Re: Internet Accessible?

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

Here's another alternative:

using System.Net;

HttpWebRequest request =
(HttpWebRequest )WebRequest.Cre ate(@"http://www.microsoft.c om");


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).

Re: Internet Accessible?

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

System.Net.Netw orkInformation. NetworkInterfac e.GetIsNetworkA vailable();

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.

RE: Internet Accessible?

You can also handle events with network availability at
System.Net.Netw orkInformation. NetworkChange.N etworkAvailabil ityChanged
and you can ping webserver to check for connectivity too.
System.Net.Netw orkInformation. Ping
