Graphics.FillPolygon Method (Brush, Point[])

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,
	Point[] points
)

Parameters

brush
Type: System.Drawing.Brush

Brush that determines the characteristics of the fill.

points
Type: System.Drawing.Point[]

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

ExceptionCondition
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 PaintEventArgs e, 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 = new SolidBrush(Color.Blue);

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

    // Draw polygon to screen.
    e.Graphics.FillPolygon(blueBrush, curvePoints);
}
