c# - 将 PowerPoint 演示文稿中的所有声音静音

Question

我正在以幻灯片模式从我的桌面应用程序中打开一个 ppt 文件。我想将所有嵌入或与演示文稿链接的声音静音(如果存在)。如何将演示文稿静音？

我正在使用以下代码打开演示文稿。

Process pptProcess;
string appPath = "C:\\Program Files\\Microsoft Office\\Office14\\powerpnt.exe";
string fileName = "D:\\Documents\\SamplePpt.pptx";
pptProcess = Process.Start(appPath, "/s " + fileName);

There's nothing like this in the object model.

PowerPoint basically hands the sounds off to Windows to play, it doesn't play them itself.

You might be able to make a copy of the PPT, visit each slide and shape to determine whether it has a transition/animation sound and if so, whether it's one you want to allow or not; if not, remove it.
