I have two tables
TableA
aId
aValue
TableB
bId
aId
bValue
I want to join these two tables via aId
, and from there, group them by bValue
var result =
from a in db.TableA
join b in db.TableB on a.aId equals b.aId
group b by b.bValue into x
select new {x};
My code doesn't recognize the join after the group. In other words, the grouping works, but the join doesn't (or at least I can't figure out how to access all of the data after the join).
The expression between the group
and the by
creates the group elements.
var result =
from a in db.TableA
join b in db.TableB on a.aId equals b.aId
group new {A = a, B = b} by b.bValue;
// demonstration of navigating the result
foreach(var g in result)
{
Console.WriteLine(g.Key);
foreach(var x in g)
{
Console.WriteLine(x.A.aId);
Console.WriteLine(x.B.bId);
}
}
