after a long time search on google i found a way which work for all

 WebClient client = new WebClient();

            // Add a user agent header in case the
            // requested URI contains a query.

            client.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");

            Stream data = client.OpenRead("anyurl");
       
            StreamReader reader = new StreamReader(data);
            string s = reader.ReadToEnd();
           // Console.WriteLine(s);
            data.Close();
            reader.Close();
           lbl.Text= s.ToString();
