I just created a small program for detecting internet connection on computer, that will be use for uploading of local database to central server
Here is the sample code
using System.Net;
public static bool CheckForInternetConnection()
{
try
{
using (var client = new WebClient())
using (var stream = client.OpenRead("http://google.com.ph"))
{
return true;
}
}
catch
{
return false;
}
}
