分部类 添加字段操作

//查询所有的经理
var areaJingLi = dataContext.TblLoginInfo.Where(item => item.intRoleId == 3);

//将经理和主管按照区域进行合并
var resultList = from zhuguan in areaZhuGuan
from jingli in areaJingLi

where jingli.TblAreaInfo.chvAreaName.Contains(AreaName)

//因为主管和经理在where条件中已经进行合并处理：即：zhuguan和jingli是同一地区的，所以在查询区域信息的时候使用主管或经理都是一样的结果

//获取数据数量

//Skip 制定列表中的元素，返回剩余的元素
