将此 sql 命令转换为 C# linq

Question

我正在尝试将此 tSql 命令转换为 linq 查询。
我想对这些列进行分组。
你能帮帮我吗？

select  vUnit.FK_Unit_ID , Unit.unitNumber, unit.unitTitle , title.featureTitleName
from unit.UnitFeatureValue vUnit
inner join unit.Unit on vUnit.FK_Unit_ID = Unit.ID
inner join unit.FeatureTitle title on vUnit.FK_FeatureTitle_ID = title.ID
where vUnit.FK_Unit_ID = 15 and title.canMoreSelect = 1
group by vUnit.FK_Unit_ID ,unit.unitNumber, unit.unitTitle , title.featureTitleName

Answer 1

像这样

var result = (from v in vUnit 
join u in unit on v.FK_Unit_ID equals u.ID
join t in title on v.FK_FeatureTitle_ID equals t.ID
where v.FK_Unit_ID == 15 and t.canMoreSelect == 1
select new { v.FK_Unit_ID , u.unitNumber, u.unitTitle , t.featureTitleName }).ToList();

Answer 2

var query = (
    from v in dbContext.UnitFeatureValue
    join u in dbContext.Unit on v.FK_Unit_ID equals u.ID
    join t in dbContext.FeatureTitle on v.FK_FeatureTitle_ID equals t.ID
    where v.FK_Unit_ID == 15 && t.canMoreSelect == 1
    select  new {
        v.FK_Unit_ID, 
        u.unitNumber, 
        u.unitTitle, 
        t.featureTitleName,
    }).Distinct();
