Use a repeat loop to add Listbox data to an array using the Copyto method.

Something like:

For i = 0 To ListBox1.Count - 1
    ListBox1.Items.CopyTo(seuarray, i)
Next
seuarray.Sort()

The very one Array.Sort of. Net Framework already brings some ease to you because behind it already implements algorithms like Quicksort and Heapsort depending on the size of the input array. In the worst case the complexity is O(n log n)

If the difficulty is just getting the array values then the Catharina solution already helps you.
