Exemplos

O exemplo de código a seguir demonstra como usar os métodos Round e Truncate.The following code example demonstrates how to use the Round and Truncate methods. Este exemplo foi projetado para uso com um Windows Form.This example is designed for use with a Windows Form. Cole esse código em um formulário e chame o método RoundingAndTruncatingRectangles ao manipular o evento de Paint do formulário, passando e como PaintEventArgs.Paste this code into a form and call the RoundingAndTruncatingRectangles method when handling the form's Paint event, passing e as 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)

    ' 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
