AppDomainSetup.AppDomainInitializer Свойство

Определение

Возвращает или задает делегат AppDomainInitializer, представляющий метод обратного вызова, вызываемый при инициализации домена приложения.

public:
 property AppDomainInitializer ^ AppDomainInitializer { AppDomainInitializer ^ get(); void set(AppDomainInitializer ^ value); };
public AppDomainInitializer AppDomainInitializer { get; set; }
member this.AppDomainInitializer : AppDomainInitializer with get, set
Public Property AppDomainInitializer As AppDomainInitializer

Значение свойства

AppDomainInitializer

Делегат, представляющий метод обратного вызова, вызываемый при инициализации домена приложения.

Примеры

В следующем примере создается дочерний домен приложения с именем ChildDomain , AppDomainSetup а также объект и свидетельство из домена приложения по умолчанию. AppDomainInitializerСвойству присваивается метод обратного вызова AppDomainInit , который вызывается при инициализации дочернего домена. Аргументы для метода обратного вызова помещаются в массив строк, который присваивается AppDomainInitializerArguments свойству. При создании дочернего домена метод обратного вызова просто выводит строки.

Комментарии

Чтобы передать сведения в метод обратного вызова, назначьте AppDomainInitializerArguments свойству массив строк. Массив передается в метод обратного вызова каждый раз, когда AppDomain инициализируется.

Метод обратного вызова выполняется в контексте только что созданного домена приложения.
