Definición

Especifica la forma en que los objetos principales y de identidad deben asociarse a un subproceso si éste intenta enlazarse a un principal mientas se ejecuta en este dominio de aplicación.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.

Public Sub SetPrincipalPolicy (policy As PrincipalPolicy)

Parámetros

policy
PrincipalPolicy PrincipalPolicy PrincipalPolicy PrincipalPolicy

Uno de los valores de PrincipalPolicy que especifica el tipo del objeto principal que se va a asociar a los subprocesos.One of the PrincipalPolicy values that specifies the type of the principal object to attach to threads.

Excepciones

La operación se intenta en un dominio de aplicación descargado.The operation is attempted on an unloaded application domain.

Ejemplos

El ejemplo siguiente muestra el efecto en los subprocesos del uso de la SetPrincipalPolicy método para cambiar la directiva de entidad del dominio de aplicación.The following example shows the effect on threads of using the SetPrincipalPolicy method to change the principal policy of the application domain. También se muestra el efecto de usar el SetThreadPrincipal método para cambiar la entidad de seguridad que está disponible para asociar a los subprocesos en el dominio de aplicación.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.

Comentarios

Al establecer este valor sólo serán efectivo si se establece antes de usar el Thread.CurrentPrincipal propiedad.Setting this value will only be effective if you set it before using the Thread.CurrentPrincipal property. Por ejemplo, si establece Thread.CurrentPrincipal a una entidad determinada (por ejemplo, una entidad de seguridad genérico) y, después, use el SetPrincipalPolicy método para establecer el PrincipalPolicy a WindowsPrincipal, la entidad de seguridad actual seguirá siendo la entidad de seguridad genérico.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.
