我有一个可执行文件的名称，如cmd.exe的，并需要解决它的完全合格的路径。我知道这个exe出现在PATH环境变量中列出的目录之一。有没有办法解决，而不进行解析和测试每个目录在PATH变量的完整路径？基本上我并不想这样做：

I have an executable name, like "cmd.exe" and need to resolve it's fully-qualified path. I know the exe appears in one of the directories listed in the PATH environment variable. Is there a way to resolve the full path without parsing and testing each directory in the PATH variable? basically I don't want to do this:

foreach (string entry in Environment.GetEnvironmentVariable("PATH").Split(';'))
	...

必须有一个更好的办法，对吧？

There has to be a better way, right?

推荐答案

这似乎是这样做已经是一个pretty的好办法 - 因为据我所知，通过在 PATH 环境变量是Windows一样反正当它试图解决的路径。

This seems like a pretty good way of doing it already -- as far as I know, searching through the directories in the PATH environment variable is what Windows does anyway when it's trying to resolve a path.
