Answer 1

There are several other classes you can select from like

• SortedDictionary
• List
• HashSet

you can review the options by looking at System.Collections.Generic Namespace.

Their is a very good post, describibg pros and cons for all most of the collection classes at MSDN

• Selecting a Collection Class

If you are not satisfied by what these classes are provide, you can go for your own collection class or design a custom Dictionary your self.

you will need to inherit your custom dictionary fron IDictionary Interface and other classes / interfaces or may write all from scratch.

Here is the signature for Dictionary class at MSDN

[SerializableAttribute]
[ComVisibleAttribute(false)]
public class Dictionary : IDictionary, 
    ICollection>,
    IEnumerable>, 
    IDictionary, ICollection, IEnumerable,
    ISerializable, IDeserializationCallback
