Abort request wp7
If I abort the request I have a WebException. How I can check if request is aborted?
// if (asynchronousResult.AsyncState !="Aborted" ) {
HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asynchronou开发者_Go百科sResult);//WebException if aborted
Stream streamResponse = response.GetResponseStream();
StreamReader streamRead = new StreamReader(streamResponse);
do_after(streamRead.ReadToEnd());
streamResponse.Close();
streamRead.Close();
response.Close();
// }
try
{
HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asynchronousResult);//WebException if aborted
}
catch(WebException e)
{
if(e.Status == WebExceptionStatus.RequestCanceled)
{
//WORK
}
}
From Documentation:
The Abort
method cancels a request to a resource. After a request is canceled, calling the BeginGetResponse
, EndGetResponse
, BeginGetRequestStream
, or EndGetRequestStream
method causes a WebException
with the Status
property set to RequestCanceled
.

You should wrap EndGetResponse in a try-catch block. If a web request is aborted you are facing an unexpected flow, therefore exceptions are the best way to handle this.
