Invoice headers:

class Doc {
public int Dokumnr {get; set;}
}

Invoice rows:

class Row {
public int Dokumnr {get; set;}
public int Product {get; set;}
}

I need to get list of invoices which contain product 123.
In Sql I can write

SELECT *
FROM Doc
WHERE Dokumnr in (SELECT Dokumnr FROM Row WHERE Produce=123);

How to convert this to DLinq (Linq To Sql) ?

Something like:

var q = from d in alldocs
where (from r in allrows where r.Product==123 select
r.Dokumnr).Contains(d.Dokumnr)
select d;
