Örnekler

Aşağıdaki kod örneğinde ve Truncate yöntemlerinin Round nasıl kullanılacağı gösterilmektedir. Bu örnek, Bir Windows Formu ile kullanılmak üzere tasarlanmıştır. Bu kodu bir forma yapıştırın ve formun RoundingAndTruncatingRectanglesPaint olayını işlerken yöntemini çağırın e ve olarak geçirin PaintEventArgs.

private:
   void RoundingAndTruncatingRectangles( PaintEventArgs^ e )
   {
      // Construct a new RectangleF.
      RectangleF myRectangleF = RectangleF(30.6F,30.7F,40.8F,100.9F);

      // Call the Round method.
      Rectangle roundedRectangle = Rectangle::Round( myRectangleF );

      // Draw the rounded rectangle in red.
      Pen^ redPen = gcnew Pen( Color::Red,4.0f );
      e->Graphics->DrawRectangle( redPen, roundedRectangle );

      // Call the Truncate method.
      Rectangle truncatedRectangle = Rectangle::Truncate( myRectangleF );

      // Draw the truncated rectangle in white.
      Pen^ whitePen = gcnew Pen( Color::White,4.0f );
      e->Graphics->DrawRectangle( whitePen, truncatedRectangle );

      // Dispose of the custom pens.
      delete redPen;
      delete whitePen;
   }

private void RoundingAndTruncatingRectangles(PaintEventArgs e)
{

    // Construct a new RectangleF.
    RectangleF myRectangleF = 
        new RectangleF(30.6F, 30.7F, 40.8F, 100.9F);

    // Call the Round method.
    Rectangle roundedRectangle = Rectangle.Round(myRectangleF);

    // Draw the rounded rectangle in red.
    Pen redPen = new Pen(Color.Red, 4);
    e.Graphics.DrawRectangle(redPen, roundedRectangle);

    // Call the Truncate method.
    Rectangle truncatedRectangle = Rectangle.Truncate(myRectangleF);

    // Draw the truncated rectangle in white.
    Pen whitePen = new Pen(Color.White, 4);
    e.Graphics.DrawRectangle(whitePen, truncatedRectangle);

    // Dispose of the custom pens.
    redPen.Dispose();
    whitePen.Dispose();
}

Private Sub RoundingAndTruncatingRectangles( _
    ByVal e As PaintEventArgs)

    ' Construct a new RectangleF.
    Dim myRectangleF As New RectangleF(30.6F, 30.7F, 40.8F, 100.9F)

    ' Call the Round method.
    Dim roundedRectangle As Rectangle = Rectangle.Round(myRectangleF)

    ' Draw the rounded rectangle in red.
    Dim redPen As New Pen(Color.Red, 4)
    e.Graphics.DrawRectangle(redPen, roundedRectangle)

    ' Call the Truncate method.
    Dim truncatedRectangle As Rectangle = _
        Rectangle.Truncate(myRectangleF)

    ' Draw the truncated rectangle in white.
    Dim whitePen As New Pen(Color.White, 4)
    e.Graphics.DrawRectangle(whitePen, truncatedRectangle)

    ' Dispose of the custom pens.
    redPen.Dispose()
    whitePen.Dispose()
End Sub
