Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following actions:

Creates a black pen.
Creates the position and size of a rectangle to bound an ellipse.
Draws the ellipse to the screen.

C++

private void DrawEllipseInt(PaintEventArgs e)
{
    // Create pen.
    Pen blackPen = new Pen(Color.Black, 3);

    // Create location and size of ellipse. 
    int x = 0;
    int y = 0;
    int width = 200;
    int height = 100;

    // Draw ellipse to screen.
    e.Graphics.DrawEllipse(blackPen, x, y, width, height);
}
