Asp.net C#生成静态网页实例
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>
