.NET Framework Class Library

GraphicsPath..::.AddPolygon Method (array<Point>[]()[])

Adds a polygon to this path.

Namespace: System.Drawing.Drawing2D
Assembly: System.Drawing (in System.Drawing.dll)

Syntax

Visual Basic (Declaration)

Public Sub AddPolygon ( _
    points As Point() _
)

Visual Basic (Usage)

Dim instance As GraphicsPath
Dim points As Point()

instance.AddPolygon(points)

public void AddPolygon(
    Point[] points
)

Visual C++

public:
void AddPolygon(
    array<Point>^ points
)

JScript

public function AddPolygon(
    points : Point[]
)

Parameters

points: Type: array<System.Drawing..::.Point>[]()[]
An array of Point structures that defines the polygon to add.

Remarks

The points in the points array specify the vertices of a polygon. If the first point in the array is not the same as the last point, those two points are connected to close the polygon.

Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, an OnPaint event object. The code performs the following actions:

Creates an array of points that defines a polygon.
Creates a path and adds the polygon to the path.
Draws the path to the screen.

Visual Basic

Public Sub AddPolygonExample(ByVal e As PaintEventArgs)

    ' Create an array of points.
    Dim myArray As Point() = {New Point(23, 20), New Point(40, 10), _
    New Point(57, 20), New Point(50, 40), New Point(30, 40)}

    ' Create a GraphicsPath object and add a polygon.
    Dim myPath As New GraphicsPath
    myPath.AddPolygon(myArray)

    ' Draw the path to the screen.
    Dim myPen As New Pen(Color.Black, 2)
    e.Graphics.DrawPath(myPen, myPath)
End Sub

private void AddPolygonExample(PaintEventArgs e)
{

    // Create an array of points.
    Point[] myArray =
             {
                 new Point(23, 20),
                 new Point(40, 10),
                 new Point(57, 20),
                 new Point(50, 40),
                 new Point(30, 40)
             };

    // Create a GraphicsPath object and add a polygon.
    GraphicsPath myPath = new GraphicsPath();
    myPath.AddPolygon(myArray);

    // Draw the path to the screen.
    Pen myPen = new Pen(Color.Black, 2);
    e.Graphics.DrawPath(myPen, myPath);
}

Visual C++

private:
   void AddPolygonExample( PaintEventArgs^ e )
   {
      // Create an array of points.
      array<Point>^ myArray = {Point(23,20),Point(40,10),Point(57,20),Point(50,40),Point(30,40)};

      // Create a GraphicsPath object and add a polygon.
      GraphicsPath^ myPath = gcnew GraphicsPath;
      myPath->AddPolygon( myArray );

      // Draw the path to the screen.
      Pen^ myPen = gcnew Pen( Color::Black,2.0f );
      e->Graphics->DrawPath( myPen, myPath );
   }
