How to listen to specific IP address

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

Dns.GetHostAddresses queried with an empty string returns the local host adresses. You then can bind your server socket on a specific address (see Socket.Bind and IPEndPoint).
