Canceling async httpwebrequests

Question

I am making an app that will make several HttpWebRequest objects and downloading my html via the httpRequest.BeginGetResponse method. I get back the IAsyncRe

Answer 1

From the documentation for HttpWebRequest.Abort():

The Abort method cancels a request to a resource. After a request is canceled, calling the GetResponse, BeginGetResponse, EndGetResponse, GetRequestStream, BeginGetRequestStream, or EndGetRequestStream method causes a WebException with the Status property set to RequestCanceled.

So the behavior you describe is by design. I think you'll have to catch the exception, or else find some way of determining whether Abort was called before calling GetResponse, BeginGetResponse, EndGetResponse, GetRequestStream, BeginGetRequestStream, or EndGetRequestStream.
