Global entity: { WorkerId , ProjId, Date }
Worker entity: { Workerid, WorkerName }
Project entity: { ProjId, ProjName }
New Projects entity : { ProjId, ProjInf }
的的WebMethod需要收到的日期,并返回:LINQ专业查询的WebMethod
>WorkerName
>how many projects he has // count Project entity with WorkerId
>how many new projects he has // count New Projects entity with ProjId, we know wich ProjId needs to be count for the worker from the Global entity
请帮我建立这个LINQ查询......我不能发现所有对谷歌的任何解决方案
