Remarques

Utilisez cette surcharge de méthode pour spécifier des attributs qui ne fonctionnent pas correctement, sauf s’ils sont appliqués lors de la création d’un assembly dynamique. Par exemple, les attributs de sécurité tels que SecurityTransparentAttribute et SecurityCriticalAttribute ne fonctionnent pas correctement s’ils sont ajoutés après la création d’un assembly dynamique.

Les demandes d’autorisation spécifiées pour les requiredPermissionsparamètres , optionalPermissionset refusedPermissions sont utilisées uniquement si le evidence paramètre est également fourni ou si l’assembly dynamique est enregistré et rechargé en mémoire.

Seuls les appelants entièrement approuvés peuvent fournir des preuves lors de la définition d’un élément dynamique Assembly. Le runtime mappe le Evidence via la stratégie de sécurité pour déterminer les autorisations accordées. Les appelants partiellement approuvés doivent fournir null pour le evidence paramètre. Si evidence a la valeur null, le runtime copie les jeux d’autorisations (c’est-à-dire les jeux d’octroi et de refus actuels) de l’assembly de l’appelant vers l’assembly dynamique en cours de définition, et marque la stratégie comme résolue.

Si l’assembly dynamique est enregistré sur le disque, les charges suivantes obtiennent des subventions en fonction des stratégies associées à l’emplacement où l’assembly dynamique a été enregistré.

Si isSynchronized a la valeur true, les méthodes suivantes du résultat AssemblyBuilder seront synchronisées : DefineDynamicModule, DefineResource, AddResourceFile, GetDynamicModule, , SetEntryPointet Save. Si deux de ces méthodes sont appelées sur des threads différents, l’une est bloquée jusqu’à ce que l’autre soit terminée.

Cette surcharge de méthode est introduite dans .NET Framework 3.5.

Remarques

Les demandes d’autorisation spécifiées pour requiredPermissions, optionalPermissionset refusedPermissions ne sont utilisées que si l’assembly dynamique a été enregistré et rechargé en mémoire. Pour spécifier les demandes d’autorisation pour un assembly temporaire qui n’est jamais enregistré sur le disque, utilisez une surcharge de la DefineDynamicAssembly méthode qui spécifie les preuves ainsi que les autorisations demandées et fournissez un Evidence objet.

Cette méthode doit uniquement être utilisée pour définir un assembly dynamique dans le domaine d’application actuel. Pour plus d’informations, consultez la surcharge de Load(AssemblyName) méthode.

Remarques

Les demandes d’autorisation spécifiées pour requiredPermissions, optionalPermissionset refusedPermissions ne sont utilisées que si evidence est également fourni ou si l’assembly dynamique est enregistré et rechargé en mémoire.

Seuls les appelants entièrement approuvés peuvent fournir leur evidence lors de la définition d’un dynamique Assembly. Le runtime mappe le Evidence via la stratégie de sécurité pour déterminer les autorisations accordées. Les appelants partiellement approuvés doivent fournir une valeur null evidence. Si evidence a la valeur null, le runtime copie les jeux d’autorisations, c’est-à-dire les jeux d’octroi et de refus actuels, de l’appelant Assembly à la dynamique Assembly en cours de définition et marque la stratégie comme résolue.

Si la dynamique Assembly est enregistrée sur le disque, les charges suivantes recevront des subventions en fonction des stratégies associées à l’emplacement où le Assembly a été enregistré.

Cette méthode doit uniquement être utilisée pour définir un assembly dynamique dans le domaine d’application actuel. Pour plus d’informations, consultez la surcharge de Load(AssemblyName) méthode.

Remarques

Utilisez cette surcharge de méthode pour spécifier des attributs qui ne fonctionnent pas correctement, sauf s’ils sont appliqués lors de la création d’un assembly dynamique. Par exemple, les attributs de sécurité tels que SecurityTransparentAttribute et SecurityCriticalAttribute ne fonctionnent pas correctement s’ils sont ajoutés après la création d’un assembly dynamique.

