Use linq to group by array element -


i have data in following structure need group id , date. date field on array. need sum amounts each date grouped id @ top level, possible linq? 

id  number  myarray[]

myarray follows:

[amount, date]

trying use this, wont work because second grouping on array on main item

input:

id number  myarray 1    5     [{500.00,2001-03-08}, {200,2001-04-04}, {600, 2001-03-09}]  2    6     [{700.00,2001-03-08}, {300,2001-03-08}] 1    7     [{400.00,2001-03-08}, {100, 2001-04-04}, {550.00,2001-12-12}]

expected result:

  id    myarray    1    [{500.00+400.00,2001-03-08}, {200+100,2001-04-04}, {600, 2001-03-09}, {550.00,2001-12-12}]     2    [{700.00,2001-03-08}, {300,2001-03-08}]  s in db.schedules  group s new {s.empid, s.weekending} g  select new { g.key.empid, g.key.weekending, g.sum(s => s.hours) }; 

var results = db.schedules.groupby(x => x.id)                           .select(g => new                                        {                                            .id = g.key,                                            .data = g.selectmany(x => x.myarray)                                                     .groupby(x => x.date)                                                     .select(g2 => new { amount = g2.sum(x => x.amount), date = g2.key })                                                     .toarray()                                         });
