Get key by idex from a ordered dictionary

How can I retrieve the key by using the index?

I can retrieve the value by index like: oOrderedDictionary[0].toString()

Is there something similair for a key value?
(I believe a sortedlist has a GetKey() method, but the ordered dictionary does not?)

Have you tried using the TryGetValue method?

I am using ASP.net 2.0 and intellisense does not say OrderDictionary has a TryGetValue method

Is there a reason you are using System.Collections.Specialized.OrderedDictionary instead of System.Collections.Generic.Dictionary<TKey,TValue>

from what i undestand an ordered dictionary the sort order is ordered by the order in which you addes key-value pairs. Does the generic.dictionary do the same?

I just took a quick look at the Generic.Dictionary .

I believe the TryGetValue needs you to enter a key and will return a value based on that key. What I need is to enter a index and get the key.

jonorossi

If you require that the dictionary be sorted then you should use the generic SortedDictionary:

System.Collections.Generic.SortedDictionary<TKey, TValue>

I see what you are after now. I can't seem to find what you are after in any of the collections built into .NET. For some reason none of them allow you to get the key by an index.
