Graphics.DrawPolygon Method (Pen, Point[])
.NET Framework (current version)
Draws a polygon defined by an array of Point structures.
Assembly: System.Drawing (in System.Drawing.dll)
Parameters
- pen
-
Type:
System.Drawing.Pen
Pen that determines the color, width, and style of the polygon.
- points
-
Type:
System.Drawing.Point[]
Array of Point structures that represent the vertices of the polygon.
| Exception | Condition |
|---|---|
| ArgumentNullException | pen is null. |
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 PaintEventArgse, 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 = new Pen(Color.Black, 3); // 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.DrawPolygon(blackPen, curvePoints); }
