Socket exception in tcp listener

问题

I trying to run this code:

listener = new TcpListener(IPAddress.Any,port: 80);
            listener.Start();
            socket = listener.AcceptSocket();

but it throws the following exception: An attempt was made to access a socket in a way forbidden by its access permissions

What may be the reason?

回答1:

It might be forbidden to use a port below 1024 if you are not Administrator. Try a port like 8080 instead. see also Which port can i use for my socket?
