C#winform程序自定义鼠标样式

 public void SetCursor(Bitmap cursor, Point hotPoint)
        {
            int hotX = hotPoint.X;
            int hotY = hotPoint.Y;
            Bitmap myNewCursor = new Bitmap(cursor.Width *  - hotX, cursor.Height *  - hotY);
            Graphics g = Graphics.FromImage(myNewCursor);
            g.Clear(Color.FromArgb(, , , ));
            g.DrawImage(cursor, cursor.Width - hotX, cursor.Height - hotY, cursor.Width,
            cursor.Height);

            this.Cursor = new Cursor(myNewCursor.GetHicon());

            g.Dispose();
            myNewCursor.Dispose();
        }
        private void Form1_Load(object sender, EventArgs e)
        {
             //传入鼠标自定义位图
            Bitmap a = (Bitmap)Bitmap.FromFile("锤子.png");
           //调用函数
            SetCursor(a, new Point(, ));
        }
