# DateTime.Equality(DateTime, DateTime) Operator

## Definition

Détermine si deux instances spécifiées de DateTime sont égales.Determines whether two specified instances of DateTime are equal.

``````public:
static bool operator ==(DateTime d1, DateTime d2);``````
``public static bool operator == (DateTime d1, DateTime d2);``
``static member ( = ) : DateTime * DateTime -> bool``
``Public Shared Operator == (d1 As DateTime, d2 As DateTime) As Boolean``

#### Parameters

d1
DateTime

Premier objet à comparer.The first object to compare.

d2
DateTime

Deuxième objet à comparer.The second object to compare.

#### Returns

Boolean

`true` si `d1` et `d2` représentent les mêmes date et heure ; sinon, `false`.`true` if `d1` and `d2` represent the same date and time; otherwise, `false`.

## Examples

L’exemple suivant illustre l’opérateur d’égalité.The following example demonstrates the equality operator.

``````System::DateTime april19( 2001, 4, 19 );
System::DateTime otherDate( 1991, 6, 5 );

// areEqual gets false.
bool areEqual = april19 == otherDate;

otherDate = DateTime( 2001, 4, 19 );
// areEqual gets true.
areEqual = april19 == otherDate;
``````
``````System.DateTime april19 = new DateTime(2001, 4, 19);
System.DateTime otherDate = new DateTime(1991, 6, 5);

// areEqual gets false.
bool areEqual = april19 == otherDate;

otherDate = new DateTime(2001, 4, 19);
// areEqual gets true.
areEqual = april19 == otherDate;
``````
``````Dim april19 As New DateTime(2001, 4, 19)
Dim otherDate As New DateTime(1991, 6, 5)

Dim areEqual As Boolean
' areEqual gets false.
areEqual = DateTime.op_Equality(april19, otherDate)

otherDate = New DateTime(2001, 4, 19)
' areEqual gets true.
areEqual = System.DateTime.op_Equality(april19, otherDate)
``````

## Remarks

L’opérateur Equality détermine si deux valeurs DateTime sont égales en comparant leur nombre de graduations.The Equality operator determines whether two DateTime values are equal by comparing their number of ticks. Avant de comparer des objets DateTime, assurez-vous que les objets représentent des heures dans le même fuseau horaire.Before comparing DateTime objects, make sure that the objects represent times in the same time zone. Vous pouvez le faire en comparant les valeurs de leurs propriétés Kind.You can do this by comparing the values of their Kind property.

La méthode équivalente pour cet opérateur est DateTime.Equals(Object)The equivalent method for this operator is DateTime.Equals(Object)
