这张照片有什么问题？
不是显示史前植物的精美图片，而是显示位图位置的字符串！
这是 XAML（片段）：
<DataTemplate x:Key="YoungPicCell">
<StackPanel Orientation="Horizontal">
<Image Height="200" Width="200" Stretch="None" Source="{Binding Path=YoungPicBmp}" />
</StackPanel>
</DataTemplate>
文件名（和其他数据）在运行时从 XML 文件加载。
这是在运行时从 XML 文件加载的数据：

public string Name { get; set; }
