我有一个问题:
from m in dc.ReportingMonths
where m.Month.Value == month
select (from k in m.KPI_Actives
where k.DateActive.Year == year
select (from r in dc.ReportingViews
where r.KPIID == k.KPIID select r)
);
显然,因为它是嵌套的LINQ查询 - 每个返回一个IQueryable,我得到一组IQueryables作为结果。
如何在不使用foreach循环创建新列表的情况下编写类似的查询,而只返回ReportingView的单个平面列表(如上一个查询返回)?
谢谢!

类似的东西:
from m in dc.ReportingMonths where m.Month.Value == month
from k in m.KPI_Actives
where k.DateActive.Year == year
from r in dc.ReportingViews
where r.KPIID == k.KPIID
select r;
