当我尝试监听端口时，请求的地址在其上下文中无效 [英] The requested address is not valid in its context when i try to listen a port

问题描述

我正在尝试使用网络连接到传感器，传感器的ip是端口3000上的192.168.2.44；

I am trying to connect to a sensor using network, the sensor's ip is 192.168.2.44 on port 3000;

我的代码:

byte[] byteReadStream = null; // holds the data in byte buffer
IPEndPoint ipe = new IPEndPoint(IPAddress.Parse("192.168.2.44"), 3000);//listen on all local addresses and 8888 port
TcpListener tcpl = new TcpListener(ipe);
while (true)
{
    //infinite loop
    tcpl.Start(); // block application until data and connection
    TcpClient tcpc = tcpl.AcceptTcpClient();
    byteReadStream = new byte[tcpc.Available]; //allocate space
    tcpc.GetStream().Read(byteReadStream, 0, tcpc.Available);
    Console.WriteLine(Encoding.Default.GetString(byteReadStream) + "\n");
}

但是当我运行这段代码时，我得到了这个错误:

But when i run this code i got this error:

请求的地址在其上下文中无效

The requested address is not valid in its context

推荐答案

使用IPAddress.Any进行收听.这似乎是您的目标:

Use IPAddress.Any to listen. This seems to be your goal:

//listen on all local addresses

您指定的监听地址由于某种原因无效.无需指定数字地址.

The listening address you have specified is invalid for some reason. There is no need to specify a numeric address.
