Graphics.DrawPolygon Method (Pen, PointF[])
.NET Framework 2.0
Draws a polygon defined by an array of PointF structures.
Namespace: System.Drawing
Assembly: System.Drawing (in system.drawing.dll)
Assembly: System.Drawing (in system.drawing.dll)
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 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 ); }
public void DrawPolygonPointF(PaintEventArgs e)
{
// Create pen.
Pen blackPen = new Pen(Color.get_Black(), 3);
// Create points that define polygon.
PointF point1 = new PointF(50, 50);
PointF point2 = new PointF(100, 25);
PointF point3 = new PointF(200, 5);
PointF point4 = new PointF(250, 50);
PointF point5 = new PointF(300, 100);
PointF point6 = new PointF(350, 200);
PointF point7 = new PointF(250, 250);
PointF curvePoints[] = { point1, point2, point3, point4, point5,
point6, point7};
// Draw polygon curve to screen.
e.get_Graphics().DrawPolygon(blackPen, curvePoints);
} //DrawPolygonPointF
