加载图像后启动动画（显示）

Question

我使用它从uri加载图像，然后用.xaml页面中定义的动画（Storyboard）显示它：

var coverBitmap = new BitmapImage(urlToNewCover)
{
    CreateOptions = BitmapCreateOptions.None
};
coverBitmap.ImageOpened += async (s, args) => SetLookFromLoadedBitmap(coverBitmap, track);

    private void SetLookFromLoadedBitmap(BitmapImage coverBitmap, AudioTrack track)
    {
        SetCoverAndBackground(coverBitmap);
        SetLabelsByTrack(track);
        CoverImageSlideIn.Begin();
    }

    private void SetCoverAndBackground(BitmapImage bm)
    {
        ImgAlbumCover.Source = bm;
        ImgAlbumCoverCD.Visibility = Visibility.Collapsed;
        ChangeImageForBackground(bm);
    }

    private void ChangeImageForBackground(object s)
    {
        var wb = ImageHelpers.BlurBitmap((BitmapImage)s);
        var brush = new ImageBrush { ImageSource = wb };
        LayoutRoot.Background = brush;
    }

它正常工作，没关系。但是，当我使用隔离存储中的图像尝试它时，动画不会启动。图像刚刚显示。

var coverBitmap = new BitmapImage();
using (var isf = IsolatedStorageFile.GetUserStoreForApplication())
{
     if (isf.FileExists(track.AlbumArt.OriginalString))
     {
          using (var sourceFile = isf.OpenFile(track.AlbumArt.OriginalString, FileMode.Open, FileAccess.Read))
          {
              coverBitmap.SetSource(sourceFile);
          }
     }
 }
 SetLookFromLoadedBitmap(coverBitmap, track);

怎么了？我该如何解决？感谢

我的回答，嗯：）

string localFolderPath = ApplicationData.Current.LocalFolder.Path; Path.Combine( localFolderPath, track.AlbumArt.OriginalString );
