使用 LINQ EF 进行复杂联接
如何使用 LINQ to EF 连接两个查询？我需要返回给我的结果集，其中包括来自两个组合查询的连接数据。
1
select StockNo, Description
from VehicleOption_New
where StockNo in
(
select v.StockNo
from Vehicles v
join StatusDescription s
on v.Status = s.StatusId
where NewOrUsed = 'n' and v.model = 'cts'
)
and color is not null
2
select v.StockNo, s.StatusDescriptionText
from Vehicles v
join StatusDescription s
on v.Status = s.StatusId
where NewOrUsed = 'n' and v.model = 'cts'
How can I join the two queries using LINQ to EF? I need the result set returned to me that includes joined data from the 2 queries combined.

一旦有了等效的 EF 查询，您就可以使用
Concat()或Union()来合并结果。Once you have the equivalent EF queries you can use either
Concat()orUnion()to combine the results.
