Is there a way to extract the message from WebException?

Question

Is there a way to extract the text that is being sent back as part of the WebException that occurs can occur with a HttpWebResponse? I can get all of the header information but there is a custom message being returned with the 400 or 401 response that I would like to get if possible. I am currently handling the exception in my test like this:

        var ex = Assert.Throws<WebException>(() =>
        {
            HttpWebResponse response = Utils.GetRawResponse(url);
        });

        Assert.Contains("401", ex.Message);

Here is how am getting the response:

public static HttpWebResponse GetRawResponse(string requestURL)
{

    HttpWebRequest request = WebRequest.Create(requestURL) as HttpWebRequest;

    HttpWebResponse response = request.GetResponse() as HttpWebResponse;


    return response;

}

And this works, but does not have the custom message.

Top hopefully be a little more clear am am referring to the message text in the bottom of the screenshot.:

With Gusmans reminder I created a method to extract the response from the WebException:

    public static string ParseExceptionRespose(WebException exception)
    {
        string responseContents;
        Stream descrption = ((HttpWebResponse)exception.Response).GetResponseStream();

        using (StreamReader readStream = new StreamReader(descrption))
        {
            responseContents = readStream.ReadToEnd();
        }

        return responseContents;

    }
