// Create location and size of ellipse.
float x = 0.0F;
float y = 0.0F;
float width = 200.0F;
float height = 100.0F;
// Create start and sweep angles.
float startAngle = 0.0F;
float sweepAngle = 45.0F;
// Draw pie to screen.
e.Graphics.DrawPie(blackPen, x, y, width, height, startAngle, sweepAngle);
}示例2: DrawPieRectangle
public void DrawPieRectangle(PaintEventArgs e)
{
// Create pen.
