Esempio

Nell'esempio di codice seguente vengono creati punti e dimensioni usando diversi operatori di overload definiti per questi tipi. Viene inoltre illustrato come usare la SystemPens classe .

Questo esempio è progettato per essere usato con Windows Form. Creare un modulo contenente un Button oggetto denominato subtractButton. Incollare il codice nel form e chiamare il CreatePointsAndSizes metodo dal metodo di gestione degli eventi del Paint modulo, passando e come PaintEventArgs.

void CreatePointsAndSizes( PaintEventArgs^ e )
{
   // Create the starting point.
   Point startPoint = Point(subtractButton->Size);
   
   // Use the addition operator to get the end point.
   Point endPoint = startPoint + System::Drawing::Size( 140, 150 );
   
   // Draw a line between the points.
   e->Graphics->DrawLine( SystemPens::Highlight, startPoint, endPoint );
   
   // Convert the starting point to a size and compare it to the
   // subtractButton size.  
   System::Drawing::Size buttonSize = (System::Drawing::Size)startPoint;
   if ( buttonSize == subtractButton->Size )
   {
      e->Graphics->DrawString( "The sizes are equal.", gcnew System::Drawing::Font( this->Font,FontStyle::Italic ), Brushes::Indigo, 10.0F, 65.0F );
   }
}

private void CreatePointsAndSizes(PaintEventArgs e)
{

    // Create the starting point.
    Point startPoint = new Point(subtractButton.Size);

    // Use the addition operator to get the end point.
    Point endPoint = startPoint + new Size(140, 150);

    // Draw a line between the points.
    e.Graphics.DrawLine(SystemPens.Highlight, startPoint, endPoint);

    // Convert the starting point to a size and compare it to the
    // subtractButton size.  
    Size buttonSize = (Size)startPoint;
    if (buttonSize == subtractButton.Size)

        // If the sizes are equal, tell the user.
    {
        e.Graphics.DrawString("The sizes are equal.", 
            new Font(this.Font, FontStyle.Italic), 
            Brushes.Indigo, 10.0F, 65.0F);
    }
}

Private Sub CreatePointsAndSizes(ByVal e As PaintEventArgs)

    ' Create the starting point.
    Dim startPoint As New Point(subtractButton.Size)

    ' Use the addition operator to get the end point.
    Dim endPoint As Point = Point.op_Addition(startPoint, _
        New Size(140, 150))

    ' Draw a line between the points.
    e.Graphics.DrawLine(SystemPens.Highlight, startPoint, endPoint)

    ' Convert the starting point to a size and compare it to the
    ' subtractButton size.  
    Dim buttonSize As Size = Point.op_Explicit(startPoint)
    If (Size.op_Equality(buttonSize, subtractButton.Size)) Then

        ' If the sizes are equal, tell the user.
        e.Graphics.DrawString("The sizes are equal.", _
            New Font(Me.Font, FontStyle.Italic), _
            Brushes.Indigo, 10.0F, 65.0F)
    End If

End Sub
