关于权限设计的一点建议

static void Main(string[] args)
        {

            while (true)
            {
                Console.WriteLine("输入数字：");
                List<int> lst = new List<int>();
                GetNum(int.Parse(Console.ReadLine()), lst);
                Console.WriteLine("结果：" + string.Join(" ", lst));
            }


            Console.ReadKey();
        }

        private static void GetNum(int intNum, List<int> lst)
        {
            if (intNum <= 0)
                return;

            double dec = Math.Log(intNum) / Math.Log(2);
            int intMax = (int)dec;
            int intMaxNum = (int)Math.Pow(2, intMax);
            lst.Add(intMaxNum);
            intNum = intNum - intMaxNum;

            GetNum(intNum, lst);
        }
