C# Socket 通信

本文主要是介绍C# Socket 通信，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

Socket 通信有服务器段和客户端 

.NET 6.0 C# 10.0

服务器端代码如下：

 1 public static void Main(string[] args)
 2     {
 3         Socket serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
 4         IPAddress ipaddress = IPAddress.Parse("127.0.0.1");
 5         IPEndPoint endPoint = new IPEndPoint(ipaddress, 11001);
 6         serverSocket.Bind(endPoint);
 7         serverSocket.Listen(1); //接收客户端的个数
 8         Console.WriteLine($"服务已启动 准备接收数据");
 9         Socket clentSocket = serverSocket.Accept();  //可以接收客户端
10         bool isContinue = true;
11 
12         while (isContinue)
13         {
14             byte[] dataBuffer = new byte[1024];
15             int count = clentSocket.Receive(dataBuffer);
16 
17             string msgReceive = Encoding.UTF8.GetString(dataBuffer, 0, count);
18             if (msgReceive == "stop")
19                 isContinue = false;
20             Console.WriteLine($"接收到的数据 {msgReceive}");
21 
22             string megSend = msgReceive + "Yes We Du";
23             byte[] sendData = Encoding.UTF8.GetBytes(megSend);
24             clentSocket.Send(sendData);
25             Console.WriteLine($"发送数据  {sendData}");
26         }
27 
28         Console.WriteLine($"关闭服务 收到关闭信息了");
29         Console.ReadKey();
30         clentSocket.Close();
31         serverSocket.Close();
32     }

客户端代码如下：

  String IP = "127.0.0.1";
            int port =8885 ;
 
            IPAddress ip = IPAddress.Parse(IP);  //将IP地址字符串转换成IPAddress实例
            ClientSocket = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);//使用指定的地址簇协议、套接字类型和通信协议
            IPEndPoint endPoint = new IPEndPoint(ip, port); // 用指定的ip和端口号初始化IPEndPoint实例
            ClientSocket.Connect(endPoint);  //与远程主机建立连接
 
 
            Console.WriteLine("开始发送消息");
            byte[] message = Encoding.ASCII.GetBytes("Connect the Server");  //通信时实际发送的是字节数组，所以要将发送消息转换字节
            ClientSocket.Send(message);
            Console.WriteLine("发送消息为:" + Encoding.ASCII.GetString(message));
            byte[] receive = new byte[1024];
            int length = ClientSocket.Receive(receive);  // length 接收字节数组长度
            Console.WriteLine("接收消息为：" + Encoding.ASCII.GetString(receive));
            ClientSocket.Close();  //关闭连接
