ArgumentNullException

brush is a null reference (Nothing in Visual Basic).

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);
}

public void FillEllipseRectangleF(PaintEventArgs e) 
{
    // Create solid brush.
    SolidBrush redBrush =  new SolidBrush(Color.get_Red());

    // Create rectangle for ellipse.
    float x = 0;
    float y = 0;
    float width = 200;
    float height = 100;
    RectangleF rect =  new RectangleF(x, y, width, height);

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