一個應(yīng)用程序池可以有多個站點，一個站點只對應(yīng)一個應(yīng)用程序池。

編程由來：

存放在一個應(yīng)用程序池里的站點過多就不便于操作，所以需把其中一些站點分配到其他程序池中。

編程題目：

用戶輸入一個數(shù)字或者一個數(shù)字+一個名字。程序?qū)φ军c的所在應(yīng)用程序池進(jìn)行統(tǒng)計，用戶輸入的數(shù)字用于限制應(yīng)用程序池里面的最大容量數(shù)，如果超出該容量，將把超出的站點分配到其他程序應(yīng)用池，或者新建的一個應(yīng)用程序池，把站點分配進(jìn)去。

如果用戶輸入一個數(shù)字的情況，將遍歷所有程序應(yīng)用池；如果用戶輸入一個數(shù)字+一個名字的情況，將只對該名字的應(yīng)用程序池進(jìn)行操作；如果站點的名字和應(yīng)用程序池的名字一樣，將不進(jìn)行操作。

條件：

一、把DefautlAppPool應(yīng)用程序池或者含有字符"AppPool #"的應(yīng)用程序池里面的超出的站點分配到AppPool #?應(yīng)用程序池中（"?"代表數(shù)字）

二、如果aspnet1應(yīng)用程序池里面的網(wǎng)站數(shù)超出用戶限制的數(shù)字，則分配到新建應(yīng)用程序池的命名方式為aspnet1-?;（"?"代表數(shù)字，表示從屬aspnet1下的分支）

三、如二設(shè)置aspnet2，aspnet3，aspnet4應(yīng)用程序池

四、當(dāng)網(wǎng)站名字和應(yīng)用程序池的名字相同時，將不進(jìn)行操作

。。。。。。。。。。。。。。。。。。。。。。。。。。。。。

這是我在公司里面的任務(wù)，以下是我公開的代碼（還不屬于最優(yōu)化的代碼，我把我的制作品拿出來以代表原創(chuàng)性，最優(yōu)化的代碼暫時不公布，如有需要，請聯(lián)系博主?。?/P>
