Asp.net 生成静态页面

浏览数：27 / 时间：2015年06月09日

第一次发表，有什么错误，请大家谅解噢！

如果不明白的话，建议自己拷一次。就会的了。。

开发步骤：

1、路径映射类(UrlMapping)，主要对路径进行拆分、拼接。（关键的一步）

2、过滤流类(FilterStream)，主要负责生成静态页面。

3、静态页面类(HtmlPage)，主要是调用UrlMapping和FilterStream类，

哪个页面想静态化，就继承这个类。

4、HtmlHandler类，路径后缀为Html的，都由它来处理，与HtmlPage类相似。

5、HtmlPanel类（控件），页面带上这个控件，超链接会静态化。(详情请下载源码包）
