如何在C＃中的ListView中单击鼠标来填充TreeView节点

Question

我的C＃项目（WinApplication）存在问题。我无法将所选节点从treeview填充到listview。我怎么能这样做呢; 这就是我到目前为止所做的：

 List<TreeNode>checked_tree_nodes=new List<TreeNode>();

private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
    {
        if (e.Action != TreeViewAction.Unknown)
        {
            if (e.Node.Nodes.Count > 0)
            {
                unchecknodes(e.Node, e.Node.Checked);
            }
        }
        if (e.Action != TreeViewAction.Unknown)
       {
            if (e.Node.Nodes.Count > 0)
            {
                checknodes(e.Node, e.Node.Checked);
            }
        }
        foreach (TreeNode trl in checked_tree_nodes)
        {
            string text = "";
            ListViewItem lv = listView1.FindItemWithText(text);
            ListViewItem lvi = new ListViewItem(ypoxrewseis[treeView1.SelectedNode.Index].name);
            lvi.SubItems.Add(task[treeView1.SelectedNode.Index].type);                     lvi.SubItems.Add(task[treeView1.SelectedNode.Index].date.ToString());

            if (lv == null)
            {
                listView1.Items.Add(lvi);
            }
            else
            {
                MessageBox.Show("Exists!");
            }
        }
    }

提前致谢！
