Exemples

L'exemple de code suivant montre une méthode substituée PartCommunicationInit qui crée une instance de la classe ParametersOutProviderInitEventArgs pour définir les paramètres qui seront transmis dans l'événement ParametersOutProviderInit . Cet exemple de code fait partie d'un exemple plus développé fourni pour l'interface IParametersOutProvider .
