新手学习c# 在博客园上看到后自己模仿打出来的第一个程序  开心,纪念一下

bean :食物类

block :蛇块类

snake :蛇类

Map :地图 图形类

 食物类:

class bean
    {
        private Point _origin;//用于画食物顶端坐标

        public Point Origin//封装字段
        {
            get { return _origin; }
            set { _origin = value; }
        }
        //显示食物方法
        public void showBean(Graphics g)
        {
            //定义红色画笔
            SolidBrush brush = new SolidBrush(Color.Red);
            //用实心矩形画食物
            g.FillRectangle(brush, _origin.X, _origin.Y, 15, 15);
        }
        //食物消失方法
        public void unShowBean(Graphics g)
        {
            //定义背景色画笔
            SolidBrush brush = new SolidBrush(Color.Red);
            //用实心矩形画食物
            g.FillRectangle(brush, _origin.X, _origin.Y, 15, 15);
        }
    }

蛇块类:2020-02-16

             }
             g.DrawImage(bitMap, Origin.X, Origin.Y, 15, 15);
         }
         //蛇块消除
         public void UnShowBlock(Graphics g)
