[Mono-dev] Tests for ParseRouteInfo

[Miguel de Icaza]

Hello,

Considering that we do not even have a test, I think it would be nice to
turn one of the samples on the git discussion into the test.   While not
100% robust, we could check that at least *one* of the interfaces has a
gateway, and perhaps make this into a soft failure for those that do not
actually have a network with a gateway when running the tests.

using System;

using System.Net;

using System.Net.NetworkInformation;


public class Test

{

    public static void Main()

    {

        DisplayGatewayAddresses();

    }


    public static void DisplayGatewayAddresses()

    {

        Console.WriteLine("Gateways");

        NetworkInterface[] adapters  =
NetworkInterface.GetAllNetworkInterfaces();

        foreach (NetworkInterface adapter in adapters)

        {

            IPInterfaceProperties adapterProperties =
adapter.GetIPProperties();

            GatewayIPAddressInformationCollection addresses =
adapterProperties.GatewayAddresses;

            Console.WriteLine(adapter.Description);

            if (addresses.Count >0)

            {

                foreach (GatewayIPAddressInformation address in addresses)

                {

                    Console.WriteLine("  Gateway Address
......................... : {0}",

                        address.Address.ToString());

                }

                Console.WriteLine();

            }

        }

    }

}
