SettingsProviderConstructor

切换到手册
public SettingsProvider (string path, SettingsScope scopes, IEnumerable<string> keywords);

参数

path Settings 窗口中的设置路径。使用“/”作为分隔符。如果未提供,则最后一个标记将成为设置标签。
scope 设置范围。该范围确定设置显示的位置:在 Preferences 窗口中,还是在 Settings 窗口中。
keywords 要与用户搜索内容进行比较的关键字列表。当用户在 Settings 窗口的搜索框中输入值时,SettingsProvider.HasSearchInterest 会尝试将这些关键字与此列表进行匹配。
