void FillEllipse(
	Brush^ brush,
	RectangleF rect
)

Parameters

brush
Type: System.Drawing::Brush^

Brush that determines the characteristics of the fill.

rect
Type: System.Drawing::RectangleF

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

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 = gcnew 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 = RectangleF(x,y,width,height);

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