我构建了一个 Windows 服务（在 Visual Studio 2015 中），我需要用户选择要安装的目录，但在安装时我需要在提供的目录中添加一个子文件夹。通常我使用System.Reflection.Assembly.GetExecutingAssembly().Location 获取安装目录，但我无法更改它。例如，我可以在BeforeInstall 方法中更改任何方法或属性吗？

我花了几天时间搜索，但实际上很容易。 为此，您需要
View->File System。application folder并选择Add->Folder。application folder 移到您的新文件夹中。差不多了。
这里有一些代码可以帮助您使用一个安装程序两次安装相同的服务。安装程序设置服务恢复模式、服务权限、访问权限、重写一些配置文件并启动这两个服务。卸载部分卸载这两个服务。
