Important

Certaines informations portent sur la préversion du produit qui est susceptible d’être en grande partie modifiée avant sa publication. Microsoft exclut toute garantie, expresse ou implicite, concernant les informations fournies ici.

Retourne une valeur qui indique si l'objet Tuple<T1,T2,T3> 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

Boolean

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

Exemples

L’exemple suivant appelle la Tuple<T1,T2,T3>.Equals(Object) méthode pour déterminer si l’un des objets d’un tableau d’objets Tuple<T1,T2,T3> est égal l’un à l’autre. La sortie reflète le fait que la méthode retourne true lors de la Equals(Object) comparaison d’objets Tuple<T1,T2,T3> dont les composants ont des 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> objet.
Ses trois composants sont des mêmes types que l’instance actuelle.
Ses trois 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.
