Public Sub SetPrincipalPolicy (policy As PrincipalPolicy)

Parametri

policy: PrincipalPolicy

Uno dei valori dell'enumerazione PrincipalPolicy che specifica il tipo dell'oggetto Principal da associare ai thread.

Implementazioni

SetPrincipalPolicy(PrincipalPolicy)

Eccezioni

AppDomainUnloadedException

L'operazione viene tentata in un dominio dell'applicazione non caricato.

Esempio

Nell'esempio seguente viene illustrato l'effetto sui thread dell'uso del SetPrincipalPolicy metodo per modificare i criteri principale del dominio applicazione. Mostra anche l'effetto dell'uso del SetThreadPrincipal metodo per modificare l'entità disponibile per il collegamento ai thread nel dominio applicazione.

Commenti

L'impostazione di questo valore sarà effettiva solo se la si imposta prima di usare la Thread.CurrentPrincipal proprietà . Ad esempio, se si imposta su Thread.CurrentPrincipal un'entità specifica (ad esempio, un'entità generica) e quindi si usa il SetPrincipalPolicy metodo per impostare su PrincipalPolicy WindowsPrincipal, l'entità corrente rimarrà l'entità generica.
