    Retrieving HTTP Response Code

    How do I retrieve the HTTP Status code (ie 202, 404, etc) below? I am
    currently receiving the response text but unable to access the response
    status code.


    string strNewValue;

    string strResponse;

    // Create the request obj

    HttpWebRequest req = (HttpWebRequest ) WebRequest.Crea te(txtURL.Text) ;

    // Set values for the request back

    req.Method = "POST";

    //req.ContentType = "applicatio n/x-www-form-urlencoded";

    strNewValue = Server.HtmlDeco de(txtRequest.V alue.ToString() );

    //req.ContentLeng th = strNewValue.Len gth;

    req.

    // Write the request

    StreamWriter stOut = new StreamWriter (req.GetRequest Stream(),
    System.Text.Enc oding.ASCII);

    stOut.Write(str NewValue);

    stOut.Close();

    // Do the request to get the response

    StreamReader stIn = new StreamReader(re q.GetResponse() .GetResponseStr eam());

    strResponse = stIn.ReadToEnd( );

    stIn.Close();

    txtResponse.Val ue = strResponse;

      Hi Chris,

      HttpWebResponse rep = req.GetResponse ();
      HttpStatusCode c = rep.StatusCode;

      when getting the response you may have to deal with exceptions if the
      request is not successful so wrap it in a try-catch block.

          This works great, thank you. However, I would like to return the actual
          status code instead of the public enum HttpStatusCode representation. For
          example, I would to see 202 instead of Accepted.

          Is this possible?

              I have actually not tried this but I wonder if you can cast the StatusCode
              to an integer (or convert via System.Convert) . The MSDN docs mention that
              each status code maps to a numerical representation of the code:
