Exemples

L’exemple suivant émet un assembly dynamique et l’enregistre dans le répertoire actif. Lorsque l’assembly est créé, la SetPublicKeyToken méthode est utilisée pour définir le jeton de clé publique de l’assembly. La GetPublicKeyToken méthode est ensuite utilisée pour récupérer le jeton de clé publique, qui s’affiche dans la console.

Remarques

Lorsque vous définissez la clé publique en appelant la SetPublicKey méthode, vous devez également utiliser la SetPublicKeyToken méthode pour fournir un jeton de clé publique. Sinon, un SecurityException est levée lorsque la GetPublicKey méthode est appelée.
