Loading Documents

To open an existing PDF file you can use the LoadDocument or LoadDocumentAsync method by passing a stream to the file. To open a file selected by the user, complete the following code:

C#	Copy Code
FileOpenPicker openPicker = new FileOpenPicker(); openPicker.FileTypeFilter.Add(".pdf"); StorageFile file = await openPicker.PickSingleFileAsync(); if (file != null) { Stream stream = await file.OpenStreamForReadAsync(); pdfViewer.LoadDocument(stream); }

Copy Code

FileOpenPicker openPicker = new FileOpenPicker();
 
openPicker.FileTypeFilter.Add(".pdf");
StorageFile file = await openPicker.PickSingleFileAsync();
  if (file != null)
    {
       Stream stream = await file.OpenStreamForReadAsync();
       pdfViewer.LoadDocument(stream);
    }
