Loading Documents

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

Visual Basic	Copy Code
Dim openPicker As New FileOpenPicker() openPicker.FileTypeFilter.Add(".pdf") Dim file As StorageFile = Await openPicker.PickSingleFileAsync() If file IsNot Nothing Then Dim stream As Stream = Await file.OpenStreamForReadAsync() pdfViewer.LoadDocument(stream) End If

Visual Basic

Copy Code

Dim openPicker As New FileOpenPicker()
openPicker.FileTypeFilter.Add(".pdf")

Dim file As StorageFile = Await openPicker.PickSingleFileAsync()
If file IsNot Nothing Then

    Dim stream As Stream = Await file.OpenStreamForReadAsync()

    pdfViewer.LoadDocument(stream)
End If

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);

}
