解析Excel的路径 [英] Resolve path of Excel

问题描述

其实我想提出以下问题：

Actually I intended to ask the following question:

对于关键在于可执行   在定义的目录％PATH％，怎么能   我发现在这些目录中   它被发现的？

For an executable that lies in a directory defined in %PATH%, how can I find out in which of these directory it is found?

因为我需要使用Process.Run（...）C＃运行Excel，只是表示创先争优工作正常：WINDOWS似乎知道哪里可以找到它。不过，我需要提供相应的工作目录了。

because I need to run Excel from C# using Process.Run(...), and just indicating "Excel" works fine: Windows seems to know where to find it. However I need to provide the appropriate working directory, too.

但与此同时我发现，微软的Office是不是即使在％PATH％时，Windows显然解决它以另一种方式。

But in the meantime I found out that Microsoft Office is not even in the %PATH%, Windows apparently resolves it in another way.

所以，我怎么能使用或模仿从Windows此功能来获取包含Excel中的目录？

So how could I use or mimic this functionality from Windows to get the directory containing excel?

更新：此外鲁埃尔的建议，有一个直的方式实现这一目标？我知道，Windows是能够解析以某种方式的路径，所以我想重新使用这个功能，如果可能的。

Update: Besides the suggestion of Ruel, is there a straighter way to achieve this? I know that Windows is able to resolve the path in some way, so I'd like to reuse this functionality if possible.

你知道吗？

推荐答案

从注​​册表中读取它： HKLM \ SOFTWARE \微软\办公室\（版本）\ EXCEL \ InstallRoot 为版本也可以是10.0 11.0等，您可以通过检查，如果有一个子项检测到它 Excel中在里面

Fetch it from the registry: HKLM\SOFTWARE\Microsoft\Office\(VERSION)\Excel\InstallRoot for the VERSION it can be 10.0 11.0 etc. You can detect it by checking if there's a subkey Excel in it.
