Retours

true si les rectangles ont les mêmes Location et valeurs Size; sinon, false.

Exemples

L’exemple suivant montre comment utiliser l’opérateur Equality pour déterminer si deux rectangles sont exactement égaux.

private Boolean overloadedEqualityOperatorExample()
{
    // Initialize new rectangle.
    Rect myRectangle = new Rect();

    // The Location property specifies the coordinates of the upper left-hand 
    // corner of the rectangle. 
    myRectangle.Location = new Point(10, 5);

    // Set the Size property of the rectangle with a width of 200
    // and a height of 50.
    myRectangle.Size = new Size(200, 50);

    // Create second rectangle to compare to the first.
    Rect myRectangle2 = new Rect();
    myRectangle2.Location = new Point(0, 0);
    myRectangle2.Size = new Size(200, 50);

    // Check if the two Rects are exactly equal using the overloaded equality operator.
    // areEqual is false because although the size of each rectangle is the same,
    // the locations are different.
    bool areEqual = (myRectangle == myRectangle2);

    // Returns false.
    return areEqual;
}

Private Function overloadedEqualityOperatorExample() As Boolean
    ' Initialize new rectangle.
    Dim myRectangle As New Rect()

    ' The Location property specifies the coordinates of the upper left-hand 
    ' corner of the rectangle. 
    myRectangle.Location = New Point(10, 5)

    ' Set the Size property of the rectangle with a width of 200
    ' and a height of 50.
    myRectangle.Size = New Size(200, 50)

    ' Create second rectangle to compare to the first.
    Dim myRectangle2 As New Rect()
    myRectangle2.Location = New Point(0, 0)
    myRectangle2.Size = New Size(200, 50)

    ' Check if the two Rects are exactly equal using the overloaded equality operator.
    ' areEqual is false because although the size of each rectangle is the same,
    ' the locations are different.
    Dim areEqual As Boolean = (myRectangle = myRectangle2)

    ' Returns false.
    Return areEqual

End Function

Remarques

Cette opération teste l’égalité des objets.

Dans cette comparaison, deux instances de Double.NaN sont considérées comme égales.

La méthode équivalente pour cet opérateur est Rect.Equals(Rect, Rect)
