Powerpoint编辑如何将一种形状从一张幻灯片复制到另一张幻灯片 [英] Powerpoint editing how to copy one shape from one slide to another

问题描述

我是c＃编程的新手，但是整个ms office库都让我感到困惑。我想从一张幻灯片3复制一个文本框，然后将其粘贴到幻灯片2中。我按照我发现的页面上的说明进行操作：如何在c＃中将形状从一张幻灯片复制到另一张幻灯片？

I'm a newbie in c# programming and I'm just confounded by the entire ms office library. I want to copy a textbox from one slide 3 and paste it in slide 2. I followed instruction from a page I found: How can I copy shapes from one slide to another slide in c#?

presentation.Slides[3 + 1].Shapes[2 + 1].Copy();
presentaiton.Slides.Paste(2 + 1);

但是出现错误信息并说：由于剪贴板为空或包含与幻灯片不兼容的东西而无法粘贴。我看不到剪贴板是空的。实际上，我可以将其粘贴在单词上，然后查看其含义-一次是一张空白图片，另一张是幻灯片中的灰色阴影。所以总的来说，我有两个问题：如何知道应该复制哪种阴影以及为什么c＃不允许复制形状并将其粘贴到另一个阴影中？

But error message emerges and says: cannot paste because the clipboard is empty or contains things incompatible with the slide. I don't see the clipboard is empty. In fact I can paste it on the word and see what it was - One time it was a blank picture and another a gray shade which are in that slide. So in general I have two problem: how to know which shade I should copy out and why doesn't c# allow copying a shape and paste it in another?

我想知道是否有完整的或官方的库或教程可以在c＃上使用powerpoint进行操作，而不是ms网站上完全没有用的。

Also I'm wondering if there is a complete or official library or tutorial for operating on powerpoint in c# other than that on ms website which is completely useless.

推荐答案

在vba中，您可以这样做：

In vba it, you'd do it like this:

ActivePresentation.Slides(2).Shapes(3).Copy
ActivePresentation.Slides(3).Shapes.Paste

复制幻灯片2上的第三个形状到幻灯片3

This'd copy the third shape on slide 2 to slide 3
