Hiermee wordt de AppDomainInitializer gemachtigde opgehaald of ingesteld, die een callback-methode vertegenwoordigt die wordt aangeroepen wanneer het toepassingsdomein wordt geïnitialiseerd.

Een gemachtigde die een callback-methode vertegenwoordigt die wordt aangeroepen wanneer het toepassingsdomein wordt geïnitialiseerd.
Voorbeelden
In het volgende voorbeeld wordt een onderliggend toepassingsdomein gemaakt met ChildDomainbehulp van een AppDomainSetup object en bewijs van het standaardtoepassingsdomein. De AppDomainInitializer eigenschap is ingesteld op de callback-methode AppDomainInit, die wordt aangeroepen wanneer het onderliggende domein wordt geïnitialiseerd. De argumenten voor de callback-methode worden geplaatst in een matrix met tekenreeksen, die is toegewezen aan de AppDomainInitializerArguments eigenschap. Wanneer het onderliggende domein wordt gemaakt, worden de tekenreeksen gewoon afgedrukt met de callback-methode.

Opmerkingen
Als u informatie wilt doorgeven aan de callback-methode, wijst u een matrix met tekenreeksen toe aan de AppDomainInitializerArguments eigenschap. De matrix wordt doorgegeven aan de callback-methode telkens wanneer een AppDomain wordt geïnitialiseerd.
De callback-methode wordt uitgevoerd in de context van het zojuist gemaakte toepassingsdomein.
