AppDomain.SetPrincipalPolicy(PrincipalPolicy) Метод

Определение

Указывает, как участники и объекты удостоверений должны присоединяться к потоку, если поток пытается выполнить привязку к участнику при выполнении в этом домене приложения.Specifies how principal and identity objects should be attached to a thread if the thread attempts to bind to a principal while executing in this application domain.

policy
PrincipalPolicy

Исключения

Предпринята попытка выполнения операции с выгруженным доменом приложения.The operation is attempted on an unloaded application domain.

Примеры

В следующем примере показано воздействие на потоки с использованием SetPrincipalPolicy метода для изменения основной политики домена приложения.The following example shows the effect on threads of using the SetPrincipalPolicy method to change the principal policy of the application domain. Он также показывает результат использования SetThreadPrincipal метода для изменения субъекта, доступного для присоединения к потокам в домене приложения.It also shows the effect of using the SetThreadPrincipal method to change the principal that is available for attaching to threads in the application domain.

Комментарии

Установка этого значения будет действовать только в том случае, если она задана перед использованием Thread.CurrentPrincipal Свойства.Setting this value will only be effective if you set it before using the Thread.CurrentPrincipal property. Например, если задать Thread.CurrentPrincipal для данного участника (например, универсальный субъект), а затем использовать SetPrincipalPolicy метод для установки значения PrincipalPolicy WindowsPrincipal , текущий участник останется универсальным.For example, if you set Thread.CurrentPrincipal to a given principal (for example, a generic principal) and then use the SetPrincipalPolicy method to set the PrincipalPolicy to WindowsPrincipal, the current principal will remain the generic principal.
