如何在后台实现UDP监听器？ （可用于log4net）

我想在后台运行这个UDPListener ：

 // launch this in a background thread private static void UDPListen() { IPEndPoint remoteEndPoint = new IPEndPoint(IPAddress.Any, 0) using( var udpClient = new UdpClient(10000)) { while (true) { var buffer = udpClient.Receive(ref remoteEndPoint); var loggingEvent = System.Text.Encoding.Unicode.GetString(buffer); // ... } } } 

我可以将它放在Task.Run()并在while()循环中运行吗？

这是我在阅读后进行设置的方法，并且有效。 非常简单！

异步方法

  private static void UDPListener() { Task.Run(async () => { using (var udpClient = new UdpClient(11000)) { string loggingEvent = ""; while (true) { //IPEndPoint object will allow us to read datagrams sent from any source. var receivedResults = await udpClient.ReceiveAsync(); loggingEvent += Encoding.ASCII.GetString(receivedResults.Buffer); } } }); } 

log4net config文件中的appender应该设置为：

同步方法

与上面的asynchronous方法一样，这也可以以非常类似的方式在synchronous方法中实现：

  private static void UDPListener() { Task.Run(() => { using (var udpClient = new UdpClient(11000)) { string loggingEvent = ""; while (true) { //IPEndPoint object will allow us to read datagrams sent from any source. var remoteEndPoint = new IPEndPoint(IPAddress.Any, 0); var receivedResults = udpClient.Receive(ref remoteEndPoint); loggingEvent += Encoding.ASCII.GetString(receivedResults); } } }); }
