SELECT BH,GroupID , COUNT(*) AS Expr1
FROM CataLogDetail
where ((GroupID = 1) AND (Company =66))
AND ((LB = '身份') AND (LM IN ('合同工'))

------解决方案--------------------

C# code

var query=from c in db.CataLogDetail          where (c.GroupID==1 && c.Comany==66)          &&(c.LB=="身份" && new string[]{"合同工"}.Contains(c.LM))          || (c.LB=="学历" && new string[]{"本科"}.Contains(c.LM))          group c by new {c.bh,c.GroupID} into g          where  g.Count()==2          select new           {                g.Key.bh,              g.Key.GroupID,              Expr1=g.Count()          };          //代码手打，提供思路参考
