Fills the interior of a polygon defined by an array of points specified by Point structures.

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

public:
void FillPolygon(
	Brush^ brush,
	array<Point>^ points
)

Parameters

brush
Type: System.Drawing::Brush^

Brush that determines the characteristics of the fill.

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

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

Exception Condition
ArgumentNullException

brush is null.

-or-

points is null.

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

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 solid blue brush.

  • Creates an array of seven points to define a polygon.

  • Fills the polygonal area on the screen.

public:
   void FillPolygonPoint( PaintEventArgs^ e )
   {
      // Create solid brush.
      SolidBrush^ blueBrush = gcnew SolidBrush( Color::Blue );

      // 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->FillPolygon( blueBrush, curvePoints );
   }
