- Attributs
Champs
| AllFlags | 16383 | État sans restriction de l'autorisation. |
| Assertion | 1 | Possibilité de déclarer que tous les appelants de ce code ont l'autorisation requise pour l'opération. |
| BindingRedirects | 8192 | Autorisation d'effectuer une redirection de liaison explicite dans le fichier de configuration de l'application. Elle inclut la redirection des assemblys .NET qui ont été unifiés ainsi que d'autres assemblys ne faisant pas partie de .NET. |
| ControlAppDomain | 1024 | Possibilité de créer et manipuler un AppDomain. |
| ControlDomainPolicy | 256 | Possibilité de spécifier une stratégie de domaine. |
| ControlEvidence | 32 | Possibilité de fournir une preuve, notamment de modifier la preuve fournie par le Common Language Runtime. Il s’agit d’une autorisation puissante qui ne peut être octroyée qu’à un code hautement fiable. |
| ControlPolicy | 64 | Possibilité d'afficher et de modifier la stratégie. Il s’agit d’une autorisation puissante qui ne peut être octroyée qu’à un code hautement fiable. |
| ControlPrincipal | 512 | Possibilité de manipuler l'objet Principal |
| ControlThread | 16 | Possibilité d'utiliser certaines opérations avancées sur les threads. |
| Execution | 8 | Autorisation d'exécution du code. Sans cette autorisation, le code managé ne peut pas s'exécuter. Cet indicateur n’a aucun effet lorsqu’il est utilisé dynamiquement avec les modificateurs de pile comme Deny(), Assert(), et PermitOnly(). |
| Infrastructure | 4096 | Autorisation d'assembler du code dans l'infrastructure du Common Language Runtime, par exemple en ajoutant Remoting Context Sinks, Envoy Sinks et Dynamic Sinks. |
| NoFlags | 0 | Aucun accès de sécurité. |
| RemotingConfiguration | 2048 | Autorisation de configurer des canaux et des types de communication à distance. |
| SerializationFormatter | 128 | Possibilité de fournir des services de sérialisation. Utilisée par les formateurs de sérialisation. |
| SkipVerification | 4 | Possibilité d'omettre la vérification du code dans cet assembly. Le code qui n'est pas vérifiable peut être exécuté si cette autorisation est accordée. Il s’agit d’une autorisation puissante qui ne peut être octroyée qu’à un code hautement fiable. Cet indicateur n’a aucun effet lorsqu’il est utilisé dynamiquement avec les modificateurs de pile comme Deny(), Assert(), et PermitOnly(). |
| UnmanagedCode | 2 | Possibilité d'appeler du code non managé. Étant donné que le code non managé permet potentiellement d’ignorer d’autres autorisations, il s’agit d’une autorisation dangereuse qui ne doit être octroyée qu’au code hautement fiable. Il est utilisé pour les applications telles que l’appel de code natif à l’aide de PInvoke ou à l’aide de COM interop. |

Remarques
Attention
La sécurité de l’accès au code (CAS) a été déconseillée dans toutes les versions de .NET Framework et .NET. Les versions récentes de .NET ne respectent pas les annotations CAS et produisent des erreurs si les API associées au cas sont utilisées. Les développeurs doivent rechercher d’autres moyens d’accomplir des tâches de sécurité.
Cette énumération est utilisée par SecurityPermission.
Attention
Bon nombre de ces indicateurs sont puissants et ne doivent être accordés qu’au code hautement approuvé.
