Note: This property is new in the .NET Framework version 2.0.
Gets the server reply to a data upload operation that is started by calling an UploadFileAsync method.
Namespace: System.Net Assembly: System (in system.dll)
You should check the Error and Cancelled properties to determine whether the upload completed. If the Error property's value is an Exception object or the Cancelled property's value is true, the asynchronous operation did not complete correctly and the Result property's value will not be valid.
