答
没有函数可以从另一个Windows应用程序获取一个exe的路径.
您可以做的是，可以遍历程序文件目录以从第二个应用程序中找到第一个应用程序目录.
第二种选择是您可以创建第一个应用程序的注册表项，然后从第二个应用程序中找到注册表项.这将是更好的方法.
There is no function to get path of one exe from another windows application.
What you can do is you can iterate program files directory to find your first application directory from second application.
Second option is you can make a registry entry of first application and find entry in registry from second application.This will be better approach.
使用此属性
use this property
string path = Application.StartupPath ;
