SettingsProvider Constructor

Объявление

public SettingsProvider(string path, SettingsScope scopes, IEnumerable keywords);

Параметры

path	Путь к настройкам в окне настроек. В качестве разделителя используется «/». Последний токен становится меткой настроек, если он не указан.
scope	Объем настроек. Область действия определяет, где отображается настройка: в окнах «Настройки» или «Настройки».
keywords	Список ключевых слов для сравнения с тем, что ищет пользователь. Когда пользователь вводит значения в поле поиска в окне настроек, SettingsProvider.HasSearchInterest пытается сопоставить эти ключевые слова с этим списком.

Описание

Создает нового поставщика настроек.
