关于listview的item取得

关于listview的item获得
有一个listview，里面加载了5个图片的项，现在想用mouseenter或是mousehover事件来获得鼠标所在图片item的index，这里该如何写？FocusedItem和SelectItem貌似都不行，因为他们要先单击图片item？求教
------解决思路----------------------

private void listView1_ItemMouseHover(object sender, EventArgs e)
        {
            Point P = listView1.PointToClient(Control.MousePosition);
            ListViewItem item = listView1.GetItemAt(P.X, P.Y);
            if (item != null)
                System.Console.WriteLine("{0}", item.Index);
        }

        private void listView1_MouseEnter(object sender, EventArgs e)
        {
            listView1.ItemMouseHover +=new ListViewItemMouseHoverEventHandler(listView1_ItemMouseHover);
        }

        private void listView1_MouseLeave(object sender, EventArgs e)
        {
            listView1.ItemMouseHover -= new ListViewItemMouseHoverEventHandler(listView1_ItemMouseHover);
        }
