Question

I am making an API call to a REST service. The REST service returns an XML string that contains a user token if the password submitted is correct, or an XML string with data if it isn’t.

Here is an example if the password is incorrect:

<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
<authenticationResponse>
  <statusCode>403</statusCode>
  <errors>
    <error>
       ....
    </error>
  </errors>
  <timestamp>2011-03-31 22:45:03 GMT</timestamp>
</authenticationResponse>

With this code below, it appears .NET is translating this to an actual error. I still want it to read the XML data and ignore any error:

RequestData requestData = (RequestData)result.AsyncState;
HttpWebResponse response = 
                 (HttpWebResponse)requestData.Request.EndGetResponse(result);

How I can ignore the error but still create the stream to read the XML?

Catch WebException, check the exception status, read the response. See these questions for examples:

• Catching a specific WebException (550)
• WebException when reading a WebException's response stream
