从ppt演示文稿中选择某些幻灯片并粘贴excel图表

Question

我有以下代码来打开工作表，复制一个图表，打开演示文稿并将其粘贴。

对于一张图表和一张幻灯片，它工作正常，但是在XLSM中有8张图表，因此PPTX中有8张幻灯片，我不知道如何选择第二张图表并将其粘贴到第二张或第三张幻灯片中介绍。

使用PowerPoint.Slide curSlide = pptApp.ActiveWindow.View.Slide; 它选择当前幻灯片或幻灯片1。

使用以下代码解决了问题：

p = pptApp.ActivePresentation; 
slides = p.Slides; 
slides[3].Select(); 
Ppt.Slide slide3 = pptApp.ActiveWindow.View.Slide;
