Exemple de sortie :

The first package contains 1 executables

The first package now contains 0 executables

The second package initially contains 0 executables

The second package now contains 1 executables

Remarques

Si l’appel à la Contains méthode retourne true, vous pouvez accéder à l’élément spécifié dans la collection en utilisant la syntaxe Executables[index]. Si le Contains retourne false, cette propriété crée une exception. En C#, cette propriété est l’indexeur de la Executables classe.
