c# - Launch file from isolated storage in Windows Phone 8.1 -

• This separate storage
• Launched with the default app

• I have done all the code very well, even opening the ".pdf, .txt" document Save to, but its contents are not visible, it remains empty In case of ".docx", I get this message:

    "Documents are damaged. Obtained and could not be opened " 

  Please see below my code:

    string file =" abc.pdf "; Uri Uri = new Uri ("https://www.abc.com/abcd/getDocument"); Webclient wc = new webclient (); Wc.OpenReadAsync (URI); Wc.OpenReadCompleted + = wc_OpenReadCompleted; Async zero wc_OpenReadCompleted (object sender, OpenReadCompletedEventArgs e) {byte [buffer = new byte [e.Result.Length]; E.Result.ReadAsync (wait for buffer, 0, (int. Buffer)); Using (IsolatedStorageFile storageFile = IsolatedStorageFile.GetUserStoreForApplication ()) using {(IsolatedStorageFileStream Section = storageFile.OpenFile (file, FileMode.Create)) wait {stream.WriteAsync (buffer, 0, buffer.Length); Stream.Flush (); }} StorageFolder Local = Windows.Storage.ApplicationData.Current.LocalFolder; StorageFile pdffile = Wait for the local. GetFileAsync (file); // Launch the PDF file awaiting Windows.System.Launcher.LaunchFileAsync (pdffile); }
