编写一个控制台程序，他可以接受n个整数类型的命令行参数，要求输出这些数据的和

static void Main(string[] args)
        {
            int sum = 0;
            Console.WriteLine("你想算几个数的和:");
            
            int[] A = new int[i];
            for (i = 0; i < A.Length; i++)
            {
                Console.WriteLine("请输入第{0}个数:", i + 1);
                A[i] = int.Parse(Console.ReadLine());
                sum += A[i];
            }
            Console.WriteLine("这{0}个数的和是{1}:", i, sum);
            Console.ReadLine();

        }
