如何將IStorageItem項目轉換爲BitmapImage

Question

有誰知道如何將IStorageItem項目從CameraRoll轉換爲BitmapImage？

這裏是我的代碼：

 private async void Button_Click(object sender, RoutedEventArgs e) 
     { 

      StorageFolder picturesFolder = KnownFolders.CameraRoll; 

      IReadOnlyList<IStorageItem> itemsList = 
       await picturesFolder.GetItemsAsync(); 

      BitmapImage[] Images = new BitmapImage[itemsList.Count]; 
      int i = 0; 

      foreach (var item in itemsList) 
      { 
       if (item is StorageFolder) 
       { 
       } 
       else 
       { 
        i++; 

        //Images[i].SetSource(item); 

       } 
      } 
     }

在你else塊

else { 
    using (var stream = await item.OpenReadAsync()) 
    { 
     await Images[i].SetSourceAsync(stream); 
    } 
}
