Simple collection for single key multiple data?

[Jon Slaughter]

Is there a collection that lets you use a "multimap" like feature.

something like

MultiHash.Add(Some_Key, Data1);
MultiHash.Add(Some_Key, Data2);
....


Obviously I could handle this with an ArrayList in a HashTable but for my
purposes it would be much easier if I had the above functionality(probably
would be to hard to add it or extend the hashtable if thats possible but
wondering if theres something already built in.

Thanks,
Jon

Jon,

DataTable by some seen as something very strange but just a class which with
its DataView(defaultview property) is implementing the ILIST and the
ICollection.
