For example to get local ip address I use:
string myHost = System.Net.Dns.GetHostName();
string myIP = System.Net.Dns.GetHostEntry(myHost).AddressList[0].ToString();

+1 - a web request is the ONLY way to do it. You need to get into the internet to know whether you are behind 1 or more NAT devices. SO, a web based API call to some external server returning your IP is it.

You could try the following:
IPHostEntry IPHost = Dns.GetHostByName(Dns.GetHostName());
The following is a use example:
lblStatus.Text = "My IP address is " +
IPHost.AddressList[0].ToString();
Edit: ha, ha, derek, beat me to it! ;P

Sadly, this may not give you the external ip, simply because the ip you get is still the one assigned to you by your local DNS - which may be on your little NAT router.
