Linq subquery from observablecollection.

Question

I have an ObservableCollection which contains types of the following
class Customer
{
  public string Name;
  public bool IsSelected;
  public ObservableCollection<InnerType> items;
}

class InnerType
{
  public string ItemName;
  public bool bought;
}

Now i want to create a Dictionary<string,List<string> using a Linq query.. where the key in the dictionary would be "Name" from Customer type  where IsSelected == true and the Values (List<string>) would be all "ItemName" entries in "items" where bought == true. Can i achieve this with one query?
Thanks in advance.. 

Answer 1

How about this:

list.Where(c => c.IsSelected)
    .Select(c => new
    {
        Name = c.Name,
        ItemNames = c.items.Where(i => i.bought).Select(i => i.ItemName).ToList()
    })
    .ToDictionary(c => c.Name, c => c.ItemNames);

Document my code? Why do you think it's called "code"?
