HttpWebRequest Class - Process Exception Message

[iana_kosio]

Hi,

I am using HttpWebRequest class to communicate with remote server. In some cases the server would return 5xx status code which results in HttpWebRequest object throwing an exception. I, however, still need to access the response stream from the server as it contains information that I need. Any ideas how I can do that?

Thanks,
Konstantin

try
{
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://localhost/myUrl");
myRequest.Method = "GET";
WebResponse response = myRequest.GetResponse();
//If the server returns 5xx status code the next statement executed will be in the catch block
//Nevertheless, I still need the response stream from the server
Stream responseStream = response.GetResponseStream();
}
catch (System.Exception exc)
{
//Process exception
//How can I access the response stream from here?
}

Hi Konstantin,

By default WebRequest will throw an exception. You have to handle the
WebException and use the resulting ex.Response of it to read from to get the
full content from the server.

// *** Return the Response data
HttpWebResponse WebResponse = null;
try
{
WebResponse = (HttpWebResponse) loHttp.GetResponse();
}
catch(WebException ex)
{
if (ex.Status == WebExceptionStatus.ProtocolError)
WebResponse = (HttpWebResponse) ex.Response ;
}

Hope this helps,
