如何用重叠曲线填充 GraphicsPath？

using System.Drawing;
using System.Drawing.Drawing2D;

public void DrawGraphicsPath(Graphics g)
{
    // 创建一个 GraphicsPath 对象
    GraphicsPath path = new GraphicsPath();

    // 添加曲线
    path.AddCurve(new Point[] {
        new Point(50, 200),
        new Point(100, 100),
        new Point(150, 200),
        new Point(200, 100),
        new Point(250, 200)
    });

    // 添加连接线
    path.AddLine(new Point(250, 200), new Point(300, 100));

    // 添加弧形
    path.AddArc(new Rectangle(350, 50, 100, 100), 0, 360);

    // 添加另一个 GraphicsPath 对象
    GraphicsPath path2 = new GraphicsPath();
    path2.AddEllipse(new Rectangle(450, 200, 100, 100));
    path.AddPath(path2, true);

    // 填充 GraphicsPath 对象
    using (Brush brush = new SolidBrush(Color.Red))
    {
        g.FillPath(brush, path);
    }
}
