<ListBox PreviewDrop="ListBox_PreviewDrop">

private void ListBox_PreviewDrop(object sender, DragEventArgs e)
{
    // 获取拖放的数据
    var data = e.Data.GetData(typeof(string));

    // 获取目标项
    var listBox = sender as ListBox;
    var targetItem = GetListBoxItem(listBox, e.GetPosition(listBox));

    // 处理拖放操作
    // ...
}

private ListBoxItem GetListBoxItem(ListBox listBox, Point position)
{
    var item = VisualTreeHelper.HitTest(listBox, position).VisualHit;

    while (item != null && !(item is ListBoxItem))
    {
        item = VisualTreeHelper.GetParent(item);
    }
