用c#调用两个类随意输入三个数比较大小按顺序输出的代码

我这个随便输入几数的，从小到大排．
using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication29
{
class Program
{
static void Main(string[] args)
{
Console.Write("输入数:");
string[] s = Console.ReadLine().Split();
int len = s.Length;
int[] Int = new int[len];
for (int i = 0; i < s.Length; i++)
{
Int[i] = Convert.ToInt32(s[i]);
}
Array.Sort(Int);
foreach (int t in Int)
{
Console.Write(t + " ");
}
Console.ReadLine();
}
}
}

啊

static void Main(string[] args)
{
int[] a = new int[3];
for (int i = 0; i < a.Length; i++)
a[i]
