我正在尝试使用 Visual Studio 在
C#Open XML SDK我创建的演示文稿包含一张幻灯片和一张 3 行 2 列的表格。
当我尝试打开该程序创建的 PowerPoint 演示文稿时，出现以下错误消息：
PowerPoint found a problem with content in test3.pptx.
PowerPoint can attempt to repair the presentation.
If you trust the source of this presentation, click Repair.
当我单击“修复”时，系统会显示另一条错误消息：
PowerPoint couldn't read some content in test3.pptx - Repaired and removed it.
Please check your presentation to see if the rest looks ok.
当我单击“确定”并检查演示文稿的内容时，它是空的。
我应该如何修改程序，以便用户可以毫无问题地打开演示文稿？

OpenOffice PPT 问题很有趣，我尝试了一些示例代码，并获得了以下工作示例，以使用 .NET 6 和 DocumentFormat.OpenXml 2.20（与您相同的版本）创建一个 powerpoint。
即使 Powerpoint 没有显示在视觉效果中（例如母版幻灯片、调色板等），您也需要提供相当多的层次结构，才能毫无怨言地打开它。删除一个部分将导致 Powerpoint 尝试（成功）修复演示文稿，这只是以编程方式再次添加该部分。
我没有调试您上面的代码，只是尝试了一下，可以重现您的问题。也许这篇文章中的代码可以帮助您：您可以使用它作为模板，然后只需将自定义布局添加到相应的幻灯片布局部分。玩得开心！
