Nom	Description
Equals(Object)	Retourne une valeur indiquant si cette instance est égale à un objet spécifié.
Equals(UInt16)	Retourne une valeur indiquant si cette instance est égale à une valeur spécifiée UInt16 .

Retourne une valeur indiquant si cette instance est égale 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 à cette instance.

Retours

Boolean

true si obj est une instance de UInt16 cette instance et est égale à la valeur de cette instance ; sinon, false.

Exemples

L’exemple suivant illustre la Equals méthode.

UInt16 myVariable1 = 10;
UInt16 myVariable2 = 10;

//Display the declaring type.
Console.WriteLine("\nType of 'myVariable1' is '{0}' and" +
     " value is :{1}", myVariable1.GetType(), myVariable1);
Console.WriteLine("Type of 'myVariable2' is '{0}' and" +
     " value is :{1}", myVariable2.GetType(), myVariable2);

// Compare 'myVariable1' instance with 'myVariable2' Object.
if (myVariable1.Equals(myVariable2))
    Console.WriteLine("\nStructures 'myVariable1' and " +
          "'myVariable2' are equal");
else
    Console.WriteLine("\nStructures 'myVariable1' and " +
          "'myVariable2' are not equal");

printfn $"\nType of 'myVariable1' is '{myVariable1.GetType()}' and value is :{myVariable1}"

else
    printfn $"\nStructures 'myVariable1' and 'myVariable2' are not equal"

   Dim myVariable1 As UInt16 = UInt16.Parse(10)

Notes pour les appelants

La résolution de surcharge du compilateur peut tenir compte d’une différence apparente dans le comportement des deux Equals(UInt16) surcharges de méthode. Si une conversion implicite entre l’argument obj et un UInt16 est définie et que l’argument n’est pas typé comme un Object, les compilateurs effectuent une conversion implicite et appellent la Equals(UInt16) méthode. Sinon, ils appellent la Equals(Object) méthode, qui retourne false toujours si son obj argument n’est pas une UInt16 valeur. L’exemple suivant illustre la différence de comportement entre les deux surcharges de méthode. Dans le cas d’une Byte valeur, la première comparaison retourne true , car le compilateur effectue automatiquement une conversion étendue et appelle la Equals(UInt16) méthode, tandis que la deuxième comparaison retourne false parce que le compilateur appelle la Equals(Object) méthode.

Remarques

Cette méthode implémente l’interface System.IEquatable<T> et s’exécute légèrement mieux que Equals parce qu’elle n’a pas besoin de convertir le obj paramètre en objet.
