初次使用集合

using System;
using System.Collections;

class SortSearchDemo
{
     public static void Main()
    {
               ArrayList al=new ArrayList();

                 al.Add(55);
                 al.Add(43);
                 al.Add(-4);
                 al.Add(88);
                 al.Add(3);
                 al.Add(19);

                 al.Sort();

                foreach(int i in al)
               Console.Write(i+"            ");
                Console.ReadLine()   ;

 }
}

Sort()      排序(升)
Clear()    将count设为0以有效的清空队列
