Exemples

L’exemple de code suivant montre comment appliquer l’assembly AssemblyFlagsAttribute à un assembly et comment lire les indicateurs au moment de l’exécution. L’exemple crée également une instance de l’attribut et utilise la AssemblyFlags propriété pour afficher les indicateurs. Pour obtenir un exemple d’application de l’assembly AssemblyFlagsAttribute dynamique, consultez la AssemblyName.Flags propriété.

Remarques

L’énumération AssemblyNameFlags décrit les caractéristiques d’assembly qui peuvent être définies à l’aide de cet attribut.

Pour accéder aux indicateurs spécifiés pour un assembly, utilisez la Assembly.GetName() propriété pour obtenir un AssemblyName objet, puis utilisez la AssemblyName.Flags propriété pour obtenir une AssemblyNameFlags valeur.

Pour spécifier AssemblyNameFlags des indicateurs pour un assembly dynamique, définissez la AssemblyName.Flags propriété de l’objet AssemblyName que vous passez à la AppDomain.DefineDynamicAssembly méthode.
