The following code gives you the first Default Gateway:
NetworkInterface card = NetworkInterface.GetAllNetworkInterfaces().FirstOrDefault();
if (card == null)
return null;
GatewayIPAddressInformation address = card.GetIPProperties().GatewayAddresses.FirstOrDefault();
if (address == null)
return null;
return address.Address;

In the windows TCP/IP 4 Properties you can press the "Advanced" button. Then you can add multiple "Default gateway's". – Martijn van Put Mar 12 '14 at 21:05
