Question

I need to get the actual local network IP address of the computer (e.g. 192.168.0.220) from my program using C# and .NET 3.5. I can’t just use 127.0.0.1 in this case.

How can I accomplish this?

In How to get IP addresses in .NET with a host name by John Spano, it says to add the System.Net namespace, and use the following code:

//To get the local IP address  string sHostName = Dns.GetHostName ();  IPHostEntry ipE = Dns.GetHostByName (sHostName);  IPAddress [] IpA = ipE.AddressList;  for (int i = 0; i < IpA.Length; i++)  {      Console.WriteLine ("IP Address {0}: {1} ", i, IpA[i].ToString ());  }
