Esempio

Nell'esempio di codice seguente vengono creati punti e dimensioni usando molti degli operatori di overload definiti per questi tipi.The following code example creates points and sizes using several of the overloaded operators defined for these types. Viene inoltre illustrato come utilizzare la SystemPens classe.It also demonstrates how to use the SystemPens class.

Questo esempio è progettato per essere usato con Windows Form.This example is designed to be used with Windows Forms. Creare un form che contenga un oggetto Button denominato subtractButton .Create a form that contains a Button named subtractButton. Incollare il codice nel form e chiamare il CreatePointsAndSizes metodo dal Paint metodo di gestione degli eventi del form, passando e come PaintEventArgs .Paste the code into the form and call the CreatePointsAndSizes method from the form's Paint event-handling method, passing e as 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)
