We’re having a problem with an apparent limitation on the size of the response we’re able to retrieve from WebException.Response.

Here is the code:

WRequest = (HttpWebRequest)HttpWebRequest.Create (UploadURL);

if (!string.IsNullOrEmpty (deliveryDetails.Login))

{

WRequest.Credentials = new NetworkCredential (deliveryDetails.Login, deliveryDetails.Password);

}

WRequest.PreAuthenticate = true;

WRequest.UserAgent = "Ops Portal 1.0";

WRequest.Method = WebRequestMethods.Http.Post;

WRequest.AllowWriteStreamBuffering = true;

WRequest.Timeout = deliveryDetails.Timeout;

WRequest.ContentType = "text/xml";

System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding ();

byte[] theByteArray = encoding.GetBytes (theData.ToString ());

// Set the content length header to the size of the buffer.

WRequest.ContentLength = theByteArray.Length;

Stream tempStream = WRequest.GetRequestStream ();

tempStream.Write (theByteArray, 0, theByteArray.Length);

try

{

WResponse = (HttpWebResponse)WRequest.GetResponse ();

Stream theResponseStream = WResponse.GetResponseStream (); <- this produces the entire response stream intact

�/span>

}

catch (WebException wex)

{

WResponse = (HttpWebResponse)wex.Response;

if (WResponse != null)

{

int statusCode = (int)WResponse.StatusCode;

if (statusCode == 422) // Unprocessed Entity - this is treated the same as HttpStatusCode.OK

{

Stream theResponseStream = WResponse.GetResponseStream ();ß this appears to have a limit of 65K

StreamReader theReader = new StreamReader (theResponseStream, Encoding.UTF8);

TextWriter theWriter = new StreamWriter (theResponseFileName, true);

theWriter.Write (theReader.ReadToEnd ());

theWriter.Flush ();

theWriter.Close ();

�/span>

Is there a way to access the entire response when this type of exception is thrown?

Thanks!

As per http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.defaultmaximumerrorresponselength.aspx the error response is limited by default. You should be able to change the limit, though

Hope this helps.

Feroze, thank you so much.

Using your answer as my guide I was actually able to find:

In the web.config, after the system.web section, add the following:

<system.net>
<settings>
<httpWebRequest maximumErrorResponseLength="-1" />
</settings>
</system.net>

-1 means unlimited but you can use any value in there for the number of bytes.
