AppDomainInitializer

Délégué qui représente une méthode de rappel appelée lorsque le domaine d'application est initialisé.

Exemples

L’exemple suivant crée un domaine d’application enfant nommé ChildDomain, à l’aide d’un objet et d’une AppDomainSetup preuve du domaine d’application par défaut. La AppDomainInitializer propriété est définie sur la méthode AppDomainInitde rappel , qui est appelée lorsque le domaine enfant est initialisé. Les arguments de la méthode de rappel sont placés dans un tableau de chaînes, qui est affecté à la AppDomainInitializerArguments propriété . Lorsque le domaine enfant est créé, la méthode de rappel imprime simplement les chaînes.

Remarques

Pour transmettre des informations à la méthode de rappel, affectez un tableau de chaînes à la AppDomainInitializerArguments propriété . Le tableau est passé à la méthode de rappel chaque fois qu’un AppDomain est initialisé.

La méthode de rappel est exécutée dans le contexte du domaine d’application nouvellement créé.
