Please help when removing multiple selectedindices integers

Quote:

Okay, I'm Adding Items To Two ListBoxes During A Function, One For The Normal Plain Text, & Another For The MD5 Hash.

PasswordList.Items.Add(Password.Text)
MD5ListBox.Items.Add(MD5.Text)

Everything Is Proceeding Successfully, Both The Plain Text & MD5 Hashes Are Adding To ListBoxes Perfectly, But When Removing The Same Indices Which I'm Removing In The Password List, I Want To Remove In The MD5 List Too. It's Functionally Completely When I Remove One Seleceted Item, But When I Remove More Than One Seleceted Item In The Password List I Get An Error When Removing From The MD5List. I'm Basically Getting The Selected Indices In The Password List, & Using A Loop To Remove The Same Indices Integers Selected In Password List, To Remove In MD5 List.

 If PasswordList.SelectedItems.Count = 1 Then

     Dim KeyNumber As Integer = PasswordList.SelectedIndices(0)

     MD5ListBox.Items.RemoveAt(KeyNumber)

     PasswordList.Items.Remove(PasswordList.SelectedItem)

 Elseif PasswordList.SelectedItems.Count > 1

     Dim KeyNumber5 = rdpForm.PasswordList.SelectedIndices

     For Each indx5 As Integer In KeyNumber5

         rdpForm.MD5ListBox.Items.RemoveAt(indx5)

     Next

     Dim selectedItems = (From I In rdpForm.PasswordList.SelectedItems).ToList

     For Each selectedItem In selectedItems

         rdpForm.PasswordList.Items.Remove(selectedItem)

     Next

End If

There's Always An Error When Removing Indices In The MD5List, But Here's An Example.

ERROR: System.ArgumentOutOfRangeException: 'InvalidArgument=Value of '21' is not valid for 'index'. Parameter name: index' Items In ListBoxes(40), Attempting To Remove Indices(2-39)
