作为后续行动这一点，我也想知道是否有任何的API，帮助创建应用程序特定设置。
As a follow up to this, I'm also wondering if there are any APIs that aid in creating application specific settings.
除非有人建议我，这是不对的，我想保存的东西无论是在 HKCU ...或HKLM /软件/ MyCompanyName / MyAppName /键的注册表，或％APPDATA \ MyCompanyName \ MyAppName \ someTypeOfSettingsFile 。
Unless someone advises me that this is wrong, I'd like to save stuff either in HKCU... or HKLM/Software/MyCompanyName/MyAppName/Key for the registry, or in %APPDATA\MyCompanyName\MyAppName\someTypeOfSettingsFile.
由于这些似乎常用于这样的设置，我认为净可以很容易地存储在这些地方设置。有一个简单的高层次的API，可以净给我来读写设置这些常见的位置？

应避免注册表。
的app.exe.config的位置和 user.config文件将不同根据 如何安装应用程序。对于 一个基于Windows窗体的应用 复制到本地计算机上， app.exe.config将驻留在同一 目录中的基本目录 应用程序的主执行文件， 和user.config将驻留在 位置指定的 Application.LocalUserAppDataPath 属性。用于安装的应用程序 借助于的ClickOnce的，这两个 文件将驻留在的ClickOnce 数据目录下 ％InstallRoot％\ Documents和 Settings \用户名\ Local设置。
The location of the app.exe.config and user.config files will differ based on how the application is installed. For a Windows Forms-based application copied onto the local computer, app.exe.config will reside in the same directory as the base directory of the application's main executable file, and user.config will reside in the location specified by the Application.LocalUserAppDataPath property. For an application installed by means of ClickOnce, both of these files will reside in the ClickOnce Data Directory underneath %InstallRoot%\Documents and Settings\username\Local Settings.
