我在滚动查看器内的堆栈面板中水平添加了 10 张图像。当用户滑动页面时,滚动查看器停止在某个位置,如果滚动停止在 &th 图像我想获取图像的名称。如何得到它?

      for (int i = 0; i <= 59; i++)
        {

  Uri uri = new  Uri("http://d1mu9ule1cy7bp.cloudfront.net/2012/media/catalogues/47/pages/p_" + i + "/thump.jpg");
            ImageSource img1 = new BitmapImage(uri);
            Image rect = new Image { RenderTransform = new TranslateTransform() };

            rect.Source = img1;

            stack.Children.Add(rect);

        }

XAML:

<ScrollViewer HorizontalContentAlignment="Left" HorizontalAlignment="Left" Name="scroll" VerticalScrollBarVisibility="Disabled" HorizontalScrollBarVisibility="Visible">

        <StackPanel Name="stack" Width="Auto" Orientation="Horizontal" HorizontalAlignment="Left"  >

    </StackPanel>
    </ScrollViewer>

假设您的图像大小相同,您可以通过查看HorizontalOffsetScrollViewer 来计算。
