c#排序及反向打印数组

Console.WriteLine ("请输入你希望排序_____个年龄(整数类型）：");

int sum = int.Parse (Console.ReadLine ());

Console.WriteLine ("请输入{0}个年龄（整数类型）：", sum);

//初始化数组，给每一个输入数据存入当前创建的数组

int[] arr = new int[sum];

arr [i] = int.Parse (Console.ReadLine ());

}

for (int i = 0; i < arr.Length - 1; i++) {

//反向遍历

Array.Reverse (arr);
