Remarques

Les identificateurs d’objet de chiffrement se composent d’une paire valeur/nom. Si une propriété d’une paire est définie sur une valeur connue, l’autre propriété est automatiquement mise à jour vers une valeur correspondante. Par exemple, si la Value propriété est définie sur « 1.3.6.1.5.5.7.3.4 », la FriendlyName propriété, qui est localisée, est définie automatiquement sur « messagerie sécurisée ».

Constructeurs

Oid()

Initialise une nouvelle instance de la classe Oid.

Oid(Oid)

Initialise une nouvelle instance de la classe Oid à l'aide de l'objet Oid spécifié.

Oid(String)

Initialise une nouvelle instance de la classe Oid à l'aide d'une valeur de chaîne d'un objet Oid.

Oid(String, String)

Initialise une nouvelle instance de la classe Oid avec la valeur et le nom convivial spécifiés.

Propriétés

FriendlyName

Obtient ou définit le nom convivial de l'identificateur.

Value

Obtient ou définit le nombre séparé par des points de l'identificateur.

Méthodes

Equals(Object)

Détermine si l'objet spécifié est égal à l'objet actuel.

(Hérité de Object)
FromFriendlyName(String, OidGroup)

Crée un objet Oid à partir d'un nom OID convivial en recherchant le groupe spécifié.

FromOidValue(String, OidGroup)

Crée un objet Oid à l'aide du groupe et de la valeur OID spécifiés.

GetHashCode()

Fait office de fonction de hachage par défaut.

(Hérité de Object)
GetType()

Obtient le Type de l'instance actuelle.

(Hérité de Object)
MemberwiseClone()

Crée une copie superficielle du Object actuel.

(Hérité de Object)
