Tuple<T1,T2,T3,T4,T5>.Equals(Object) Méthode

Définition

Retourne une valeur qui indique si l'objet Tuple<T1,T2,T3,T4,T5> actuel est égal à un objet spécifié.

public:
 override bool Equals(System::Object ^ obj);
public override bool Equals (object obj);
public override bool Equals (object? obj);
override this.Equals : obj -> bool
Public Overrides Function Equals (obj As Object) As Boolean

Paramètres

obj
Object

Objet à comparer avec cette instance.

Retours

true si l'instance actuelle est égale à l'objet spécifié ; sinon, false.

Exemples

L’exemple suivant définit un tableau d’objets à 5 tuples qui contiennent des données sur les températures des patients dans deux groupes de test. Le premier composant du tableau fournit le numéro du groupe de test, et les deuxièmes à cinquième composants fournissent les températures d’un patient à intervalles horaires. La Tuple<T1,T2,T3,T4,T5>.Equals(Object) méthode est appelée pour comparer chaque Tuple<T1,T2,T3,T4,T5> objet à tous les autres Tuple<T1,T2,T3,T4,T5> objets. La sortie montre que la Equals méthode retourne true uniquement lorsque les cinq composants des objets ont des Tuple<T1,T2,T3,T4,T5> valeurs égales.

Remarques

Le obj paramètre est considéré comme égal à l’instance actuelle dans les conditions suivantes :

  • Il s’agit d’un Tuple<T1,T2,T3,T4,T5> objet.

  • Ses cinq composants sont des mêmes types que l’instance actuelle.

  • Ses cinq composants sont égaux à ceux de l’instance actuelle. L'égalité est déterminée par le comparateur d'égalité d'objet par défaut pour chaque composant.
