Примеры

В следующем примере кода пользователю предоставляется возможность поиска профилей с помощью FindProfilesByUserName методов и. FindInactiveProfilesByUserNameThe following code example allows a user to search for profiles using the FindProfilesByUserName and FindInactiveProfilesByUserName methods. Пользователь может передать ProfileInfoCollection возвращаемые find методом методы DeleteProfiles в метод для удаления связанных профилей из источника данных.The user can pass the ProfileInfoCollection returned by the find methods to the DeleteProfiles method to delete the associated profiles from the data source.
