如何在Linq中编写SELECT FROM myTable WHERE id IN(SELECT ...)？

Question

你如何在Linq中重写这个？

SELECT Id, Name FROM TableA WHERE TableA.Id IN (SELECT xx from TableB INNER JOIN Table C....)

所以用简单的英语,我想从TableA中选择Id和Name,其中TableA的Id在第二个查询的结果集中.

Answer 1

from a in TableA 
where (from b in TableB 
       join c in TableC on b.id equals c.id
       where .. select b.id)
.Contains(a.Id) 
select new { a.Id, a.Name }
