Exemples

L’exemple suivant montre comment utiliser les deux surcharges de la ResolveMethod méthode pour résoudre les jetons de métadonnées à partir de sites d’appel dans des contextes génériques et non génériques.

L’exemple de code définit deux types génériques et G1<Tg1>G2<Tg2>, chacun d’eux ayant une méthode générique. G1<Tg1> possède également une méthode non générique qui utilise le paramètre Tg1 de type pour son paramètre. La méthode GM2<Tgm2> générique en type G2<Tg2> contient plusieurs appels de méthode :

• Cas 1 : La méthode GM1<Tgm1> générique est appelée, en utilisant les paramètres de type et GM2<Tgm2>G2<Tg2> en tant qu’arguments de type. En d’autres termes, les types de paramètres de la méthode appelée dépendent des types utilisés pour construire un type générique fermé à partir de la définition de type pour G2<Tg2>.

• Cas 2 : La méthode M1 non générique est appelée. Le paramètre de cette méthode utilise le paramètre de type du type de définition, G1<Tg1>qui est remplacé dans ce cas par le paramètre de type du type englobant, G2<Tg2>.

• Cas 3 : La méthode GM1<Tgm1> générique est appelée, spécifiant Int32 et Object pour les arguments de type du type générique et de la méthode générique, respectivement. Cet appel de méthode ne dépend pas des paramètres de type du type englobant ou de la méthode.

• Cas 4 : La méthode M1 non générique de la Example classe est appelée. Cet appel de méthode ne dépend pas des paramètres de type du type englobant ou de la méthode.

En outre, l’exemple définit la classe non générique Example . Cette classe a une méthode M qui effectue un appel à une méthode générique.

• Cas 5 : La méthode GM1<Tgm1> générique est appelée, spécifiant Int32 et Object pour les arguments de type du type générique et de la méthode générique, respectivement. Le contexte de cette méthode n’a pas de type générique englobant ou de méthode générique.

Pour chaque cas, l’exemple construit d’abord un MethodInfo qui représente la méthode appelée, puis résout le jeton à l’aide de la ResolveMethod(Int32, Type[], Type[]) surcharge de méthode, à l’aide des méthodes et MethodInfo.GetGenericArguments des Type.GetGenericArguments méthodes pour obtenir les valeurs pour les paramètres et genericMethodArguments les genericTypeArguments paramètres. Cette technique fonctionne dans tous les cas, car les méthodes retournent Type.EmptyTypes pour les contextes non génériques. L’exemple compare la résolution MethodInfo avec la construction MethodInfo.

L’exemple tente ensuite d’utiliser la ResolveMethod(Int32) surcharge de méthode pour résoudre le jeton. Cela fonctionne dans les cas 3, 4 et 5, car les appels de méthode ne dépendent pas du contexte générique. Dans les cas 1 et 2, une exception est levée, car il existe des informations insuffisantes pour résoudre le jeton.

Les valeurs de jeton de métadonnées sont codées en dur en tant qu’énumération. Si vous modifiez cet exemple de code, les valeurs de jeton sont susceptibles de changer. Pour déterminer les nouvelles valeurs de jeton, compilez le code et utilisez Ildasm.exe avec l’option /TOKENS pour examiner l’assembly. Les jetons sont disponibles aux points d’appel. Insérez les nouvelles valeurs dans l’énumération et recompilez l’exemple.

Remarques

Utilisez la Type.GetGenericArguments méthode sur le type où metadataToken se trouve l’étendue pour obtenir un tableau d’arguments de type générique pour genericTypeArguments. Utilisez la MethodInfo.GetGenericArguments méthode sur la méthode dans metadataToken laquelle se trouve l’étendue pour obtenir un tableau d’arguments de type générique pour genericMethodArguments. Il est toujours sûr de fournir ces arguments, même s’ils ne sont pas nécessaires.

