heart shaped picturebox

问题

Is it possible to make a heart shaped picturebox in c#? I have seen codes in making rectangle and ellipse but I don't have any idea on making a heart shaped region.

Any idea?

This seems to work:

public class HeartPictureBox : PictureBox {
    protected override void OnPaint(PaintEventArgs pe) {
        using (System.Drawing.Drawing2D.GraphicsPath path = new System.Drawing.Drawing2D.GraphicsPath()) {
            path.AddBezier(this.Width >> 1,
                            this.Height >> 2,
                            this.Width * 1.25f, 0f,
                            this.Width,
                            this.Height * 0.75f,
                            this.Width >> 1,
                            this.Height);
            path.AddBezier(this.Width >> 1,
                            this.Height >> 2,
                            -this.Width * .25f, 0f,
                            0f,
                            this.Height * 0.75f,
                            this.Width >> 1,
                            this.Height);

            this.Region = new Region(path);
        }
    }
}

using System;
namespace ConsoleApplication6
{
    class Program
    {
        static void Main()
        {
            Console.WriteLine("    o o.o o   ");
            Console.WriteLine("  o         o      ");
            Console.WriteLine("  o         o       ");
            Console.WriteLine("   o       o         ");
            Console.WriteLine("     o    o       ");
            Console.WriteLine("       o         ");
            Console.ReadKey();
        }
  }}
