GET original error message with HttpWebResponse

[Jon Maz]

Hi All,

I am using a WebRequest & WebResponse to GET the contents of an aspx page as
a string (code below).

It's working fine, except that when the aspx page has an error on it, I want
to know precisely what the error was (ie I want to get the error message
that would be displayed if you were viewing the aspx page in a brower).

Instead I always get this error:
The remote server returned an error: (500) Internal Server Error
pointing to the line:
WebResponse myResponse = myRequest.GetResponse();

Can anyone tell me how I can GET the original error text returned to me?

Thanks,

JON

// Initialize the WebRequest.
WebRequest myRequest =
WebRequest.Create("http://localhost/PageWithError.aspx");

// Return the response.
WebResponse myResponse = myRequest.GetResponse();

// Convert the GET to a string and display it
StreamReader sr = new
StreamReader(myResponse.GetResponseStream(),System.Text.Encoding.Default);
string sBuffer;
sBuffer = sr.ReadToEnd();
sr.Close();
txtDisplayHtml.Text = sBuffer;

You mean the actual error page's content?

If a WebException is thrown because of a protocol error, its Response
property will give you access to actual response received from the web
server. Just make sure you check the Status property accordingly:

try {
// Do WebRequest
}
catch (WebException ex) {
if (ex.Status == WebExceptionStatus.ProtocolError) {
HttpWebResponse response = ex.Response as HttpWebResponse;
if (response != null) {
// Process response
}
}
}
