Dictionaries are unordered. If you mean “the 5th item added to the dictionary” – they don’t provide this functionality.
One thing to be careful of is that in many cases
Dictionary<TKey, TValue>appears to be ordered – if you just add a bunch of entries and then iterate, then under the current implementation I believe you will at least usually get back the pairs in the same order. However, it’s not guaranteed, it’s not meant to happen particularly – it’s just a quirk of the implementation. If you delete entries and then add more, then the whole thing goes pear-shaped.Fundamentally, if you want ordering as well as key lookups, you need to store a list as well as a dictionary.
