一個(gè)應(yīng)用程序池可以有多個(gè)站點(diǎn)，一個(gè)站點(diǎn)只對(duì)應(yīng)一個(gè)應(yīng)用程序池。

創(chuàng)新互聯(lián)主要從事成都網(wǎng)站制作、成都網(wǎng)站設(shè)計(jì)、網(wǎng)頁設(shè)計(jì)、企業(yè)做網(wǎng)站、公司建網(wǎng)站等業(yè)務(wù)。立足成都服務(wù)邊壩,10余年網(wǎng)站建設(shè)經(jīng)驗(yàn),價(jià)格優(yōu)惠、服務(wù)專業(yè),歡迎來電咨詢建站服務(wù):18980820575

編程由來：

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

編程題目：

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

如果用戶輸入一個(gè)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(gè)數(shù)字+一個(gè)名字的情況，將只對(duì)該名字的應(yīng)用程序池進(jìn)行操作；如果站點(diǎn)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(diǎn)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(shí)，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(shí)不公布，如有需要，請(qǐng)聯(lián)系博主?。?/p>
