Sub Select into LINQ

Question

I am rather new to LINQ and I wrote a query in SQL that I am not quite sure how to convert to a LINQ statement. What I have causes a syntax error on the MAX(), probably because MAX() cannot operate on a datetime value

Any help is appreciated.

SQL

select COUNT(distinct Club) as total
FROM GCClubData 
where NCBClub = 0 
and Date = (select max(Date) from GCClubData)

LINQ

var db = new EFContext();
var data = db.GCClubDatas.Where(x => x.Date.Equals(db.GCClubDatas.Max().Date) && !x.NCBClub);

Answer 1

db = new EFContext();
var maxDate = db.GCClubDatas.Max(x => x.Date);
var data = db.GCClubDatas.Where(x => x.Date == maxDate && !x.NCBClub);

Answer 2

就数据库命中而言，这将更加有效：

db.GCClubDatas.Where(x => x.Date == db.GCClubDatas.Max(y => y.Date) && x.NCBClub == 0);
