c#之数组的遍历

            static void Main(string[] args)
           {
            int[] arr = { 10, 11, 12, 13, 14 };
            //方法1
            //for (int i = 0; i < arr.Length; i++)
            //{
            //    Console.WriteLine(arr[i]);
            //}

            //方法2
            //int i = 0;
            //while (i < arr.Length)
            //{
            //    Console.WriteLine(arr[i]);
            //    i++;
            //}
            


            //方法3 
            foreach (int  s in arr)
            {
                Console.WriteLine(s);
            }
