指定概率根据随机数执行操作 和苹果机游戏差不多的

public class demo

    {

        private string _name;



        public string Name

        {

            get { return _name; }

            set { _rate = value; }

        }





        public demo(string name, int rate) { _name = name; _rate = rate; }



    }

                }
