Check with the following code:

try
            {
               if (!url.Contains("http://")) url = "http://" + url;
                WebRequest req = WebRequest.Create(url);

                WebResponse res = req.GetResponse();

                Console.WriteLine("Url Exists");
            }
            catch (WebException ex)
            {
                Console.WriteLine(ex.Message);
                if (ex.Message.Contains("remote name could not be resolved"))
                {
                    Console.WriteLine("Url is Invalid");
                }
            }
