本文介绍了一个使用C#实现的Socket连接超时处理方法。通过创建Socket实例并设置超时回调，确保在网络不稳定或目标服务器未响应时能够及时通知应用程序。此外，还利用定时器来检查连接状态。

private void connect(string ipAdd,string port) { try { SocketAsyncEventArgs e=new SocketAsyncEventArgs(); m_clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); IPAddress ip = IPAddress.Parse(serverIp); int iPortNo = System.Convert.ToInt16(serverPort); IPEndPoint ipEnd = new IPEndPoint(ip, iPortNo); //m_clientSocket. e.RemoteEndPoint = ipEnd; e.UserToken = m_clientSocket; e.Completed+=new EventHandler<SocketAsyncEventArgs>(e_Completed); m_clientSocket.ConnectAsync(e); if (timer_connection != null) { timer_connection.Dispose(); } else { timer_connection = new Timer(); } timer_connection.Interval = 2000; timer_connection.Tick+=new EventHandler(timer_connection_Tick); timer_connection.Start(); } catch (SocketException se) { lb_connectStatus.Text = "Connection Failed"; MessageBox.Show(se.Message); } } private void e_Completed(object sender,SocketAsyncEventArgs e) { lb_connectStatus.Text = "Connection Established"; WaitForServerData(); } private void timer_connection_Tick(object sender, EventArgs e) { if (!m_clientSocket.Connected) { MessageBox.Show("Connection Timeout"); //m_clientSocket = null; timer_connection.Stop(); } }

这个范例示范了如何让 Socket 连线超时.
