asp.net中将DataTable根据xslt生成html静态页面，支持分页

功能很单一，也不是很完善~~，虚心听各位的教诲*^_^*
代码如下：

有两种使用方法。
第一种：实例化时初始化数据，例：

        private void Page_Load(object sender, System.EventArgs e)
        {
            // 在此处放置用户代码以初始化页面
            string strSql="Select c.CRM_ID,c.crm_cn,c.CRM_TYPE_ID login_name From crm c Where c.status='0'";
            OracleDb conn=new OracleDb();
            DataTable dt=new DataTable();
            dt=conn.GetDtRecorder(strSql);
            string strAPath=Request.PhysicalApplicationPath;
            string strXmlname=strAPath+"xsltdemo\\crm.xml";
            string strHtmlname=strAPath+"xsltdemo\\crm.html";
            string strXSLTname=strAPath+"xsltdemo\\crm.xslt";
            xmlhtml sh=new xmlhtml(dt,strXmlname,strHtmlname,strXSLTname,100);
            sh.StaticHtml();
            sh.Dispose();
        }

代码
xmlhtml sh=new xmlhtml(dt,strXmlname,strHtmlname,strXSLTname,100)
dt是提供数据源的datatable，strXmlname是中间生成的xml文件的路径，strHtmlname是生成的静态html页面路径，strXSLTname是xslt样式表的路径，100是分页后每页代码显示的记录行数。
注：最后的页面尺寸参数可以不加，默认整个数据表显示到一个页面。

第二种：实例化后直接使用StaticHtml方法。最后三行为

            xmlhtml sh=new xmlhtml();
            sh.StaticHtml(dt,strXmlname,strHtmlname,strXSLTname,100);
            sh.Dispose();
