关于.net生成静态页面的方法总结
这几天在做国家教育平台阳光工程，由于考虑到将来的用户群比较多，所以我们考虑使用.net生成静态页面的方法来减少数据与数据库的访问量，虽然以前也写过一些静态的页面，但是感觉没有将来的比较复杂，所以搜索了一下网络，再结合自己以前的一些经验，总结出以下几步思想：
1）做一个比较好的模板temp1.html，并在模板中写好题目，内容，作者 以及发布日期的标记，如果还有其他列表的话也要写好其他列表的标记，如 题目可以用标记：$Title$,内容可以用$cont$，发布日期$PubDate，最新发布新闻列表$DtNewest$；
2）设计数据库，可以设置两张表，一张表存放模板，一张用于存放发布新闻的内容
如 模板表： TempTable ： ID ，classid,TempPath(存放模板的路径);
新闻表： NesTable: ID,ClassID,title,cont,Filepath（发布后存放静态页面的路径）,pubdate,author,status;
3）添加新闻时，现在记录添加到新闻表中，然后再根据栏目的ID找到该栏目的模板，把模板中的内容读取到一个字符串变量中，并用新闻表中的字段替换模板中的相应标记，然后调用c#中的读写文件的类，写到一个静态文件中如：News.HTml，写成功后再更新数据中静态文件路径filepath;
这样一个静态文件就写好了
另外本人也从网络上搜集了一些资料，供大家参考（关于新闻内容分页的情况下次叙述）
一、类似的模板
模板页Text.html代码
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
<HEAD>
<title>$ShowArticle$</title>
<body>
$title$
<br>
$author$
<br>
$content$<br>
</body>
</HTML>
