How to get the IP Address of the LAN interface?

See more:

C#

I'm using this code:

strHostName = Dns.GetHostName();
IPHostEntry IpEntry = Dns.GetHostByName(strHostName);
IPAddress[] AddressList = IpEntry.AddressList;

I actually need one IP from this AddressList array (the LAN interface IP only)
Is there any way to know which IP in this array is the LAN interface IP ?


the program should still be working when my PC is connected to a LAN network and to the internet (throw a wireless adapter) at the same time...

waiting for your suggestions...

thanks :)
