        /// </summary>
        public int totalRows { get; set; }
        #endregion

        #region 构造函数
        public PagerModel()
        {

        }
        /// <summary>

        {
            this.page = page;
            this.rows = rows;

        #endregion

        #region 扩展字段
        /// <summary>

        public int pageCount
        {
            get
            {
                if (rows != )
                {

                else

                }
            }
        }
        /// <summary>
        /// 上一页
        /// </summary>
        public int prePage

                {
                    return page + ;
                }
                return pageCount;
            }
        }
        #endregion

    }
}

如何使用：

PagerModel pager = pagerControl.Pager;
List<BS_Meeting_ext> list;
if (cbxReviewTime.Checked)
{
    list = m_MeetingDal.GetList(ref pager, cbxType.SelectedValue.ToString(), txtTerm.Text, txtNum.Text, dtpStart.Value.ToString("yyyy-MM-dd"), dtpEnd.Value.ToString("yyyy-MM-dd"));
}
else
{
    list = m_MeetingDal.GetList(ref pager, cbxType.SelectedValue.ToString(), txtTerm.Text, txtNum.Text, null, null);
}
pagerControl.Pager = pager;
