Remarques

La structure X.509 provient de l’organisation internationale de normalisation (ISO) groupes de travail.The X.509 structure originated in the International Organization for Standardization (ISO) working groups. Cette structure peut être utilisée pour représenter les différents types d’informations, y compris les attributs d’identité, le droit et titulaire (autorisations, âge, sexe, emplacement, affiliation et ainsi de suite).This structure can be used to represent various types of information including identity, entitlement, and holder attributes (permissions, age, sex, location, affiliation, and so forth). Bien que les spécifications ISO plus d’informations sur la structure elle-même, la X509Certificate2 classe est conçue pour modéliser des scénarios d’utilisation définis dans les spécifications émises par l’Internet Engineering Task Force (IETF) Public Key Infrastructure X.509 (PKIX ) groupe de travail.Although the ISO specifications are most informative on the structure itself, the X509Certificate2 class is designed to model the usage scenarios defined in specifications issued by the Internet Engineering Task Force (IETF) Public Key Infrastructure, X.509 (PKIX) working group. Précieuses de ces spécifications est la norme RFC 3280, «certificat et profil de liste de révocation de la révocation de certificat. »The most informative of these specifications is RFC 3280, "Certificate and Certificate Revocation List (CRL) Profile."

Lorsque vous avez fini d’utiliser le type, vous devez supprimer il directement ou indirectement.When you have finished using the type, you should dispose of it either directly or indirectly. Pour supprimer le type directement, appelez sa Dispose méthode dans un try / catch bloc.To dispose of the type directly, call its Dispose method in a try/catch block. Pour supprimer indirectement, utiliser une construction de langage tel que using (en c#) ou Using (en Visual Basic).To dispose of it indirectly, use a language construct such as using (in C#) or Using (in Visual Basic). Pour plus d’informations, consultez la section « À l’aide un objet qui implémente IDisposable » dans le IDisposable rubrique de l’interface.For more information, see the "Using an Object that Implements IDisposable" section in the IDisposable interface topic.

Pour les applications qui ciblent le .NET Framework 4.5.2.NET Framework 4.5.2 et versions antérieures, le X509Certificate2 classe n’implémente pas le IDisposable interface et par conséquent n’a pas un Dispose (méthode).For apps that target the .NET Framework 4.5.2.NET Framework 4.5.2 and earlier versions, the X509Certificate2 class does not implement the IDisposable interface and therefore does not have a Dispose method.
