Graphics.DrawPolygon Method (Pen, PointF[])

.NET Framework 4.6 and 4.5

Draws a polygon defined by an array of PointF structures.

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

Syntax

```public void DrawPolygon(
Pen pen,
PointF[] points
)
```

Parameters

pen
Type: System.Drawing.Pen

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

points
Type: System.Drawing.PointF[]

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

Exceptions

ExceptionCondition
ArgumentNullException

pen is null.

-or-

points is null.

Remarks

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

Examples

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 DrawPolygonPointF(PaintEventArgs e)
{

// Create pen.
Pen blackPen = new Pen(Color.Black, 3);

// Create points that define polygon.
PointF point1 = new PointF(50.0F,  50.0F);
PointF point2 = new PointF(100.0F,  25.0F);
PointF point3 = new PointF(200.0F,   5.0F);
PointF point4 = new PointF(250.0F,  50.0F);
PointF point5 = new PointF(300.0F, 100.0F);
PointF point6 = new PointF(350.0F, 200.0F);
PointF point7 = new PointF(250.0F, 250.0F);
PointF[] curvePoints =
{
point1,
point2,
point3,
point4,
point5,
point6,
point7
};

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