我在linq中有以下查询:
(from creditCard in DbSet
join rank in base.dataContext.ProductVerticalRanks on creditCard.ProductVerticalReferenceId equals rank.ProductVerticalReferenceId
where rank.ClientId == clientId
orderby rank.PreferredOrder
select creditCard)
.Include(creditCard => creditCard.ProductVerticalCompany)
.Include(creditCard => creditCard.Labels);
但是现在我有了一个新的要求,我需要在表“ rank”中添加一个列“ rank.PreferredOrder”到结果中,是否有一种简单的方法而无需进行大量的“ select”语句,因为仅信用卡中大约有20-30个字段。
答案 0 :(得分:2)
我前面没有您的模型,因此无法确认,但是您可以使用这样的匿名对象:
from creditCard in DbSet
join rank in base.dataContext.ProductVerticalRanks on
creditCard.ProductVerticalReferenceId equals rank.ProductVerticalReferenceId into g
where rank.ClientId == clientId
orderby rank.PreferredOrder
select new {Card = creditCard, Ranks = g}
