   Console::WriteLine( "Loopback IP address : {0}", IpAddressString );
}

public void PrintLoopbackAddress()
{
    // Gets the IP loopback address and converts it to a string.
    String ipAddressString = IPAddress.Loopback.ToString();

    Console.WriteLine("Loopback IP address : " + ipAddressString);
} //PrintLoopbackAddress
