Question

Is it possible to create a list that can be access by either an index or a key?

I am looking for a Collection type that already exists but has this facility, I want to avoid redefining the indexers

Answer 1

System.Collections.Specialized.NameValueCollection can do this, but it can only store strings as values.

    System.Collections.Specialized.NameValueCollection k =          new System.Collections.Specialized.NameValueCollection();      k.Add('B', 'Brown');     k.Add('G', 'Green');      Console.WriteLine(k[0]);    // Writes Brown     Console.WriteLine(k['G']);  // Writes Green
