TreeList<T>?

[Shadowblitz16]

I just installed C5 2.5.3 and there doesn't seem to be a TreeList type.

I need a ordered, reorderable, generic tree collection that allows duplicates

What is the usage scenario?

Would a MultiDictionary be sufficient, see the C5 handbook section 11.12, eg here: https://www.itu.dk/research/c5/latest/ITU-TR-2006-76.pdf

I wanted to use it for a entity component system. I need the items to be reorderable and allow multiple instances of the same object

So the items are not ordered by a comparer?

no by a index

Would a HashedLinkedList where the hashing is on that index serve this purpose? Constant-time access to items by index, reorderable, duplicate objects (but not indices) allowed, sequential traversal, insertion etc

Is a HashedLinkedList a tree collection? a simple list won't do
