实体框架T-Sql"具有"等价物

如何将linq写入包含having子句的实体查询？

例如:

SELECT State.Name, Count(*) FROM State
INNER JOIN StateOwner ON State.StateID = StateOwner.StateID
GROUP BY State.StateID
HAVING Count(*) > 1

有什么理由不在where结果上使用条款？

var query = from state in states
            join stateowner in stateowners
              on state.stateid equals stateowner.stateid
            group state.Name by state.stateid into grouped
            where grouped.Count() > 1
            select new { Name = grouped.Key, grouped.Count() };
