Exempel
I följande kodexempel visas hur du använder Implicitmedlemmarna , RectangleFoch Equality . Det här exemplet är utformat för användning med ett Windows formulär. Klistra in den här koden i ett formulär och anropa ConvertRectangleToRectangleF metoden när du hanterar formulärets Paint händelse och skicka e som PaintEventArgs.
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();
