Dapper的分页代码

        public KeyValuePair<Pagination, IList<AttachmentModel>> AttachmentPagination(Pagination pagin, AttachmentModel condition)
        {
            using (SqlConnection conn = DapperFactory.CrateOpenConnection())

                String executeQuery = @"WITH pagintable AS(

                                        SELECT * FROM pagintable where RowID between ((@CurrentPageIndex - 1)  * @PageSize) + 1  and (@CurrentPageIndex  * @PageSize)";
                String executeCount = "SELECT COUNT(*) AS CountNum FROM Attachment WHERE 1= 1";
                var mixCondition = new
