);//绑定端口号和IP
19             server.Listen(10);//开启监听
20             Console.WriteLine("服务器开启。。。。");
21             Socket client = server.Accept();//保存连接进来的客户端
22             client.Send(Encoding.UTF8.GetBytes("你已经进入服务"));//给客户端发送消息，提示客户端连接成功
23 
24 
25             Thread t1 = new Thread(reciveMsg);
26             t1.Start(client);//开启线程接收消息
27 
28             Thread t2 = new Thread(sendMsg);
29             t2.Start(client);//开启线程发送消息
30 
31         }
32 
33         static void reciveMsg(object obj)
34         {
35             Socket client = obj as Socket;
36             while (true)
37             {
38                 byte[] buffer = new byte[1024];
39                 try
40                 {
41                     int length = client.Receive(buffer);
42                     string res = Encoding.UTF8.GetString(buffer, 0, length);
43                     Console.WriteLine("接收到的消息：" + res);
44                 }
45                 catch (Exception e)
46                 {
47                     IPEndPoint point = client.RemoteEndPoint as IPEndPoint;
48                     Console.WriteLine(point.ToString()+"断开连接。。。");
49                     break;
50                 }
51 
52             }
53 
54         }
55 
56         static void sendMsg(object obj)
57         {
58             Socket client = obj as Socket;
59             while (true)
60             {
61                 string s = Console.ReadLine();
62                 client.Send(Encoding.UTF8.GetBytes(s));
63             }
64         }
