具有多个客户端的TCP服务器

我正在研究TCP服务器/客户端应用程序。

我的问题是：

我的服务器应用程序启动一个新线程并阻止它，直到接受了listenforClient方法的连接

但是，如何在多个客户端连接到我的服务器时管理连接，并且他们同时请求不同的东西我如何管理客户端1获取其需要的信息以及客户端2的相同信息。

它是multithreading的，因此多个客户端可以连接，但我如何处理请求。 我不想把所有东西放在1方法中。

提前致谢

private void serverstart() { this.tcplistener = new TcpListener(IPAddress.Any, 49151); this.listenThread = new Thread(new ThreadStart(ListenForClients)); this.listenThread.Start(); } private void ListenForClients() { this.tcplistener.Start(); while (true) { //blocks until a client has connected to the server TcpClient client = this.tcplistener.AcceptTcpClient(); // here was first an message that send hello client // /////////////////////////////////////////////////// //create a thread to handle communication //with connected client Thread clientThread = new Thread(new ParameterizedThreadStart(HandleClientComm)); clientThread.Start(client); } } private void HandleClientComm(object client) { TcpClient tcpClient = (TcpClient)client; NetworkStream clientStream = tcpClient.GetStream(); byte[] message = new byte[4096]; int bytesRead; while (true) { bytesRead = 0; try { //blocks until a client sends a message bytesRead = clientStream.Read(message, 0, 4096); } catch { //a socket error has occured break; } if (bytesRead == 0) { //the client has disconnected from the server break; } //message has successfully been received ASCIIEncoding encoder = new ASCIIEncoding(); bufferincmessage = encoder.GetString(message, 0, bytesRead); if (System.Text.RegularExpressions.Regex.IsMatch(bufferincmessage, Properties.Settings.Default.REQLogin, System.Text.RegularExpressions.RegexOptions.IgnoreCase)) { bufferincmessageresult = bufferincmessage.Split('^'); nickname_Cl = bufferincmessageresult[1]; password_Cl = bufferincmessageresult[2]; getuserdata_db(); login(); byte[] buffer = encoder.GetBytes(inlogmessage); clientStream.Write(buffer, 0, buffer.Length); clientStream.Flush(); } } }

您的客户端将以不同的线程发送，因此它们不会相交。 您只需添加“DispatchMethod”之类的内容即可处理您的消息。

 using System.Text.RegularExpressions; ... if (Regex.IsMatch(bufferincmessage, Properties.Settings.Default.REQLogin, RegexOptions.IgnoreCase)) { ... } else if (Regex.IsMatch(bufferincmessage, /*some of your command1*/, RegexOptions.IgnoreCase)) { ... } else if (Regex.IsMatch(bufferincmessage, /*some of your command1*/, RegexOptions.IgnoreCase)) { ... }
