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);
