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 solid red brush.

  • Creates a rectangle that bounds an ellipse.

  • Fills the ellipse on the screen.

public void FillEllipseRectangleF(PaintEventArgs e)
{

    // Create solid brush.
    SolidBrush redBrush = new SolidBrush(Color.Red);

    // Create rectangle for ellipse. 
    float x = 0.0F;
    float y = 0.0F;
    float width = 200.0F;
    float height = 100.0F;
    RectangleF rect = new RectangleF(x, y, width, height);

    // Fill ellipse on screen.
    e.Graphics.FillEllipse(redBrush, rect);
}
