ListBox SelectionMode can be set single or multiple, in both cases below code will work

int[] selection = MenuBox.GetSelectedIndices();
while (selection.Length >0)
{
    UpdatedBox.Items.Add(MenuBox.Items[selection[0]].ToString());
    MenuBox.Items.RemoveAt(selection[0]);
    selection = MenuBox.GetSelectedIndices();
}

Answer 3

ListBox2.Items.Add(ListBox1.SelectedItem);

Try this

 while(ListBox1.Items.Count!=0)
 {
    for(int i=0;i<ListBox1.Items.Count;i++)
    {
        ListBox2.Items.Add(ListBox1.Items[i]);
        ListBox1.Items.Remove(ListBox1.Items[i]);
    }
 }
