Exemples

Cette section fournit deux exemples de code. La première montre comment spécifier de manière déclarative des valeurs pour plusieurs propriétés de la TrustSection classe. La deuxième montre comment utiliser le TrustSection type.

L’exemple de fichier de configuration suivant montre comment spécifier de manière déclarative des valeurs pour plusieurs propriétés de la TrustSection classe.

<system.web>
  <trust level="Full" originUrl=""/>
</system.web>

L’exemple de code suivant montre comment utiliser le TrustSection type.

Remarques

La TrustSection classe vous permet d’accéder par programmation et de modifier la section du fichier <trust> de configuration. La <trust> section configure le jeu d’autorisations de sécurité d’accès au code utilisé pour exécuter une application particulière. Cette section peut être déclarée au niveau de l’ordinateur, du site et de l’application.
