Loading an image file in WinRT

Question

I have a WinRT project, and am getting an error when trying to preview an image. I have set capabilities to allow access to the Pictures library, and am using the following code:

 var file = await Windows.Storage.KnownFolders.PicturesLibrary.GetFileAsync(path);
 var fileStream = await file.OpenAsync(Windows.Storage.FileAccessMode.Read);
 var img = new BitmapImage();
 img.SetSource(fileStream);

This error occurs on the first line:

A first chance exception of type 'System.Runtime.InteropServices.COMException' occurred in mscorlib.dll

Additional information: Error HRESULT E_FAIL has been returned from a call to a COM component.

I've tried other operations, such as folder.GetFilesAsync() with the same error. Is there another or capability that I need to allow this functionality to work correctly?

EDIT:

Based on @L.T.s answer, I tried some other capabilities. The following gives me the same error:

var folder = KnownFolders.PicturesLibrary;            
var files = await folder.GetFilesAsync();

However (obviously, providing I provide the Music capability) this does not:

var testfolder = KnownFolders.MusicLibrary;
var files = await testfolder.GetFilesAsync();

I don't doubt that this it something specific to my Pictures library, but I have no idea what that could be.

Answer 1

If your cost is just to preview an image. You can use this

        Uri uri = new Uri("ms-appx:///Assets/test.png");
        BitmapImage bitmap = new BitmapImage(uri);
        Image image = new Image();
        image.Source = bitmap;

and add the image to a canvas. But you need to add your test.png to your projects assets first or you can change the Uri to the location of your test image.
