Graphics.DrawLines Method (Pen, PointF[])

Draws a series of line segments that connect an array of PointF structures.

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

public void DrawLines(
	Pen pen,
	PointF[] points


Type: System.Drawing.Pen
Pen that determines the color, width, and style of the line segments.
Type: System.Drawing.PointF[]
Array of PointF structures that represent the points to connect.


pen is null.


points is null.

This method draws a series of lines connecting an array of ending points. The first two points in the array specify the first line. Each additional point specifies the end of a line segment whose starting point is the ending point of the previous line segment.

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:

  • Code creates a black pen.

  • Creates an array of points of segments of the line.

  • Draws the connected line segments to the screen.

public void DrawLinesPointF(PaintEventArgs e)

    // Create pen.
    Pen pen = new Pen(Color.Black, 3);

    // Create array of points that define lines to draw.
    PointF[] points =
                 new PointF(10.0F,  10.0F),
                 new PointF(10.0F, 100.0F),
                 new PointF(200.0F,  50.0F),
                 new PointF(250.0F, 300.0F)

    //Draw lines to screen.
    e.Graphics.DrawLines(pen, points);
