Lint to Sql 查询包含对不同数据上下文上所定义项的引用
        static CapacityUnitDataContext db = new CapacityUnitDataContext(con);
        CommandDAL<B_Area> dal = new CommandDAL<B_Area>(db);

        static RainStationDataContext rdb = new RainStationDataContext(con);
        CommandDAL<B_RainStation> Rdal = new CommandDAL<B_RainStation>(rdb);

        public List<RainStation> getRain(int AreaId)

                        join area in db.B_Area on rain.ADID equals area.ID
                        select new RainStation
                        {
                            Id = rain.RainID,

            return query.ToList();
        }
[解决办法]
使用 DataContext.GetTable()方法

[解决办法]
应该需要强类型化datacontext
如：

class sets:DataContext
    {
        public sets(string str)
            : base(str)
        { }
        public string ss = "ddddd";
        public Table<Customers> customers;
    }
