如何在绘制的几个闭合曲线中填充颜色(GDI+)

[mayanmajesty]

我绘制了几条闭合曲线:
g.DrawEllipse(bluePen, ydzbx-10 , ydzby-45 , 20 , 30 );

g.FillEllipse(blueBrush, ydzbx - 10, ydzby - 45, 20, 30);
g.FillEllipse(blueBrush, ydzbx - 10, ydzby + 55, 12, 26);

g.DrawEllipse(bluePen, ydzbx -30, ydzby - 75, 60, 100);
g.DrawEllipse(bluePen, ydzbx -10, ydzby + 55, 12, 26);
g.DrawClosedCurve(bluePen, point1);
g.DrawClosedCurve(bluePen, point2);
g.DrawClosedCurve(bluePen, point3);
g.DrawClosedCurve(bluePen, point4);

椭圆我会填,但是闭合曲线不知道如何填充,我希望的效果是可以象等高线一样,有颜色的渐变!

绘制闭合曲线同时利用 System.Drawing.Drawing2D.GraphicsPath 刻划路径(path), 最后使用path填充背景...

这个渐变我也想知道怎么弄。

g.DrawEllipse(bluePen, ydzbx -10, ydzby + 55, 12, 26);
g.DrawClosedCurve(bluePen, point1);
g.FillEllipse(Brush5, ydzbx - 10, ydzby - 45, 20, 30);
