Commenti

Dopo aver creato la ClaimSet classe, non può essere modificata.

L'analisi del contenuto di un ClaimSet per particolari tipi di attestazioni è un'attività comune quando si utilizza l'autorizzazione basata su attestazioni. Per esaminare un ClaimSet per la presenza di attestazioni specifiche, usare il metodo FindClaims. Il metodo offre prestazioni migliori rispetto all'iterazione ClaimSetdiretta su .
