将一整数逆序，如987654321变为123456789。

static void Main(string[] args)
{
int[] numbers = new int[] { 9, 8, 7, 6, 5, 4, 3, 2, 1 };
for (int i = numbers.Length - 1; i >= 0; i--)
{
var dd = numbers[i];
Console.WriteLine(dd);
}
int[] newArrary = numbers.Reverse().ToArray();
foreach (var n in newArrary)
{
Console.WriteLine(n);
}
Console.ReadLine();
}
