分页中的页数问题

public static int GetCountByTableName(string tableName)
        {
            return shuju_Access.GetCount(string.Format("select Count(*) from {0} datatable", tableName));
        }

                }
                else

                }
                cmd.Parameters.Clear();
                return num;

=========1、是需要注意的是关于得到总条数的时候需要用到的是：count（*）

=========2、是计算页数的是否，需要的是看什么是否加1.
