Örnekler

Aşağıdaki kod örneği, işlecinin Addition nasıl kullanılacağını gösterir. Bu örneği çalıştırmak için aşağıdaki kodu bir Windows Formu'na yapıştırın. Formun Paint olayını işleyip olarak geçirerek ePaintEventArgsçağrısı opAdditionExampleyapın.

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)

Açıklamalar

Addition işleci Width belirtilen boyutun x koordinatını PointF ve Height y koordinatını PointFekler.

Bu işlecin eşdeğer yöntemi şudur: PointF.Add(PointF, SizeF)
