Is there an equivalent to InternetCheckConnection in .Net? If not, why not
interop it?

Here's another alternative:

using System.Net;

HttpWebRequest request =
(HttpWebRequest)WebRequest.Create(@"http://www.microsoft.com");
An exception indicates that the site isn't reachable thus probably there is
no internet connection (ms site could be down as well, but that is not as
probable).

This is the check for network connectivity (in .NET 2.0):

System.Net.NetworkInformation.NetworkInterface.Get IsNetworkAvailable();

This will tell you only if you are connected to something (network, dialup,
wireless etc), not whether the internet is contactable. The best bet is to
try and do what you want to do and handle any exceptions, or try and open
something like google for microsoft to check for connectivity.

You can also handle events with network availability at
System.Net.NetworkInformation.NetworkChange.Networ kAvailabilityChanged
and you can ping webserver to check for connectivity too.
System.Net.NetworkInformation.Ping
