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);
}
