        string htlm = client.DownloadString(url);

Answer 1

I found this question DownloadString timed out . It is identical to your question. But in this case you should use something like

    oClient.Headers.Add("user-agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:30.0) Gecko/20100101 Firefox/30.0");

instead of

 oClient.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705;)");
