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

public void DrawEllipse (
	Pen pen,
	int x,
	int y,
	int width,
	int height
)
public void DrawEllipse (
	Pen pen, 
	int x, 
	int y, 
	int width, 
	int height
)
public function DrawEllipse (
	pen : Pen, 
	x : int, 
	y : int, 
	width : int, 
	height : int
)
Not applicable.

Parameters

pen

Pen that determines the color, width, and style of the ellipse.

x

The x-coordinate of the upper-left corner of the bounding rectangle that defines the ellipse.

y

The y-coordinate of the upper-left corner of the bounding rectangle that defines the ellipse.

width

Width of the bounding rectangle that defines the ellipse.

height

Height of the bounding rectangle that defines the ellipse.

Exception typeCondition

ArgumentNullException

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

This method draws an ellipse that is defined by the bounding rectangle described by the x, y, width, and height parameters.

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 black pen.

  • Creates the position and size of a rectangle to bound an ellipse.

  • Draws the ellipse to the screen.

private void DrawEllipseInt(PaintEventArgs e)
{
    // Create pen.
    Pen blackPen = new Pen(Color.Black, 3);
             
    // Create location and size of ellipse.
    int x = 0;
    int y = 0;
    int width = 200;
    int height = 100;
             
    // Draw ellipse to screen.
    e.Graphics.DrawEllipse(blackPen, x, y, width, height);
}
