Instead of having array2 i would make a List. A List is basically an array but you can add and remove elements/indecies dynamically.

First declare your new list

Dim array2 as new List (of ItemQty)

Then you would need to iterate over each item in the original array

For Each Item as ItemQty in array1

End For

Inside that loop You need to decide if the current Rate has been calculated yet. You would do that by checking it against the array2 list. Once you have decided that the current Rate has not been calculated all you need to do is reiterate over the original array and sum up the Qty.

You can use a Dictionary with rate as key and qty as value.
Dictionary(TKey, TValue) Class (System.Collections.Generic)
