练习！！输入学生信息

class Program
{

//定义一个结构体
struct student//student就是我们自己造的新数据类型
{
public int code;//public修饰符
public string name;//结构体的成员
public decimal height;
}

static void Main(string[] args)
{
ArrayList arr = new ArrayList();
for (int i = 0; i < 3; i++)
{
student s = new student();//定义结构体变量
Console.Write("学号：");
s.code = int.Parse(Console.ReadLine());
Console.Write("姓名：");
s.name = Console.ReadLine();
Console.Write("身高：");
s.height = decimal.Parse(Console.ReadLine());

arr.Add(s);
}

for (int i = 0; i < 2; i++)
{
for (int j = i + 1; j < 3; j++)
{
student si = (student)arr[i];
student sj = (student)arr[j];

if (si.height < sj.height)
{
student zhong = si;
arr[i] = arr[j];
arr[j] = zhong;
}
}
}

foreach (student s in arr)
{
Console.WriteLine(s.code + " " + s.name + " " + s.height);
}

//定义一个学生的结构体，学号，姓名，身高，输入学生信息
//按身高排序输出
Console.ReadLine();
}
