问题描述
我尝试测试有以下code TCP连接。
I try to test TCP connection with the following code.
System.Threading.Thread t = new System.Threading.Thread(() => { using (TcpClient client = new TcpClient()) { client.Connect(ip, Convert.ToInt32(port)); } }); t.Start();
如何设置超时如果IP或端口是无效的?
How to set time out if the IP or port is invalid?
推荐答案没有内置的方式来做到这一点。我用下面的code对于很多我们的应用程序。在code绝不是原来的,但工作了好。请注意,您可能需要重试添加此功能...有时它返回false即使在服务器启动并运行。
There is no built in way to do this. I use the following code for many of our application. The code is by no means original but works out okay. Please note that you may have to add retries to this function... sometimes it returns false even when the server is up and running.
private static bool _TryPing(string strIpAddress, int intPort, int nTimeoutMsec) { Socket socket = null; try { socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); socket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.DontLinger, false); IAsyncResult result = socket.BeginConnect(strIpAddress, intPort, null, null); bool success = result.AsyncWaitHandle.WaitOne(nTimeoutMsec, true); return socket.Connected; } catch { return false; } finally { if (null != socket) socket.Close(); } }更多推荐
