Примеры

В следующем примере показано влияние на потоки использования SetPrincipalPolicy метода для изменения основной политики домена приложения. Здесь также показан эффект использования SetThreadPrincipal метода для изменения субъекта, доступного для присоединения к потокам в домене приложения.

Комментарии

Задание этого значения будет эффективным только в том случае, если оно задано перед использованием Thread.CurrentPrincipal свойства . Например, если задать Thread.CurrentPrincipal для заданного субъекта (например, универсального субъекта), а затем использовать SetPrincipalPolicy метод , чтобы задать значение PrincipalPolicyWindowsPrincipal, текущий субъект останется универсальным субъектом.
