代码生成器大数据分页

 

下面参考代码是简易的数据权限的实现,大多情况下下面的数据权限的功能可以满足很多企业的需要了

        #region public DataTable GetDataTableByPage(BaseUserInfo userInfo, out int recordCount, int pageIndex = 0, int pageSize = 20, string sortExpression = null, string sortDire = null) 分页查询
        /// <summary>
        /// 分页查询
        /// </summary>
        /// <param name="userInfo">用户</param>
        /// <param name="recordCount">记录数</param>
        /// <param name="pageIndex">当前页</param>
        /// <param name="pageSize">每页显示记录条数</param>
        /// <param name="sortExpression">排序字段</param>
        /// <param name="sortDire">排序方向</param>
        /// <returns>数据表</returns>
