public string DestinationFileName { get; }
The download operation destination file name.
This is the same value as the destinationFileName parameter passed to DownloadFileAsync if this method was called to initiate the download. If GetDownloadStreamAsync was called to initiate the download, then the value of this property is null (Nothing in VB).
