RectangleF.Equality(RectangleF, RectangleF) Opérateur

Définition

Teste si deux structures RectangleF ont le même emplacement et la même taille.Tests whether two RectangleF structures have equal location and size.

public:
 static bool operator ==(System::Drawing::RectangleF left, System::Drawing::RectangleF right);
public static bool operator == (System.Drawing.RectangleF left, System.Drawing.RectangleF right);
static member ( = ) : System.Drawing.RectangleF * System.Drawing.RectangleF -> bool
Public Shared Operator == (left As RectangleF, right As RectangleF) As Boolean

Paramètres

left
RectangleF

Structure RectangleF qui se trouve à gauche de l'opérateur d'égalité.The RectangleF structure that is to the left of the equality operator.

right
RectangleF

Structure RectangleF qui se trouve à droite de l'opérateur d'égalité.The RectangleF structure that is to the right of the equality operator.

Retours

Boolean

true si les deux structures RectangleF spécifiées ont des propriétés X, Y, Width et Height équivalentes ; sinon, false.true if the two specified RectangleF structures have equal X, Y, Width, and Height properties; otherwise, false.

Exemples

L’exemple de code suivant montre comment utiliser les Implicit RectangleF membres, et Equality .The following code example demonstrates how to use the Implicit, RectangleF and Equality members. Cet exemple est conçu pour être utilisé avec un Windows Form.This example is designed for use with a Windows Form. Collez ce code dans un formulaire et appelez la ConvertRectangleToRectangleF méthode lors du traitement de l’événement du formulaire Paint , e en passant comme PaintEventArgs .Paste this code into a form and call the ConvertRectangleToRectangleF method when handling the form's Paint event, passing e as PaintEventArgs.
