例

次のコード例は、 Implicit、 RectangleF、および Equality メンバーの使用方法を示しています。 この例は、Windows フォームで使用するように設計されています。 フォームにこのコードを貼り付け、フォームの Paint イベントを処理するときに ConvertRectangleToRectangleF メソッドを呼び出し、eをPaintEventArgsとして渡します。

private:
   void ConvertRectangleToRectangleF( PaintEventArgs^ e )
   {
      // Create a rectangle.
      Rectangle rectangle1 = Rectangle(30,40,50,100);

      // Convert it to a RectangleF.
      RectangleF convertedRectangle = rectangle1;

      // Create a new RectangleF.
      RectangleF rectangle2 = RectangleF(PointF(30.0F,40.0F),SizeF(50.0F,100.0F));

      // Create a custom, partially transparent brush.
      SolidBrush^ redBrush = gcnew SolidBrush( Color::FromArgb( 40, Color::Red ) );

      // Compare the converted rectangle with the new one.  If they 
      // are equal draw and fill the rectangles on the form.
      if ( convertedRectangle == rectangle2 )
      {
         e->Graphics->FillRectangle( redBrush, rectangle2 );
      }

      // Dispose of the custom brush.
      delete redBrush;
   }
};

private void ConvertRectangleToRectangleF(PaintEventArgs e)
{

    // Create a rectangle.
    Rectangle rectangle1 = new Rectangle(30, 40, 50, 100);

    // Convert it to a RectangleF.
    RectangleF convertedRectangle = rectangle1;

    // Create a new RectangleF.
    RectangleF rectangle2 = new RectangleF(new PointF(30.0F, 40.0F),
        new SizeF(50.0F, 100.0F));

    // Create a custom, partially transparent brush.
    SolidBrush redBrush = new SolidBrush(Color.FromArgb(40, Color.Red));

    // Compare the converted rectangle with the new one.  If they 
    // are equal draw and fill the rectangles on the form.
    if (convertedRectangle == rectangle2)
    {
        e.Graphics.FillRectangle(redBrush, rectangle2);
    }

    // Dispose of the custom brush.
    redBrush.Dispose();
}

Private Sub ConvertRectangleToRectangleF( _
    ByVal e As PaintEventArgs)

    ' Create a rectangle.
    Dim rectangle1 As New Rectangle(30, 40, 50, 100)

    ' Convert it to a RectangleF.
    Dim convertedRectangle As RectangleF = _
        RectangleF.op_Implicit(rectangle1)

    ' Create a new RectangleF.
    Dim rectangle2 As New RectangleF(New PointF(30.0F, 40.0F), _
        New SizeF(50.0F, 100.0F))

    ' Create a custom, partially transparent brush.
    Dim redBrush As New SolidBrush(Color.FromArgb(40, Color.Red))

    ' Compare the converted rectangle with the new one.  If they 
    ' are equal, draw and fill the rectangles on the form.
    If (RectangleF.op_Equality(convertedRectangle, rectangle2)) Then
        e.Graphics.FillRectangle(redBrush, rectangle2)
    End If

    ' Dispose of the custom brush.
    redBrush.Dispose()
End Sub
