Try this...


System.Net.HttpWebRequest wr = (System.Net.HttpWebRequest)System.Net.WebRequest.Create("http://google.com/");

try
{
      System.Net.HttpWebResponse ws = (System.Net.HttpWebResponse)wr.GetResponse();
      MessageBox.Show( " ONLINE " );
}
catch
{
      MessageBox.Show( " OFFLINE " );
}
