好用的asp.net 分页类 简单好用 支持 Ajax 自定义文字

在做网站没用 JS UI控件时 很实用

用法：

            var ps=new PageString();            /*可选参数*/            ps.SetIsEnglish = true;// 是否是英文       (默认：false)            ps.SetIsShowText = true;//是否显示分页文字 (默认：true)            //ps.TextFormat=""                         (默认值：《span class=\"pagetext\"》《strong》总共《/strong》:{0} 条 《strong》当前《/strong》:{1}/{2}《/span》)            //ps.SetPageIndexName  Request["pageIndex"](默认值："pageIndex")            ps.SetIsAjax = false;//                    (默认值："false")            /*函数参数*/            int total = 10000;            int pageSize = 10;            int pageIndex = Convert.ToInt32(Request["pageIndex"]);            var page = ps.ToString(total, pageSize, pageIndex, "/UI/PageStringTest.aspx?");            //获取 page html 输出           Response.Write(page);

效果：
