I am sorry, I should have said also that I am using SandstoneDb to try to save these objects. A SortedCollection is the type of collection I need, but SandstoneDb cannot save it.
Sometimes an image is worth a thousand words. So this image I made may help you.
Also, as Mariano points out, remember that you can convert from one collection to another by sending the message #asCollectionName replacing the CollectionName for the collection you want.
So for example to remove all duplicates from a collection, asSet is a simple and pretty way to do it.Cheers--�
