Costruttori

GenericPrincipal(IIdentity, String[])

Inizializza una nuova istanza della classe GenericPrincipal da un'identità utente e una matrice di nomi di ruolo a cui appartiene l'utente rappresentato dall'identità.

Proprietà

Claims	Ottiene una raccolta che contiene tutte le attestazioni da tutte le identità di attestazioni associate all'entità delle attestazioni. (Ereditato da ClaimsPrincipal)
CustomSerializationData	Contiene i dati aggiuntivi forniti da un tipo derivato. Generalmente impostato durante la chiamata a WriteTo(BinaryWriter, Byte[]). (Ereditato da ClaimsPrincipal)
Identities	Ottiene una raccolta che contiene tutte le identità delle attestazioni associate a questa entità attestazioni. (Ereditato da ClaimsPrincipal)
Identity	Ottiene l'oggetto GenericIdentity dell'utente rappresentato dall'oggetto GenericPrincipal corrente.

Metodi

AddIdentities(IEnumerable<ClaimsIdentity>)	Aggiunge le identità delle attestazioni specificate a questa entità delle attestazioni. (Ereditato da ClaimsPrincipal)

FindFirst(Predicate<Claim>)	Recupera la prima attestazione che corrisponde al predicato specificato. (Ereditato da ClaimsPrincipal)
FindFirst(String)	Recupera la prima attestazione con il tipo di attestazione specificato. (Ereditato da ClaimsPrincipal)
GetHashCode()	Funge da funzione hash predefinita. (Ereditato da Object)
GetObjectData(SerializationInfo, StreamingContext)	Popola l'oggetto SerializationInfo con i dati necessari per serializzare l'oggetto ClaimsPrincipal corrente. (Ereditato da ClaimsPrincipal)
GetType()	Ottiene l'oggetto Type dell'istanza corrente. (Ereditato da Object)
HasClaim(Predicate<Claim>)	Determina se una qualsiasi delle identità di attestazione associate all'entità delle attestazioni contiene un'attestazione a cui corrisponde il predicato specificato. (Ereditato da ClaimsPrincipal)
HasClaim(String, String)	Determina se una qualsiasi delle identità di attestazione associate all'entità delle attestazioni contiene un'attestazione con il tipo e il valore specificati. (Ereditato da ClaimsPrincipal)
IsInRole(String)	Determina se l'oggetto GenericPrincipal corrente appartiene al ruolo specificato.
MemberwiseClone()	Crea una copia superficiale dell'oggetto Object corrente. (Ereditato da Object)
