asp.net新闻列表生成静态页之批量和单页生成
时间：2021-01-12 13:20:47|栏目：.NET代码|点击： 次
大家都知道，生成静态页的方法有两种，第一种是使用C#在后台硬编码，第二种是读取模板文件，使用字符串代替。总体来讲第一种方法代码量比较大，维护起来有点困难。生成静态页的目的是为了提高用户体验度，加快访问速度。
使用静态页面还有如下好处：
1、 安全：使用静态页面，用户访问的使没有任何操作功能的html页面，可以说从安全性方面大大提高了程序及服务器的安全。
2、 快速：用户访问的是提前生成好的静态页面，使用户对页面的请求瓶颈只受IO的限制而不会有其他方面的影响。
3、 降低服务器，数据库负载：因为用户访问的是静态页，对承载静态页的服务器配置要求降低了许多，同时，不会因为过大的访问量，造成数据库服务器负载过重等问题。
下面分享asp.net新闻列表生成静态页之批量和单页生成。前期准备，需要新建一个文件夹。。前台展示:/new/default.aspx 这个页面放的就是动态的新闻列表数据。
先看下图：
不多说了上代码
这里要说明一下，我用的AspNetPager分页控件，需要设置一下
<webdiyer:AspNetPager ID="AspNetPager1" runat="server" FirstPageText="首页"
LastPageText="末页" NextPageText="下一页" NumericButtonCount="10"
OnLoad="AspNetPager1_Load" OnPageChanged="AspNetPager1_PageChanged1"
PageSize="13" PrevPageText="上一页" Font-Bold="False" Font-Size="13px"
CssClass="badoo" UrlPaging="true" CurrentPageButtonPosition="Center"
PagingButtonSpacing="5px" EnableUrlRewriting="True"
UrlRewritePattern="news_{0}.html" ShowMoreButtons="False"
ShowPageIndexBox="Never" >
</webdiyer:AspNetPager>
需要设置三个地方：
UrlPaging="true" 设置启用url来传递分页信息 EnableUrlRewriting="True" 启用URL重写 UrlRewritePattern="news_{0}.html" 设置分页URL重写格式
