linq groupby

[Carel]

Hi all,

If I have set of fields of which I use some for grouping and some for aggregating, how can I have other fields in the final step where the aggregating also takes place?

Suppose there is also a t.c and a t.d in the input sequence that I want in the select new part, how to do that?

var output = 
from t in input
group t
by new 
{
	w = t.a,
	x = t.b
}
into s
select new 
{
	w = s.Key.w,
	x = s.Key.x,
	a = s.Average(u => u.q)
};
