我知道 Image.PropertyItems 数组保存有关加载图像的所有元数据信息。
BUT
你怎么知道例如ID = 20736 是例如的值每张幻灯片的 GIF 时间？
是否有所有已知 ID 的列表或其他内容？
我还没有找到任何东西。

是的，有一个列表in http://msdn.microsoft.com/de-de/library/ms534418.aspx the http://msdn.microsoft.com/de-de/library/ms534417.aspx 文档 http://msdn.microsoft.com/en-us/library/system.drawing.imaging.propertyitem.id.aspx:
