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.Create(txtURL.Text);

// Set values for the request back

req.Method = "POST";

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

strNewValue = Server.HtmlDecode(txtRequest.Value.ToString());

//req.ContentLength = strNewValue.Length;

req.

// Write the request

StreamWriter stOut = new StreamWriter (req.GetRequestStream(),
System.Text.Encoding.ASCII);

stOut.Write(strNewValue);

stOut.Close();

// Do the request to get the response

StreamReader stIn = new StreamReader(req.GetResponse().GetResponseStream());

strResponse = stIn.ReadToEnd();

stIn.Close();

txtResponse.Value = 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:
