Silverlight和linq / ria选择如何，执行以下操作

Question

query_TMEditSheet = _
                    From tm In Context_DomainService1TMTM.GetTMTMSQuery()
                    From ts In Context_DomainService1TMTM.GetGECODsQuery()
                    Where tm.tmsDate = MainPage.TimeSheetDateSelect_selectdate.Date
                    Where tm.tmsUserID = ts.codType

  

在此上下文中无法访问定义方法

想要选择其用户名存在于codType（gecod表格）中的tmtms记录

请指导

Answer 1

我认为你想做的是：

from tm in Context_DomainService1TMTM.GetTMTMSQuery()
join ts in Context_DomainService1TMTM.GetGECODsQuery() on tm.tmsUserID equals ts.codType
where tm.tmsDate = MainPage.TimeSheetDateSelect_selectdate.Date
