Namespace:   System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

public void FillEllipse(
	Brush brush,
	RectangleF rect


Type: System.Drawing.Brush

Brush that determines the characteristics of the fill.

Type: System.Drawing.RectangleF

RectangleF structure that represents the bounding rectangle that defines the ellipse.

Exception Condition

brush is null.

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 PaintEventArgse, 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);
