一个应用程序池可以有多个站点，一个站点只对应一个应用程序池。

编程由来：存放在一个应用程序池里的站点过多就不便于操作，所以需把其中一些站点分配到其他程序池中。

编程题目：用户输入一个数字或者一个数字+一个名字。

程序对站点的所在应用程序池进行统计，用户输入的数字用于限制应用程序池里面的最大容量数，如果超出该容量，将把超出的站点分配到其他程序应用池，或者新建的一个应用程序池，把站点分配进去。

如果用户输入一个数字的情况，将遍历所有程序应用池；如果用户输入一个数字+一个名字的情况，将只对该名字的应用程序池进行操作；如果站点的名字和应用程序池的名字一样，将不进行操作。

条件：一、把DefautlAppPool应用程序池或者含有字符"AppPool #"的应用程序池里面的超出的站点分配到AppPool #?应用程序池中（"?"代表数字）二、如果aspnet1应用程序池里面的网站数超出用户限制的数字，则分配到新建应用程序池的命名方式为aspnet1-?;（"?"代表数字，表示从属aspnet1下的分支）三、如二设置aspnet2，aspnet3，aspnet4应用程序池四、当网站名字和应用程序池的名字相同时，将不进行操作。

这是我在公司里面的任务，以下是我公开的代码（还不属于最优化的代码，我把我的制作品拿出来以代表原创性，最优化的代码暂时不公布，如有需要，请联系博主！）。
