Check network connection status using C#.net

Check network connection status using C#.net
Simple way to check network connection check the code below.
using System;
using System.Runtime.InteropServices;
//Creating the extern function...
private extern static bool InternetGetConnectedState(out int Description, int ReservedValue);
//Creating a function that uses the API function...
public static bool IsConnectedToInternet()
int Desc;
return InternetGetConnectedState(out Desc, 0);
//Use function
if (IsConnectedToInternet())
MessageBox.Show("Netwok Connection Up");
MessageBox.Show("Sorry! Network Connection down.");

Hi, thanks.

I found there is a way to get a lot information about network connections with managed code.
Use the framework classes
in [System.Net.NetworkInformation]
i.e. NetworkInterface.

"The GetAllNetworkInterfaces method returns an array that contains one instance of this class for each network interface on the local computer."
