This method fills the interior of an ellipse with a Brush. The ellipse is defined by the bounding rectangle represented by the rect parameter.

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);
