某些 Powerpoint 演示文稿包含嵌入的电影。如何使用 C#（VSTO 或 Oficce COM Api）从演示文稿中导出电影（或获取电影文件的路径）？

这是执行此操作的简单演示：

不要忘记添加对 PowerPoint COM API 的引用
（Microsoft PowerPoint 12.0 对象库）。

using PowerPoint = Microsoft.Office.Interop.PowerPoint;
using Office = Microsoft.Office.Core;

然后你就可以像这样获取电影路径

    private void button1_Click(object sender, EventArgs e)
    {
        PowerPoint.Application app = new PowerPoint.Application();
        app.Visible = Office.MsoTriState.msoTrue;
        //open powerpoint file in your hard drive
        app.Presentations.Open(@"e:\my tests\hello world.pptx");

        foreach (PowerPoint.Slide slide in app.ActivePresentation.Slides)
        {
            PowerPoint.Shapes slideShapes = slide.Shapes;
            foreach (PowerPoint.Shape shape in slideShapes)
            {
                if (shape.Type == Office.MsoShapeType.msoMedia &&
                    shape.MediaType == PowerPoint.PpMediaType.ppMediaTypeMovie)
                {
                    //LinkFormat.SourceFullName contains the movie path 
                    //get the path like this
                    listBox1.Items.Add(shape.LinkFormat.SourceFullName);
                    //or use System.IO.File.Copy(shape.LinkFormat.SourceFullName, SOME_DESTINATION) to export them
                }
            }
        }
    }

我希望这会有所帮助。

关于 Steve 的评论，如果您只想要嵌入的电影，您只需像任何其他 zip 文件一样解压 .pptx 文件（例如使用 DotNetZip）并在此路径中查找嵌入视频（ [PowerPoint_文件名]\ppt\media)

Here is simple demo to do this:

don't forget to add reference to the PowerPoint COM API
(Microsoft PowerPoint 12.0 Object Library).

using PowerPoint = Microsoft.Office.Interop.PowerPoint;
using Office = Microsoft.Office.Core;

then you can get the movies path like this

    private void button1_Click(object sender, EventArgs e)
    {
        PowerPoint.Application app = new PowerPoint.Application();
        app.Visible = Office.MsoTriState.msoTrue;
        //open powerpoint file in your hard drive
        app.Presentations.Open(@"e:\my tests\hello world.pptx");

        foreach (PowerPoint.Slide slide in app.ActivePresentation.Slides)
        {
            PowerPoint.Shapes slideShapes = slide.Shapes;
            foreach (PowerPoint.Shape shape in slideShapes)
            {
                if (shape.Type == Office.MsoShapeType.msoMedia &&
                    shape.MediaType == PowerPoint.PpMediaType.ppMediaTypeMovie)
                {
                    //LinkFormat.SourceFullName contains the movie path 
                    //get the path like this
                    listBox1.Items.Add(shape.LinkFormat.SourceFullName);
                    //or use System.IO.File.Copy(shape.LinkFormat.SourceFullName, SOME_DESTINATION) to export them
                }
            }
        }
    }

I hope this will help.

[Edit:]

regarding Steve comment if you want just the embedded movies, you need just to unpack the .pptx file like any other zip file (e.g. using DotNetZip) and look for embedded videos in this path ([PowerPoint_fileName]\ppt\media)
