Comentários

Esse evento é gerado sempre que uma operação de upload de arquivo assíncrona é concluída. Os uploads de arquivos assíncronos são iniciados chamando os UploadFileAsync métodos.

Esse UploadFileCompletedEventHandler é o representante deste evento. A UploadFileCompletedEventArgs classe fornece ao manipulador de eventos dados de evento.
