I have a list view code that will take the numbers from column 0 and then in order delete them. the issue im having is once i delete the first one all the numbers are different becasue when you delete 2, 3 becomes 2. I need help starting from the highest number selected in the listview to the loest. right now the following code below starts with the lowest number.

VB

Private Sub EditHeapToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles EditHeapToolStripMenuItem.Click

       Dim strObject As String = "C:\Temp\ASERVICE.EDM"

       For Each sitem As ListViewItem In Radia_Listview.SelectedItems
                      AZDelete(sitem.Text)
       Next

   End Sub

so the above code gives and output of:
12345

and i need it to start with
54321

VB

'=======================================================================================
'The below code will create an array for the items that need to be deleted from Zservice
'=======================================================================================

' Delcaring the selected items as heap_num
Dim Zheap_num = CAE_Listview.SelectedItems(0).SubItems(1).Text ' heap name
Dim ZPATH As String = "\\" & strComputer & "\C$\Progra~2\Hewlett-Packard\HPCA\Agent\Lib\SYSTEM\RADIA\SOFTSRVC\ZSERVICE\"
Dim Zlist As New ArrayList

'For each selected item add the item number to an array list
For Each sITEM In Zheap_num
    Zlist.Add(sITEM)
Next

'reverse the arraylist from 012345 to 543210
Zlist.Reverse()


For Each DelZ In Zlist
    'adds the heap name to the textbox for del_heap that will display once its finished
    'deleting the items selected
    Del_Heap.Del_TextBox.Text += DelZ.text & vbCrLf

    'if the folder exist it will delete it if it dosent exist it will keep going
    If System.IO.Directory.Exists(ZPATH & DelZ.text) Then
        Directory.Delete(ZPATH & DelZ.text, True)
    End If
