如何在实体框架中使用“In”SQL关键字？

这是我的 SQL 命令

SELECT KEY,NAME
from  COMPANY c 
WHERE     KEY IN (select KEY from USER_COMPANY  where UserId = @UserId)
order by NAME asc

所以我想将其转换为实体框架。

我尝试这样

 var userCompany = (from u in db.USER_COMPANY
                         where u.UserId == UserId 
                         select(u.KEY));

            var user = (from c in db.COMPANY
                        where (c => userCompany.Contains(c.KEY)
                        select c);

但它不起作用。

如何使用SQLIN实体框架中的关键字？

尝试这个：

var query = from c in db.COMPANY
            where (from u in db.USER_COMPANY
                   where u.UserId == UserId
                   select u.KEY).Contains(c.KEY)
            orderby c.NAME
            select c.KEY, c.NAME;
