Remarques

Vous pouvez utiliser PermissionSet pour effectuer des opérations sur plusieurs autorisations différentes en tant que groupe.You can use PermissionSet to perform operations on several different permissions as a group.

Constructeurs

PermissionSet(PermissionSet)

Initialise une nouvelle instance de la classe PermissionSet avec des valeurs initiales provenant du paramètre permSet.Initializes a new instance of the PermissionSet class with initial values taken from the permSet parameter.

PermissionSet(PermissionState)

Initialise une nouvelle instance de la classe PermissionSet avec le PermissionState spécifié.Initializes a new instance of the PermissionSet class with the specified PermissionState.

Propriétés

Count

Obtient le nombre d’objets d’autorisation contenus dans le jeu d’autorisations.Gets the number of permission objects contained in the permission set.

IsReadOnly

Obtient une valeur indiquant si la collection est en lecture seule.Gets a value indicating whether the collection is read-only.

IsSynchronized

Obtient une valeur indiquant si la collection est garantie thread-safe.Gets a value indicating whether the collection is guaranteed to be thread safe.

SyncRoot

Obtient l’objet racine de la collection actuelle.Gets the root object of the current collection.

Méthodes

AddPermission(IPermission)

Ajoute une autorisation spécifiée à l’élément PermissionSet.Adds a specified permission to the PermissionSet.

AddPermissionImpl(IPermission)

Ajoute une autorisation spécifiée à l’élément PermissionSet.Adds a specified permission to the PermissionSet.

Assert()

Déclare que le code appelant peut accéder à la ressource protégée par une demande d’autorisation via le code qui appelle cette méthode, même si les appelants situés plus haut dans la pile n’ont pas reçu l’autorisation d’accéder à la ressource.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’utilisation de Assert() permet de créer des failles de sécurité.Using Assert() can create security vulnerabilities.

ContainsNonCodeAccessPermissions()

Obtient une valeur indiquant si PermissionSet contient des autorisations qui ne sont pas dérivées de CodeAccessPermission.Gets a value indicating whether the PermissionSet contains permissions that are not derived from CodeAccessPermission.

ConvertPermissionSet(String, Byte[], String)

Convertit un objet PermissionSet encodé d’un format d’encodage XML vers un autre.Converts an encoded PermissionSet from one XML encoding format to another XML encoding format.

Copy()

Crée une copie de l'objet PermissionSet.Creates a copy of the PermissionSet.

CopyTo(Array, Int32)

Copie les objets d’autorisation du jeu à l’emplacement indiqué dans un Array.Copies the permission objects of the set to the indicated location in an Array.

Demand()

Force une SecurityException au moment de l’exécution si les premiers appelants de la pile des appels n’ont pas reçu les autorisations spécifiées par l’instance actuelle.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()

Entraîne l’échec de tout Demand() qui passe par le code appelant pour une autorisation qui possède une intersection avec une autorisation d’un type contenu dans le PermissionSet actuel.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)

Détermine si l’objet PermissionSet ou NamedPermissionSet spécifié est égal au PermissionSet actuel.Determines whether the specified PermissionSet or NamedPermissionSet object is equal to the current PermissionSet.

FromXml(SecurityElement)

Reconstruit un objet de sécurité avec un état spécifié à partir d’un encodage XML.Reconstructs a security object with a specified state from an XML encoding.

GetEnumerator()

Retourne un énumérateur pour les autorisations de l’ensemble.Returns an enumerator for the permissions of the set.

GetEnumeratorImpl()

Retourne un énumérateur pour les autorisations de l’ensemble.Returns an enumerator for the permissions of the set.

GetHashCode()

Obtient un code de hachage pour l’objet PermissionSet qui peut être utilisé dans des structures de données et des algorithmes de hachage, comme une table de hachage.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)

Obtient un objet d’autorisation du type spécifié, s’il existe dans le jeu.Gets a permission object of the specified type, if it exists in the set.

GetPermissionImpl(Type)

Obtient un objet d’autorisation du type spécifié, s’il existe dans le jeu.Gets a permission object of the specified type, if it exists in the set.

GetType()

Obtient le Type de l'instance actuelle.Gets the Type of the current instance.

(Hérité de Object)
Intersect(PermissionSet)

Crée et retourne un un jeu d’autorisations qui est l’intersection entre le PermissionSet actuel et le PermissionSet spécifié.Creates and returns a permission set that is the intersection of the current PermissionSet and the specified PermissionSet.
