C#: how to get a custom hashtable so that it can be xml serialized

[PRR]

how and why isnt it already provided??lol.... i wanted to inherit class hashtable and add a new field so that i can associate value and my new field to the KEY... i can inherit hashtable ..override ADD.. but how do i associate the key with my own field... Dont tell to have 2 hashtables.... i already tried that... but i guess it may be possible to do iwth 1... one more very impt thing... how do i get custom hashtable to be xml serialized?

public class my: hashtable
{
public list<int> myfield;
public override add(three objects)
base.add(2 object passed here)

/// now here how do i get myfield to get associated with KEY?
}

A DataTable would hold any number of objects with any number of relations? It also comes with XML stuff. Would that work?

System.Collection.Specialized contains Dictionary/HashTable stuff too.
