LINQ的反向的GroupBy

Question

我有這個疑問：

from e in Employee 
join t in TimeTable 
    on e.Id equals t.EmpId 
group new {e,t} by e.Id into g 
orderby g.Key 
select new 
{ 
    Emp = g.Key, 
    Items = g.Select(c => c.t.OtherTable.Somevalue).Distinct() 
} 

它工作正常，但我需要扭轉組合，這樣它會小組OtherTable.Somevalue

我該怎麼做，所有Employees？

可能喜歡以下這一點，將工作

from e in Employee 
join t in TimeTable 
    on e.Id equals t.EmpId 
group new {e,t} by t.OtherTable.Somevalue into g 
orderby g.Key 
select new 
{ 
    SomeValue = g.Key, 
    Emplyees = g.Select(c => c.e.Id).Distinct() 
}
