cms .net webform去服务器控件标签化 pagebase新版本

这是最近在干一个webform的cms的时候用起来的，原来虽然做过很多技术，什么remoting,wcf,webservice，可是弄来弄去，最后也没个收藏的地儿，全都放在笔记本儿上了，可是人又懒地可以，做来做去，最后它们还是扔在那里
。
说正题吧：最近用到的这套小型的cms，主就是用的链表了，大部分的栏目都在同一张表里，而这张表囊括了几乎所有需要用到的字段，包括图片，内容，一堆乱七八糟的东西，这样做的时候主要就是读这一张表，所以这里做的时候主要就是把配置给抽出来。封装的
作用一直都最关键在委托的使用上，从2.0开始，喜欢用委托，可是手写一个又太麻烦从4.0开发就一直用扩展方法和ACTION FUNC等委托，好 好几年未认真写，如今用来还真的是得心应手。表达思想表达地比较迅速，也容量写好。对于一个对代码有追求的人。应该
