Question

On my server, under advanced TCP/IP settings I have two IP addresses added.
My question is, how can I specify that I want to listen to the first or second IP? Is there a way to obtain all IP addresses on my machine via .NET and select one to listen to?

Any help would be appreciated. I hope my question is clear.

Thanks.

The TCPListener in System.Net.Sockets accepts an IP and a port on construction:

  Int32 port = 13000;
  IPAddress localAddr = IPAddress.Parse("127.0.0.1");

  // TcpListener server = new TcpListener(port);
  server = new TcpListener(localAddr, port);

The full MSDN article is here and also look at the TCPClient
