Exemples

L'exemple suivant montre l'utilisation de GacIdentityPermissionAttribute.

// To run this sample you must create a strong-name key named snkey.snk 
// using the Strong Name tool (sn.exe).  Both the library assembly and the 
// application assembly that calls it must be signed with that key.  
// To run successfully, the application assembly must be in the global 
// assembly cache.
// This console application can be created using the following code.

//#using <mscorlib.dll>
//#using <ClassLibrary1.dll>
//using namespace System;
//using namespace System::Security;
//using namespace System::Reflection;
//using namespace ClassLibrary1;

Remarques

Cette classe permet de s’assurer que les appelants sont inscrits dans le Global Assembly Cache (GAC).

L’étendue de la déclaration autorisée dépend de la SecurityAction valeur utilisée.

Les informations de sécurité déclarées par un attribut de sécurité sont stockées dans les métadonnées de la cible d’attribut et sont accessibles par le système au moment de l’exécution. Les attributs de sécurité sont utilisés uniquement pour la sécurité déclarative. Pour une sécurité impérative, utilisez la classe d’autorisation correspondante, GacIdentityPermission.

Pour plus d’informations sur l’utilisation des attributs, consultez Attributs.
