SQLページング、行レコードの検索、C#ASP.NETページング方法

SQL文:

select * from
(select ROW_NUMBER() over(order by @    ) as rowNum,      from Expend where   ) as tab where 
rowNum>=@   and rowNum<=@  

C#コード:

         /// <summary>
        ///       
         /// </summary>

        /// <param name="whereSQL">    (  where   )</param>
        /// <param name="orderSQL">    (  ，  )</param>
        /// <param name="start">     ( 0  ，    start    )</param>
        /// <param name="limit">     </param>
        /// <returns></returns>