Si isSynchronized a la valeur true, les méthodes suivantes du résultat AssemblyBuilder seront synchronisées : DefineDynamicModule, DefineResource, AddResourceFile, GetDynamicModule, , SetEntryPointet Save. Si deux de ces méthodes sont appelées sur des threads différents, l’une est bloquée jusqu’à ce que l’autre soit terminée.

Remarques

Seuls les appelants entièrement approuvés peuvent fournir leur evidence lors de la définition d’un .Assembly Le runtime mappe le Evidence via la stratégie de sécurité pour déterminer les autorisations accordées. Les appelants partiellement approuvés doivent fournir une valeur null evidence. Si evidence a la valeur null, le runtime copie les jeux d’autorisations, c’est-à-dire les jeux d’octroi et de refus actuels, de l’appelant Assembly à la dynamique Assembly en cours de définition et marque la stratégie comme résolue.

Si la dynamique Assembly est enregistrée sur le disque, les charges suivantes obtiennent des allocations basées sur les stratégies associées à l’emplacement où Assembly a été enregistré.

L’exemple suivant illustre la DefineDynamicAssembly méthode et l’événement AssemblyResolve .

Tout d’abord, l’exemple de code tente de créer un instance de MyDynamicType en appelant la CreateInstance méthode avec un nom d’assembly non valide et intercepte l’exception résultante.

L’exemple de code ajoute ensuite un gestionnaire d’événements pour l’événementAssemblyResolve, puis tente à nouveau de créer un instance deMyDynamicType . Pendant l’appel à CreateInstance, l’événement AssemblyResolve est déclenché pour l’assembly non valide. Le gestionnaire d’événements crée un assembly dynamique qui contient un type nommé MyDynamicType, donne au type un constructeur sans paramètre et retourne le nouvel assembly dynamique. L’appel à CreateInstance se termine alors correctement et le constructeur pour MyDynamicType affiche un message sur la console.

Remarques

Seuls les appelants entièrement approuvés peuvent fournir leur evidence lors de la définition d’un dynamique Assembly. Le runtime mappe le Evidence via la stratégie de sécurité pour déterminer les autorisations accordées. Les appelants partiellement approuvés doivent fournir une valeur null evidence. Si evidence a la valeur null, le runtime copie les jeux d’autorisations, c’est-à-dire les jeux d’octroi et de refus actuels, de l’appelant Assembly à la dynamique Assembly en cours de définition et marque la stratégie comme résolue.

Si la dynamique Assembly est enregistrée sur le disque, les charges suivantes recevront des subventions en fonction des stratégies associées à l’emplacement où le Assembly a été enregistré.

Cette méthode doit uniquement être utilisée pour définir un assembly dynamique dans le domaine d’application actuel. Pour plus d’informations, consultez la surcharge de Load(AssemblyName) méthode.

Exemples

L’exemple de code suivant montre comment créer un assembly dynamique qui a le SecurityTransparentAttribute. L’attribut doit être spécifié en tant qu’élément d’un tableau d’objets CustomAttributeBuilder .

La première étape de la création de CustomAttributeBuilder consiste à obtenir un constructeur pour l’attribut. Le constructeur n’ayant aucun paramètre, la GetConstructor méthode est appelée avec un tableau vide d’objets Type pour représenter les types des paramètres. La deuxième étape consiste à passer l’objet résultant ConstructorInfo au constructeur de la CustomAttributeBuilder classe, ainsi qu’un tableau vide de type Object pour représenter les arguments.

Le résultat CustomAttributeBuilder est ensuite passé à la DefineDynamicAssembly méthode en tant que seul élément d’un tableau.

L’exemple de code définit un module et un type dans le nouvel assembly dynamique, puis affiche les attributs de l’assembly.

Remarques

Utilisez cette surcharge de méthode pour spécifier des attributs qui ne fonctionnent pas correctement, sauf s’ils sont appliqués lors de la création d’un assembly dynamique. Par exemple, les attributs de sécurité tels que SecurityTransparentAttribute et SecurityCriticalAttribute ne fonctionnent pas correctement s’ils sont ajoutés après la création d’un assembly dynamique.
