C#之循环的实现方法总结

        static void Main(string[] args)
        {
            int[] hs = { 1,2,3,4,5,6,7,8,9};
            int ligh = hs.Length;
            while (ligh > 0)
            {
                Console.WriteLine(hs[ligh - 1]);
                ligh -= 1;
            }

            Console.ReadKey();
        }    

        static void Main(string[] args)
        {
            int[] hs = { 1,2,3,4,5,6,7,8,9};
            //倒叙打印只需要修改一下判断条件即可
            for (int i = 0; i < hs.Length; i++)
            {
                Console.WriteLine(hs[i].ToString());
            }

            Console.ReadKey();
        }      

        static void Main(string[] args)
        {
            int[] hs = { 1,2,3,4,5,6,7,8,9};
            //这里用到了var关键字，匿名类型(由编译器自动推断)，你可以把它换成int
            foreach (var item in hs)
            {
                Console.WriteLine(item.ToString());
            }

            Console.ReadKey();
        }
