Esempi

Nell'esempio di codice riportato di seguito viene illustrato Addition come utilizzare l'operatore.The following code example demonstrates how to use the Addition operator. Per eseguire questo esempio, incollare il codice seguente in un Windows Form.To run this example, paste the following code into a Windows Form. Gestire l' Paint evento e la chiamata opAdditionExampledel form, e passando PaintEventArgscome.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

Commenti

L' Addition operatore aggiunge l' Width oggetto della dimensione specificata alla Height coordinata x dell'oggetto PointF e alla coordinata y dell'oggetto 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.

Il metodo equivalente per questo operatore èPointF.Add(PointF, SizeF)The equivalent method for this operator is PointF.Add(PointF, SizeF)

Addition(PointF, Size) Addition(PointF, Size) Addition(PointF, Size) Addition(PointF, Size)

Converte un elemento PointF in base a un determinato elemento Size.Translates a PointF by a given Size.
