Exemples

L’exemple suivant définit une classe, StringContainer, qui inclut une collection de chaînes. L’un de ses membres est le délégué CheckAndDisplayDelegate, qui est utilisé pour afficher des chaînes stockées dans un objet StringContainer qui répondent à des critères particuliers. Le délégué prend une chaîne unique en tant que paramètre et retourne void (ou, en Visual Basic, il s’agit d’une procédure Sub). Il inclut également une méthode, DisplayAllQualified, qui a un paramètre unique, un délégué CheckAndDisplayDelegate. Cela permet à la méthode d’être appelée et d’afficher un ensemble de chaînes filtrées en fonction des méthodes que le délégué contient.

L’exemple définit également une classe utilitaire, StringExtensions, qui a deux méthodes :

  • ConStart, qui affiche des chaînes commençant par une consonne.

  • VowelStart, qui affiche des chaînes commençant par une voyelle.

Notez que les deux méthodes incluent un paramètre de chaîne unique et retournent void. En d’autres termes, les deux méthodes peuvent être affectées au délégué CheckAndDisplayDelegate.

La méthode Test.Main est le point d’entrée de l’application. Il instancie un objet StringContainer, le remplit avec des chaînes et crée deux délégués CheckAndDisplayDelegate, conStart et vowelStart, qui appellent une méthode unique. Il appelle ensuite la méthode Delegate.Combine pour créer le délégué multipleDelegates, qui contient initialement les délégués ConStart et VowelStart. Notez que lorsque le délégué multipleDelegates est appelé, il affiche toutes les chaînes de la collection dans leur ordre d’origine. Cela est dû au fait que chaque lettre est transmise séparément à chaque délégué, et chaque lettre répond aux critères de filtrage d’un seul des deux délégués. Enfin, après les appels à Delegate.Remove et Delegate.Combine, multipleDelegates contient deux délégués conStart. Lorsqu’elle est appelée, chaque chaîne de l’objet StringContainer s’affiche deux fois.

Remarques

MulticastDelegate est une classe spéciale. Les compilateurs et d’autres outils peuvent dériver de cette classe, mais vous ne pouvez pas en dériver explicitement. Il en va de même pour la classe Delegate.

Outre les méthodes qui délèguent les types héritent de MulticastDelegate, le Common Language Runtime fournit deux méthodes spéciales : BeginInvoke et EndInvoke. Pour plus d’informations sur ces méthodes, consultez Appel asynchrone de méthodes synchrones.

Une MulticastDelegate a une liste liée de délégués, appelée liste d’appel, composée d’un ou de plusieurs éléments. Lorsqu’un délégué de multidiffusion est appelé, les délégués de la liste d’appel sont appelés de façon synchrone dans l’ordre dans lequel ils apparaissent. Si une erreur se produit pendant l’exécution de la liste, une exception est levée.
