class Program
    {
        public void Count(int inVal)
        {
            if (inVal==0)
            return;
            Count(inVal-1);
            Console.WriteLine("{0}", inVal);
        }
        static void Main(string[] args)
        {
            Program pr = new Program();
            pr.Count(4);
        }
    }
为什么输出的是1 2 3 而不是3 2 1
