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

Public Sub DrawLines (
	pen As Pen,
	points As PointF()
)

Parameters

pen
Type: System.Drawing.Pen

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

points
Type: System.Drawing.PointF()

Array of PointF structures that represent the points to connect.

Exception Condition
ArgumentNullException

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 PaintEventArgse, 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 Sub DrawLinesPointF(ByVal e As PaintEventArgs)

    ' Create pen.
    Dim blackPen As New Pen(Color.Black, 3)

    ' Create array of points that define lines to draw.
    Dim points As PointF() = {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(blackPen, points)
End Sub
