• Asp.net 生成静态页面


    http://www.cnblogs.com/tonycall/archive/2009/07/18/1526079.html

          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)

          部分代码:
