public void DrawLines (
	Pen pen,

)
public function DrawLines (

Parameters

pen

Pen that determines the color, width, and style of the line segments.

points

Array of Point structures that represent the points to connect.

Exception typeCondition

ArgumentNullException

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

-or-

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

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 PaintEventArgse, which is a parameter of the Paint event handler. The code performs the following actions:

  • Creates a black pen.

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

  • Draws the connected line segments to the screen.

public void DrawLinesPoint(PaintEventArgs e)
{
             
    // Create pen.
    Pen pen = new Pen(Color.Black, 3);
             
    // Create array of points that define lines to draw.
    Point[] points =
             {
                 new Point(10,  10),
                 new Point(10, 100),
                 new Point(200,  50),
                 new Point(250, 300)
             };
             
    //Draw lines to screen.
    e.Graphics.DrawLines(pen, points);
}

public void DrawLinesPoint(PaintEventArgs e) 
{
    // Create pen.
    Pen pen =  new Pen(Color.get_Black(), 3);

    // Create array of points that define lines to draw.
    Point points[] =  {new Point(10, 10), new Point(10, 100), 
                        new Point(200, 50), new Point(250, 300)};

    //Draw lines to screen.
    e.get_Graphics().DrawLines(pen, points);
} //DrawLinesPoint
