Commenti

È possibile utilizzare PermissionSet per eseguire operazioni su più autorizzazioni diverse come gruppo.You can use PermissionSet to perform operations on several different permissions as a group.

Costruttori

PermissionSet(PermissionSet)

Inizializza una nuova istanza della classe PermissionSet usando come valori iniziali quelli del parametro permSet.Initializes a new instance of the PermissionSet class with initial values taken from the permSet parameter.

PermissionSet(PermissionState)

Inizializza una nuova istanza della classe PermissionSet con l'oggetto PermissionState specificato.Initializes a new instance of the PermissionSet class with the specified PermissionState.

Proprietà

Count

Ottiene il numero di oggetti autorizzazioni contenuti nel set di autorizzazioni.Gets the number of permission objects contained in the permission set.

IsReadOnly

Ottiene un valore che indica se la raccolta è di sola lettura.Gets a value indicating whether the collection is read-only.

IsSynchronized

Ottiene un valore che indica se la raccolta è sicuramente thread-safe.Gets a value indicating whether the collection is guaranteed to be thread safe.

SyncRoot

Ottiene l'oggetto radice della raccolta corrente.Gets the root object of the current collection.

Metodi

AddPermission(IPermission)

Aggiunge un'autorizzazione specificata a PermissionSet.Adds a specified permission to the PermissionSet.

AddPermissionImpl(IPermission)

Aggiunge un'autorizzazione specificata a PermissionSet.Adds a specified permission to the PermissionSet.

Assert()

Dichiara che il codice chiamante può accedere alla risorsa protetta da una richiesta di autorizzazione tramite il codice che chiama il metodo, anche se ai chiamanti più in alto nello stack non è stata concessa l'autorizzazione per accedere alla risorsa.Declares that the calling code can access the resource protected by a permission demand through the code that calls this method, even if callers higher in the stack have not been granted permission to access the resource. L'uso di Assert() può creare problemi di sicurezza.Using Assert() can create security vulnerabilities.

ContainsNonCodeAccessPermissions()

Ottiene un valore che indica se l'oggetto PermissionSet contiene autorizzazioni che non sono derivate da CodeAccessPermission.Gets a value indicating whether the PermissionSet contains permissions that are not derived from CodeAccessPermission.

ConvertPermissionSet(String, Byte[], String)

Converte un oggetto PermissionSet codificato da un formato di codifica XML in un altro formato di codifica XML.Converts an encoded PermissionSet from one XML encoding format to another XML encoding format.

Copy()

Crea una copia di PermissionSet.Creates a copy of the PermissionSet.

CopyTo(Array, Int32)

Copia gli oggetti di autorizzazione del set nel percorso indicato in un oggetto Array.Copies the permission objects of the set to the indicated location in an Array.

Demand()

Forza un oggetto SecurityException in fase di esecuzione se a tutti i chiamanti nella parte superiore dello stack di chiamate non sono state concesse le autorizzazioni specificate dall'istanza corrente.Forces a SecurityException at run time if all callers higher in the call stack have not been granted the permissions specified by the current instance.

Deny()

Causa la non riuscita di tutti i metodi Demand() che attraversano il codice chiamante per un'autorizzazione che presenta un'intersezione con un'autorizzazione di un tipo contenuto nell'oggetto PermissionSet corrente.Causes any Demand() that passes through the calling code for a permission that has an intersection with a permission of a type contained in the current PermissionSet to fail.

Equals(Object)

Determina se l'oggetto PermissionSet o NamedPermissionSet specificato è uguale all'oggetto PermissionSet corrente.Determines whether the specified PermissionSet or NamedPermissionSet object is equal to the current PermissionSet.

FromXml(SecurityElement)

Ricostruisce un oggetto di sicurezza con uno stato specificato da una codifica XML.Reconstructs a security object with a specified state from an XML encoding.

GetEnumerator()

Restituisce un enumeratore per le autorizzazioni del set.Returns an enumerator for the permissions of the set.

GetEnumeratorImpl()

Restituisce un enumeratore per le autorizzazioni del set.Returns an enumerator for the permissions of the set.

GetHashCode()

Ottiene un codice hash per l'oggetto PermissionSet adatto per l'uso in algoritmi di hash e in strutture di dati, come una tabella hash.Gets a hash code for the PermissionSet object that is suitable for use in hashing algorithms and data structures such as a hash table.

GetPermission(Type)

Ottiene un oggetto di autorizzazione del tipo specificato, se è presente nel set.Gets a permission object of the specified type, if it exists in the set.

GetPermissionImpl(Type)

Ottiene un oggetto di autorizzazione del tipo specificato, se è presente nel set.Gets a permission object of the specified type, if it exists in the set.

GetType()

Ottiene l'oggetto Type dell'istanza corrente.Gets the Type of the current instance.

(Ereditato da Object)
Intersect(PermissionSet)

Crea e restituisce un set di autorizzazioni che rappresenta l'intersezione tra l'oggetto PermissionSet corrente e quello PermissionSet specificato.Creates and returns a permission set that is the intersection of the current PermissionSet and the specified PermissionSet.
