在列表视图C#中移动选中项的组

ListView listView = new ListView();
listView.View = View.Details; // 设置列表视图的显示方式为详细信息模式
listView.FullRowSelect = true; // 设置选中项时同时选中整行

listView.Columns.Add("列1");
listView.Columns.Add("列2");
listView.Columns.Add("列3");

ListViewItem item1 = new ListViewItem("行1数据1");
item1.SubItems.Add("行1数据2");
item1.SubItems.Add("行1数据3");

ListViewItem item2 = new ListViewItem("行2数据1");
item2.SubItems.Add("行2数据2");
item2.SubItems.Add("行2数据3");

listView.Items.Add(item1);
listView.Items.Add(item2);

if (listView.SelectedItems.Count > 0)
{
    ListViewItem selectedItem = listView.SelectedItems[0];
    int currentIndex = selectedItem.Index;

    // 向上移动选中项
    if (currentIndex > 0)
    {
        listView.Items.RemoveAt(currentIndex);
        listView.Items.Insert(currentIndex - 1, selectedItem);
        listView.Items[currentIndex - 1].Selected = true;
    }

    // 向下移动选中项
    if (currentIndex < listView.Items.Count - 1)
    {
        listView.Items.RemoveAt(currentIndex);
        listView.Items.Insert(currentIndex + 1, selectedItem);
        listView.Items[currentIndex + 1].Selected = true;
