内容分页（编辑器中加分页符）

nt cnv = aa.Content.LastIndexOf("<div style=\"page-break-after: always;\">");
List<article> list_a=null;
if (aa.Section_id == 80 && aa.channel_id == 86)
{
list_a = NepPagerContent(aa.Content.Substring(0, cnv),66,80);//获得分页集合
}else{
list_a=NepPagerContent(aa.Content,1,1);
}
AspNetPager2.RecordCount = list_a.Count;//页数
int sid = AspNetPager2.StartRecordIndex - 1;
int pid = AspNetPager2.PageSize;
contentRe.DataSource = list_a.Skip(sid).Take(pid);//绑定到页面
contentRe.DataBind();
