Obtiene o establece el delegado de AppDomainInitializer, que representa un método de devolución de llamada que se invoca cuando se inicializa el dominio de aplicación.

public:
 property AppDomainInitializer ^ AppDomainInitializer { AppDomainInitializer ^ get(); void set(AppDomainInitializer ^ value); };

public AppDomainInitializer AppDomainInitializer { get; set; }

Public Property AppDomainInitializer As AppDomainInitializer

Valor de propiedad

AppDomainInitializer

Un delegado que representa un método de devolución de llamada que se invoca cuando se inicializa el dominio de aplicación.

Ejemplos

En el ejemplo siguiente se crea un dominio de aplicación secundario denominado ChildDomain, mediante un AppDomainSetup objeto y evidencia del dominio de aplicación predeterminado. La AppDomainInitializer propiedad se establece en el método AppDomainInitde devolución de llamada , que se invoca cuando se inicializa el dominio secundario. Los argumentos del método de devolución de llamada se colocan en una matriz de cadenas, que se asigna a la AppDomainInitializerArguments propiedad . Cuando se crea el dominio secundario, el método de devolución de llamada simplemente imprime las cadenas.

Comentarios

Para pasar información al método de devolución de llamada, asigne una matriz de cadenas a la AppDomainInitializerArguments propiedad . La matriz se pasa al método de devolución de llamada cada vez que se inicializa .AppDomain

El método de devolución de llamada se ejecuta en el contexto del dominio de aplicación recién creado.
