How to get list of photos to a ListElement of a xaml page?

Question

I m building a windows phone 8.1 application and using WinRT I need to capture a photo from my and need to display the captured photos as a list. I written the following code but I am unable to run it and I'm getting errors. Can any1 please correct this ?

Code:

private async void BtnCapturePhoto_Click(object sender, RoutedEventArgs e)     
{         
    BtnCapturePhoto.IsEnabled = false;

    var photoStorageFile = await cameraCapture.CapturePhoto();         
    var bitmap = new BitmapImage();

    await bitmap.SetSourceAsync(await photoStorageFile.OpenReadAsync());

    PhotoListView.Items.Add(bitmap);
    BtnCapturePhoto.IsEnabled = true;       
}

Errors:

Following are the errors when I run the application:

Error1

The best overloaded method match for 'Windows.UI.Xaml.Media.Imaging.BitmapSource.SetSourceAsync(Windows.Storage.Streams.IRandomAccessStream)' has some invalid arguments

Error2

Argument 1: cannot convert from 'void' to 'Windows.Storage.Streams.IRandomAccessStream' 

Error3

'object' does not contain a definition for 'OpenReadAsync' and no extension method 'OpenReadAsync' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) 

Answer 1

The problem is that photoStorageFile is a System.Object type in your code but it's a StorageFile in reality, so we first need to downcast it.

// Get the photoStorageFile as StorageFile not System.Object
StorageFile photoStorageFile = await cameraCapture.CapturePhoto() as StorageFile;

// Now we can properly set the source of the bitmapImage
using (IRandomAccessStream fileStream = await photoStorageFile.OpenAsync(Windows.Storage.FileAccessMode.Read))
{
     // Set the image source to the selected bitmap
     BitmapImage bitmapImage = new BitmapImage();

     await bitmapImage.SetSourceAsync(fileStream);
     bitmap.Source = bitmapImage;
}

this code should work
