好用的asp.net 分頁(yè)類(lèi) 簡(jiǎn)單好用 支持 Ajax 自定義文字

在做網(wǎng)站沒(méi)用 JS UI控件時(shí) 很實(shí)用

用法：

            var ps=new PageString();            /*可選參數(shù)*/            ps.SetIsEnglish = true;// 是否是英文       (默認(rèn)：false)            ps.SetIsShowText = true;//是否顯示分頁(yè)文字 (默認(rèn)：true)            //ps.TextFormat=""                         (默認(rèn)值：《span class=/"pagetext/"》《strong》總共《/strong》:{0} 條 《strong》當(dāng)前《/strong》:{1}/{2}《/span》)            //ps.SetPageIndexName  Request["pageIndex"](默認(rèn)值："pageIndex")            ps.SetIsAjax = false;//                    (默認(rèn)值："false")            /*函數(shù)參數(shù)*/            int total = 10000;            int pageSize = 10;            int pageIndex = Convert.ToInt32(Request["pageIndex"]);            var page = ps.ToString(total, pageSize, pageIndex, "/UI/PageStringTest.aspx?");            //獲取 page html 輸出           Response.Write(page);

效果：

代碼：
