推荐答案

从我可以在MSDN上看到，presentationDocument从OpenXML的SDK来了，是吗？如果是这样，这仅支持使用presentationML格式Ope​​nXML文档。

From what I can see on MSDN, PresentationDocument is coming from the OpenXML SDK, yes? If so, this only supports OpenXML documents using the PresentationML format.

在你的文件中的 .PPT 扩展（而不是 .PPTX ）表明它是老的二进制格式，不被支持。作为测试，该文件的副本保存为 .PPTX ，看看，如果这个工程。

The .ppt extension on your file (rather than .pptx) suggests it is the older binary format, which isn't supported. As a test, save a copy of the file as a .pptx and see if this works.

您已经在使用注释提到的Aspose成功。阅读Aspose幻灯片不支持旧的二进制格式，这将给予证明我的理论。

You've mentioned success using Aspose in a comment. Aspose Slides does support the older binary format, which would lend evidence to my theory.
