Examples

L’exemple de code suivant montre comment utiliser l’opérateur Addition.The following code example demonstrates how to use the Addition operator. Pour exécuter cet exemple, collez le code suivant dans un Windows Form.To run this example, paste the following code into a Windows Form. Gérez l’événement Paint du formulaire et appelez opAdditionExampleen passant e en tant que PaintEventArgs.Handle the form's Paint event and call opAdditionExample, passing e as PaintEventArgs.

private void OpAdditionExample(PaintEventArgs e)
{
    PointF point1 = new PointF(120.5F, 120F);
    SizeF size1 = new SizeF(120.5F, 30.5F);
    RectangleF rect1 = new RectangleF(point1, size1);
    if (new PointF(rect1.Right, rect1.Bottom) == point1 + size1)
        e.Graphics.DrawString("They are equal", this.Font, Brushes.Black, rect1);
    else
        e.Graphics.DrawString("They are not equal", this.Font, Brushes.Red, rect1);
}
Private Sub OpAdditionExample(ByVal e As PaintEventArgs) 
    Dim size1 As New SizeF(120.5F, 30.5F)
    Dim point1 As New PointF(20.5F, 20F)
    Dim rect1 As New RectangleF(point1, size1)
    If New PointF(rect1.Right, rect1.Bottom) = point1 + size1 Then
        e.Graphics.DrawString("They are equal", Me.Font, Brushes.Black, rect1)
    Else
        e.Graphics.DrawString("They are not equal", Me.Font, Brushes.Red, rect1)
    End If
 
End Sub

Remarks

L’opérateur Addition ajoute la Width de la taille spécifiée à la coordonnée x du PointF et le Height à la coordonnée y du PointF.The Addition operator adds the Width of the specified size to the x-coordinate of the PointF and the Height to the y-coordinate of the PointF.

La méthode équivalente pour cet opérateur est PointF.Add(PointF, SizeF)The equivalent method for this operator is PointF.Add(PointF, SizeF)

Addition(PointF, Size)

Convertit un PointF selon un Size donné.Translates a PointF by a given Size.

public static System.Drawing.PointF operator + (System.Drawing.PointF pt, System.Drawing.Size sz);
static member ( + ) : System.Drawing.PointF * System.Drawing.Size -> System.Drawing.PointF
Public Shared Operator + (pt As PointF, sz As Size) As PointF

Parameters

pt
PointF

PointF à convertir.The PointF to translate.

sz
Size

Size qui spécifie la paire de nombres à ajouter aux coordonnées de pt.A Size that specifies the pair of numbers to add to the coordinates of pt.

Returns

PointF

Structure PointF convertie.The translated PointF.
