Is the order of elements on a C# List deterministic?

Question

I\'ve always thought otherwise, but recently I had the need to know:

If I add elements to a list in a certain order, am I guaranteed to find then always on the same

Answer 1

Yes; you control the ordering of a List.

You can assume that any .NET collection with a list[int] indexer has a predictable ordering; otherwise, the numerical index wouldn't make any sense. By comparison, it's not possible to use a numerical index with a Dictionary, and when you enumerate a dictionary, the ordering isn't guaranteed.
