Graphics::DrawPolygon Method (Pen, array<PointF>)
Visual Studio 2010
Draws a polygon defined by an array of PointF 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: array<System.Drawing::PointF>
Array of PointF structures that represent the vertices of the polygon.
| Exception | Condition |
|---|---|
| ArgumentNullException | pen is nullptr. -or- points is nullptr. |
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 = gcnew Pen( Color::Black,3.0f ); // Create points that define polygon. PointF point1 = PointF(50.0F,50.0F); PointF point2 = PointF(100.0F,25.0F); PointF point3 = PointF(200.0F,5.0F); PointF point4 = PointF(250.0F,50.0F); PointF point5 = PointF(300.0F,100.0F); PointF point6 = PointF(350.0F,200.0F); PointF point7 = PointF(250.0F,250.0F); array<PointF>^ curvePoints = {point1,point2,point3,point4,point5,point6,point7}; // Draw polygon curve to screen. e->Graphics->DrawPolygon( blackPen, curvePoints ); }
