Graphics::DrawPolygon Method (Pen, array<Point>)

Draws a polygon defined by an array of Point structures.

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

public:
void DrawPolygon(
	Pen^ pen, 
	array<Point>^ points
)

Parameters

pen
Type: System.Drawing::Pen

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

points
Type: array<System.Drawing::Point>

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

ExceptionCondition
ArgumentNullException

pen is nullptr.

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:
   void DrawPolygonPoint( PaintEventArgs^ e )
   {
      // Create pen.
      Pen^ blackPen = gcnew Pen( Color::Black,3.0f );

      // Create points that define polygon.
      Point point1 = Point(50,50);
      Point point2 = Point(100,25);
      Point point3 = Point(200,5);
      Point point4 = Point(250,50);
      Point point5 = Point(300,100);
      Point point6 = Point(350,200);
      Point point7 = Point(250,250);
      array<Point>^ curvePoints = {point1,point2,point3,point4,point5,point6,point7};

      // Draw polygon to screen.
      e->Graphics->DrawPolygon( blackPen, curvePoints );
   }
