Change ListBoxN.Items to ArrayList

hi ddanbe...Thanks

i Know..... Change ListBoxN.Items to ArrayList

but how to do this in arraylist??

R = ListBox1.Items.Count - 1
ListBox1.SelectedIndex = Rnd() * R
ListBox2.Items.Add(ListBox1.SelectedItem.ToString)

how to make rundom select index in array ??????

If you help me, I appreciate you

Dim rnd As New Random()

R = ListBox1.Items.Count - 1 ---> R = ArraList1.Count
ListBox1.SelectedIndex = Rnd() * R ---> int SelectedIndex =rnd.Next(0,R)
ListBox2.Items.Add(ListBox1.SelectedItem.ToString) ---> ArrayList2.Add(ArrayList1.Item(SelectedIndex)

Maby some type errors here but I hope you get the general idea. Succes.
