HttpWebRequest throws an Exception if there is no internet connection.
You have handled the Exception using the catch block but there, you have also written throw which throws the exception again and if you haven't handled it into the calling method, your app will crash.
Either try removing throw from your catch block, or handle Exception again into a calling method.
Like
try
{
var result = Get("myUrl");
}
Catch(Exception ex)
{
//Handle it here too
}
