如何使用 Open XML SDK 在 PPTx 中插入视频？

Question

我正在尝试创建一个基于 link (Working with presentation documents using the Open XML SDK 2.5) 的 PPTx 文件，并且能够创建包含图像、形状和标题的幻灯片文件。但我想将视频插入到新幻灯片中。有人可以帮我解决这个问题吗？

Answer 1

我从 Open XML SDK 2.5 Tool 得到了解决方案。以下是生成 C# 代码的步骤。

首先创建一个包含视频的 Powerpoint 演示文稿并保存。
使用打开 XML SDK 工具打开 PPTx 文件并单击 "Reflect Code"。

此操作将为您提供几千行 C# 代码。您可以直接使用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。
