This event is raised each time an asynchronous file upload operation completes. Asynchronous file uploads are started by calling the erload:System.Net.WebClient.UploadFileAsync methods.
The System.Net.UploadFileCompletedEventHandler is the delegate for this event. The System.Net.UploadFileCompletedEventArgs class provides the event handler with event data.
