如何使用Open XML SDK在PPTx中插入视频

Question

我正在尝试根据链接创建一个PPTx文件(使用Open XML SDK 2.5处理演示文稿文档(，并能够创建包含图像，形状和标题的幻灯片的文件。但是我想在新幻灯片中插入视频。有人可以帮我吗？

Answer 1

我从Open XML SDK 2.5 Tool获得了解决方案。下面是生成 C# 代码的步骤。

• 首先使用视频创建Powerpoint演示文稿并保存。
• 使用Open XML SDK工具打开PPTx文件，然后单击"反映代码"。

此操作将为您提供几千行 C# 代码。您可以直接使用该代码或进行一些修改以实现可重用性。我做了同样的事情，下面是我的最终输出。
