I didn't try it. But maybe you can use the CopyTo() method of the hashtable to copy it into an array. When having the array you can sort the data.

because i used a Hashtable and inserted objects but the order on what location the objects are in the array is not the way how i inserted them. That's why it uses the key to retrieve the value from the hashtable :) Why is the order of inserted objects important?

Well ArrayList is FiLo for instance And no key is needed. The objects are aligned in the order you entered them.
