我所常用的分页

如下：

        public List<Product> GetSavedProductsByUserId(int userId, int pageNumber, int pageSize)
        {
            var sql = @"
WITH tempGR AS
(                                         
    SELECT ROW_NUMBER() over( order by a.Id desc) as ReqIndex ,COUNT(a.Id) OVER() as ReqCount ,
    B.*, C.*
    FROM dbo.StoredProducts A
    LEFT JOIN Product B ON A.ProductId=B.Id
    LEFT JOIN ProductBase C ON B.BaseId=C.PBaseId
    WHERE A.UserId=@userId
)
SELECT * FROM TEMPGR WHERE ReqIndex BETWEEN @StartIndex and @EndIndex
";
            var pms = new SqlParameter[] {
                new SqlParameter("@UserId",userId),
                new SqlParameter("@StartIndex",(pageNumber - 1) * pageSize + 1),
                new SqlParameter("@EndIndex", pageNumber * pageSize)
            };
            var x = SqlHelper.ExecuteDataset(CommandType.Text, sql, pms);
            var re = DataTableHelper.ToList3<Product>(x.Tables[0]);
            return re;
        }
