Graphics.DrawPolygon Method (Pen, Point())

Draws a polygon defined by an array of Point structures.

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

'Declaration
Public Sub DrawPolygon ( _
	pen As Pen, _
	points As Point() _
)

Parameters

pen
Type: System.Drawing.Pen

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

points
Type: System.Drawing.Point()

Array of Point structures that represent the vertices of the polygon.

ExceptionCondition
ArgumentNullException

pen is Nothing.

Every pair of two consecutive points in the array specifies a side of the polygon. In addition, if the last point and the first point of the array do not coincide, they specify the last side of the polygon.

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:

  • Creates a black pen.

  • Creates an array of seven points for the vertices of the polygon.

  • Draws the polygon to the screen.

Public Sub DrawPolygonPoint(ByVal e As PaintEventArgs)

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

    ' Create points that define polygon. 
    Dim point1 As New Point(50, 50)
    Dim point2 As New Point(100, 25)
    Dim point3 As New Point(200, 5)
    Dim point4 As New Point(250, 50)
    Dim point5 As New Point(300, 100)
    Dim point6 As New Point(350, 200)
    Dim point7 As New Point(250, 250)
    Dim curvePoints As Point() = {point1, point2, point3, point4, _
    point5, point6, point7}

    ' Draw polygon to screen.
    e.Graphics.DrawPolygon(blackPen, curvePoints)
End Sub
