Thread: HttpWebRequest.GetResponse() - Timeout exception

hi!
i'm programming an application, which relies on downloading stuff from the i-net.

either

Code:

new WebClient().DownloadString("http://.....")

or this version of it

Code:

                static private string Download(string url)
		{
			HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
			req.Method = "GET";
			WebResponse respon = req.GetResponse();
			Stream res = respon.GetResponseStream();

			string ret = "";
			byte[] buffer = new byte[1024];
			int read = 0;
			while ((read = res.Read(buffer, 0, buffer.Length)) > 0)
			{
				ret += Encoding.ASCII.GetString(buffer, 0, read);
			}
			return ret;
		}

are causing a timeout exception after a minute of application hang. looking at it in wireshark, you see that no request has been submitted. the trick is: this bug appears sporadically every 3-4 times downloading something.

plz help me

Just a small point, rather than manually having to loop through the received bytes, you could simply use a StreamReader instead. Example:

Code:

        private static String Download(String url)
        {
            String str = String.Empty;

            try
            {
                WebRequest request = WebRequest.Create(url);
                WebResponse response = request.GetResponse();
                Stream stream = response.GetResponseStream();
                StreamReader reader = new StreamReader(stream, Encoding.Default);
                str = reader.ReadToEnd();
                reader.Close();
                stream.Flush();
                stream.Close();
                response.Close();
            }
            catch { }

            return str;
        }

I had the exact same problem, and I fixed it by placing the WebResponse object in a using statement. I was not disposing of it. Just wanted to verify the fix by melle.
