Remarques

Un tuple est une structure de données qui a un nombre et une séquence de valeurs spécifiques. La Tuple<T1,T2,T3,T4,T5> classe représente un quintuple à 5 tuples, qui est un tuple qui a cinq composants.

Vous pouvez instancier un Tuple<T1,T2,T3,T4,T5> objet en appelant le Tuple<T1,T2,T3,T4,T5> constructeur ou la méthode statique Tuple.Create<T1,T2,T3,T4,T5>(T1, T2, T3, T4, T5) . Vous pouvez récupérer la valeur des composants du tuple à l’aide des propriétés d’instance en lecture seule Item1, Item2, Item3, Item4et Item5 .

Les tuples sont couramment utilisés de quatre façons différentes :

• Pour représenter un ensemble unique de données. Par exemple, un tuple peut représenter un enregistrement de base de données et ses composants peuvent représenter des champs individuels de l’enregistrement.

• Pour fournir un accès facile à un jeu de données et la manipulation de ce jeu de données. L’exemple suivant définit un tableau d’objets Tuple<T1,T2,T3,T4,T5> qui contiennent les noms des running backs dans le football américain, le nombre de matchs auxquels ils ont joué et le nombre de porteurs, de yards totaux gagnés et de touchdowns marqués pendant ces matchs. Le tableau est passé à la méthode, qui calcule le ComputeStatistics nombre de porteurs de chaque running back par match, la moyenne des yards par match, la moyenne des yards par portage et le nombre moyen de touchdowns par tentative.

• Pour retourner plusieurs valeurs d’une méthode sans utiliser de out paramètres (en C#) ou ByRef de paramètres (en Visual Basic). Par exemple, l’exemple précédent retourne ses statistiques calculées, ainsi que le nom du joueur, dans un tableau d’objets Tuple<T1,T2,T3,T4,T5> .

• Pour passer plusieurs valeurs à une méthode via un seul paramètre. Par exemple, la Thread.Start(Object) méthode a un seul paramètre qui vous permet de fournir une valeur à la méthode que le thread exécute au démarrage. Si vous fournissez un Tuple<T1,T2,T3,T4,T5> objet comme argument de méthode, vous pouvez fournir la routine de démarrage du thread avec cinq éléments de données.