Exemples

L’exemple suivant montre comment utiliser les deux surcharges de la ResolveMethod méthode pour résoudre les jetons de métadonnées à partir de sites d’appel dans des contextes génériques et non génériques.

L’exemple de code définit deux types génériques, G1<Tg1> et G2<Tg2> (G1(Of Tg1) et G2(Of Tg2) dans Visual Basic), chacun ayant une méthode générique. G1<Tg1> possède également une méthode non générique qui utilise le paramètre Tg1 de type pour son paramètre. La méthode GM2<Tgm2> générique en type G2<Tg2> contient plusieurs appels de méthode :

• Cas 1 : La méthode GM1<Tgm1> générique est appelée, en utilisant les paramètres de type et GM2<Tgm2>G2<Tg2> en tant qu’arguments de type. En d’autres termes, les types de paramètres de la méthode appelée dépendent des types utilisés pour construire un type générique fermé à partir de la définition de type pour G2<Tg2>.

• Cas 2 : La méthode M1 non générique est appelée. Le paramètre de cette méthode utilise le paramètre de type du type de définition, G1<Tg1>qui est remplacé dans ce cas par le paramètre de type du type englobant, G2<Tg2>.

• Cas 3 : La méthode GM1<Tgm1> générique est appelée, spécifiant Int32 et Object pour les arguments de type du type générique et de la méthode générique, respectivement. Cet appel de méthode ne dépend pas des paramètres de type du type englobant ou de la méthode.

• Cas 4 : La méthode M1 non générique de la Example classe est appelée. Cet appel de méthode ne dépend pas des paramètres de type du type englobant ou de la méthode.

En outre, l’exemple définit la classe non générique Example . Cette classe a une méthode M qui effectue un appel à une méthode générique :

• Cas 5 : La méthode GM1 générique est appelée, spécifiant Int32 et Object pour les arguments de type du type générique et de la méthode générique, respectivement. Le contexte de cette méthode n’a pas de type générique englobant ou de méthode générique.

Pour chaque cas, l’exemple construit d’abord un MethodInfo qui représente la méthode appelée, puis résout le jeton à l’aide de la ResolveMethod(Int32, Type[], Type[]) surcharge de méthode, à l’aide des méthodes et MethodInfo.GetGenericArguments des Type.GetGenericArguments méthodes pour obtenir les valeurs pour les paramètres et genericMethodArguments les genericTypeArguments paramètres. Cette technique fonctionne dans tous les cas, car les méthodes retournent Type.EmptyTypes pour les contextes non génériques. L’exemple compare la résolution MethodInfo avec la construction MethodInfo.

L’exemple tente ensuite d’utiliser la ResolveMethod(Int32) surcharge de méthode pour résoudre le jeton. Cela fonctionne dans les cas 3, 4 et 5, car les appels de méthode ne dépendent pas du contexte générique. Dans les cas 1 et 2, une exception est levée, car il existe des informations insuffisantes pour résoudre le jeton.

Les valeurs de jeton de métadonnées sont codées en dur en tant qu’énumération. Si vous modifiez cet exemple de code, les valeurs de jeton sont susceptibles de changer. Pour déterminer les nouvelles valeurs de jeton, compilez le code et utilisez Ildasm.exe avec l’option /TOKENS pour examiner l’assembly. Les jetons sont disponibles aux points d’appel. Insérez les nouvelles valeurs dans l’énumération et recompilez l’exemple.

Remarques

Pour résoudre un jeton de métadonnées pour une MethodSpec signature dont la signature contient le type ELEMENT_TYPE_VAR d’élément ou ELEMENT_TYPE_MVAR, utilisez la ResolveMethod(Int32, Type[], Type[]) surcharge de méthode, ce qui vous permet de fournir le contexte nécessaire. Autrement dit, lorsque vous résoutz un jeton de métadonnées pour une méthode qui dépend des paramètres de type générique du type générique et/ou de la méthode générique dans laquelle le jeton est incorporé, vous devez utiliser la surcharge qui vous permet de fournir ces paramètres de type.
