推荐答案

(在 Windows 上)查找程序安装路径的理想方法是从注册表中读取它.大多数安装程序会为该程序创建一个包含安装路径的注册表项.此密钥的确切位置以及它将命名的内容因相关程序而异.

The ideal way to find a program's installation path (on Windows) is to read it from the registry. Most installers will create a registry key for that program that contains the installation path. Exactly where this key is and what it will be named varies depending on the program in question.

要查找程序在注册表中是否有密钥，请打开regedit"并使用编辑 > 查找选项尝试使用程序名称查找密钥.如果存在这样的密钥，您可以使用 RegistryKey .NET Framework 库中的类.

To find if the program has a key in the registry, open 'regedit' and use the Edit > Find option to try and locate a key with the program name. If such a key exists, you can read it using the RegistryKey class in the .NET Framework library.

如果程序没有注册表项，那么另一个选择就是要求用户使用 OpenFileDialog 定位 .exe 文件，尽管这显然不理想.

If the program does not have a registry key then another option is just to ask the user to locate the .exe file with the OpenFileDialog, although this is obviously not ideal.
