Application.Quit（）方法，未明确的流程 [英] Application.Quit() method failing to clear process

问题描述

我已经看到了很多从谷歌搜索这个返回的帖子，但没有一个解决方案在其中明确提到这件事对我来说。所以，我想我会尝试自己

I've seen a lot of posts returned from a Google search about this, but none of the solutions referenced in them clear this up for me. So, I thought I'd try myself.

这段代码后：

PowerPoint.Application powerPoint = new Microsoft.Office.Interop.PowerPoint.Application();
powerPoint.Visible = Office.MsoTriState.msoTrue;
Microsoft.Office.Interop.PowerPoint.Presentation ppt = null;enter code here

我可以发出ppt.Quit（）; 。命令和Powerpoint将关闭，没有进程保持运行状态

I can issue the ppt.Quit(); command and Powerpoint will close and no Process is left running.

但是，如果此代码后，我这样做：

However, if after this code I do this:

ppt = powerPoint.Presentations.Open(localCopyOfPPT,  
                                    Microsoft.Office.Core.MsoTriState.msoCTrue,
                                    Microsoft.Office.Core.MsoTriState.msoTriStateMixed,
                                    Microsoft.Office.Core.MsoTriState.msoTrue);
ppt.Close();
powerPoint.Quit();

然后，退出（）将无法工作。关于打开演示文稿的东西，即使我然后将其关闭，防止退出（）无法正常工作，它出现。

Then, the Quit() won't work. Something about opening the presentation, even if I then close it, prevents the Quit() from working, it appears.

任何人有关于我如何能得到应用程序的任何想法正确地退出呢？

Anybody have any thoughts about how I can get the application to quit correctlY?
