Cancels a request to an Internet resource.
Assembly: System (in System.dll)
The 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.
The method will synchronously execute the callback specified to the BeginGetRequestStream or BeginGetResponse methods if the method is called while either of these operations are outstanding. This can lead to potential deadlock issues.
