If WebRequest.Abort() before BeginGetResponse-CallBack?

Hi When I send BeginGetResponse() to the server, then WebRequest.Abort() before BeginGetResponse-CallBack, the WebReuest is correct aborted, but the BeginGetResponse-CallBack still runs a few later. So, it will get a WebException. Because cann't call EndGetResponse(EndGetResponse was called in BeginGetResponse-CallBack) after WebRequest.Abort() How to do that if WebRequest.Abort() before BeginGetResponse-CallBack? Thanks

I got these



   at System.Net.HttpWebRequest.CheckFinalStatus()
   at System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult)
   at Pe.MainForm.RespCallback(IAsyncResult ar) in c:\vs\pe\p.cs:line 972
   at System.Net.LazyAsyncResult.InvokeCallback()
   at System.Net.LazyAsyncResult.InvokeCallback(Boolean completedSynchronously)
   at System.Net.HttpWebRequest.SetResponse(Exception E)
   at System.Net.ConnectionReturnResult.SetResponses(ConnectionReturnResult returnResult)
   at System.Net.Connection.StartConnectionCallback(Object state, Boolean wasSignalled)

OR

   at System.Net.HttpWebRequest.CheckFinalStatus()
   at System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult)
