SecurityPermissionFlag Enumerazione
Definizione
Importante
Alcune informazioni sono relative alla release non definitiva del prodotto, che potrebbe subire modifiche significative prima della release definitiva. Microsoft non riconosce alcuna garanzia, espressa o implicita, in merito alle informazioni qui fornite.
Attenzione
Code Access Security is not supported or honored by the runtime.
Attenzione
CAS support is not available with Silverlight applications.
Specifica i flag di accesso per l'oggetto autorizzazione di sicurezza.
Questa enumerazione supporta una combinazione bit per bit dei rispettivi valori dei membri.

Campi
| AllFlags | 16383 | Stato senza restrizioni dell'autorizzazione. |
| Assertion | 1 | Capacità di asserire che tutti i chiamanti del codice dispongono dell'autorizzazione necessaria per l'operazione. |
| BindingRedirects | 8192 | Autorizzazione ad eseguire un reindirizzamento esplicito dell'associazione nel file di configurazione dell'applicazione. Include il reindirizzamento di assembly di .NET che sono stati unificati, oltre a quello di altri assembly trovati al di fuori di .NET. |
| ControlAppDomain | 1024 | Capacità di creare e manipolare un oggetto AppDomain. |
| ControlDomainPolicy | 256 | Capacità di specificare i criteri del dominio. |
| ControlEvidence | 32 | Capacità di fornire l'evidenza, inclusa la possibilità di alterare le prove di Common Language Runtime. Si tratta di un'autorizzazione efficace che deve essere concessa esclusivamente a codice altamente attendibile. |
| ControlPolicy | 64 | Capacità di visualizzare e modificare i criteri. Si tratta di un'autorizzazione efficace che deve essere concessa esclusivamente a codice altamente attendibile. |
| ControlPrincipal | 512 | Capacità di manipolare gli oggetti Principal. |
| ControlThread | 16 | Capacità di eseguire alcune operazioni avanzate sui thread. |
| Execution | 8 | Autorizzazione a eseguire il codice. Senza questa autorizzazione, il codice gestito non verrà eseguito. Questo flag non ha alcun effetto se usato in modo dinamico con i modificatori di stack, ad esempio Deny(), Assert() e PermitOnly(). |
| Infrastructure | 4096 | Autorizzazione a inserire il codice nell’infrastruttura Common Language Runtime, ad esempio aggiungendo sink di contesto remoto, di invio e dinamici. |
| NoFlags | 0 | Nessun accesso di sicurezza. |
| RemotingConfiguration | 2048 | Autorizzazione alla configurazione di canali e tipi remoti. |
| SerializationFormatter | 128 | Capacità di fornire servizi di serializzazione. Utilizzato dai formattatori di serializzazione. |
| SkipVerification | 4 | Capacità di ignorare la verifica del codice in questo assembly. Se viene concessa questa autorizzazione, sarà possibile eseguire un codice non verificabile. Si tratta di un'autorizzazione efficace che deve essere concessa esclusivamente a codice altamente attendibile. Questo flag non ha alcun effetto se usato in modo dinamico con i modificatori di stack, ad esempio Deny(), Assert() e PermitOnly(). |
| UnmanagedCode | 2 | Capacità di richiamare codice non gestito. Poiché il codice non gestito consente potenzialmente di ignorare altre autorizzazioni, si tratta di un'autorizzazione pericolosa che deve essere concessa solo a codice altamente attendibile. Viene usata per applicazioni come la chiamata di codice nativo tramite PInvoke o tramite l'interoperabilità COM. |
Esempio

Attenzione
La sicurezza di accesso al codice è stata deprecata in tutte le versioni di .NET Framework e .NET. Le versioni recenti di .NET non rispettano le annotazioni CAS e generano errori se vengono usate API correlate a CAS. Gli sviluppatori devono cercare mezzi alternativi per eseguire attività di sicurezza.
Questa enumerazione viene usata da SecurityPermission.
Attenzione
Molti di questi flag sono potenti e devono essere concessi solo al codice altamente attendibile.
