这个例子只是简单实现了如何使用 Socket 类实现面向连接的通信。
注意:此例子的目的只是为了说明用套接字写程序的大概思路,而不是实际项目中的使用程序。在这个例子中,实际上还有很多问题没有解决,如消息边界问题、端口号是否被占用、消息命令的解析问题等。。
下面是两个程序的代码,(两个程序均为控制台程序)
先发服务端的(Server)完整代码如下:
引入命名空间:
- using System.Net.Sockets;
- using System.Net;
- using System.Threading;
完整代码如下:
- namespace SocketServer
- {
- class Program
- {
- private static byte[] result = new byte[1024];
- private static int myProt = 8885;
- static Socket serverSocket;
- static void Main(string[] args)
- {
-
- IPAddress ip = IPAddress.Parse("127.0.0.1");
- serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
- serverSocket.Bind(new IPEndPoint(ip, myProt));
- serverSocket.Listen(10);
- Console.WriteLine("启动监听{0}成功", serverSocket.LocalEndPoint.ToString());
-
- Thread myThread = new Thread(ListenClientConnect);
- myThread.Start();
- Console.ReadLine();
- }
-
-
-
-
- private static void ListenClientConnect()
- {
- while (true)
- {
- Socket clientSocket = serverSocket.Accept();
- clientSocket.Send(Encoding.ASCII.GetBytes("Server Say Hello"));
- Thread receiveThread = new Thread(ReceiveMessage);
- receiveThread.Start(clientSocket);
- }
- }
-
-
-
-
-
- private static void ReceiveMessage(object clientSocket)
- {
- Socket myClientSocket = (Socket)clientSocket;
- while (true)
- {
- try
- {
-
- int receiveNumber = myClientSocket.Receive(result);
- Console.WriteLine("接收客户端{0}消息{1}", myClientSocket.RemoteEndPoint.ToString(), Encoding.ASCII.GetString(result, 0, receiveNumber));
- }
- catch(Exception ex)
- {
- Console.WriteLine(ex.Message);
- myClientSocket.Shutdown(SocketShutdown.Both);
- myClientSocket.Close();
- break;
- }
- }
- }
- }
- }
以上是服务端(server)的完整代码。
客户端(Client)的完整代码如下:
引入命名空间:
- using System.Net;
- using System.Net.Sockets;
- using System.Threading;
完整代码:
- namespace SocketClient
- {
- class Program
- {
- private static byte[] result = new byte[1024];
- static void Main(string[] args)
- {
-
- IPAddress ip = IPAddress.Parse("127.0.0.1");
- Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
- try
- {
- clientSocket.Connect(new IPEndPoint(ip, 8885));
- Console.WriteLine("连接服务器成功");
- }
- catch
- {
- Console.WriteLine("连接服务器失败,请按回车键退出!");
- return;
- }
-
- int receiveLength = clientSocket.Receive(result);
- Console.WriteLine("接收服务器消息:{0}",Encoding.ASCII.GetString(result,0,receiveLength));
-
- for (int i = 0; i < 10; i++)
- {
- try
- {
- Thread.Sleep(1000);
- string sendMessage = "client send Message Hellp" + DateTime.Now;
- clientSocket.Send(Encoding.ASCII.GetBytes(sendMessage));
- Console.WriteLine("向服务器发送消息:{0}" + sendMessage);
- }
- catch
- {
- clientSocket.Shutdown(SocketShutdown.Both);
- clientSocket.Close();
- break;
- }
- }
- Console.WriteLine("发送完毕,按回车键退出");
- Console.ReadLine();
- }
- }
- }
编译成功后,先运行 服务端(server),再运行客户端(client)即可达到通信效果。
效果如下图:
该程序已在局域网测试通过。(192.168.X.X)
