我正在尝试使用OpenXML构建PowerPoint演示文稿时构建目录。这将需要具有到幻灯片的超链接。 我使用了Open XML生产力工具来尝试找出要使用的代码，并查看此question以及其中引用的链接。
我用于测试的powerpoint文件包含一些幻灯片，但是为了测试代码，应该在文本框的开头添加一个幻灯片，并在文本框中添加两行文本，分别引用幻灯片2和3。
最后打开文件时，出现以下错误 PowerPoint发现中的内容有问题。 PowerPoint可以尝试修复演示文稿。
如果我尝试修复，则有两行的文本框在那里，但整个演示文稿中的所有格式均已更改，并且文本未链接到其他幻灯片。
这是我正在使用的代码
