TreeView 转XML 怎么操作？

前两天刚做的代码赋值给你
//XML每行的内容
        private string xmlLine = "";
        //用于写XML文件
        private StreamWriter sr;        private void Form1_Load(object sender, EventArgs e)
        {
            TreeNode tb = new TreeNode();
            tb.Text = "父节点";
            TreeNode tn = new TreeNode();
            tn.Text = "ceshi";
            TreeNode ts = new TreeNode();
            ts.Text = "tree";
            tn.Nodes.Add(ts);
            tb.Nodes.Add(tn);
            tn = new TreeNode();
            tn.Text = "完全";
            tb.Nodes.Add(tn);
            treeView1.Nodes.Add(tb);
        }        private void button1_Click(object sender, EventArgs e)
        {
            //XmlDocument doc = new XmlDocument();
            //XmlElement Node1 = doc.CreateElement("charts");//创建节点anychart子节点charts
            //doc.AppendChild(Node1);
            //XmlElement Node4 = doc.CreateElement("chart_settings");//创建节点chart第二个子节点chart_settings
            //doc.DocumentElement.AppendChild(Node4);
            //doc.Save("c:\\text.xml"); //保存xml               exportToXml(this.treeView1, "C:\\text.xml");        }
        /// <summary>
        /// 将TreeView中导出为XML数据
        /// </summary>
        /// <param name="tv">TreeView控件</param>
        /// <param name="filename">XML文件的保存路径</param>
        public void exportToXml(TreeView tv, string filename)
        {
            sr = new StreamWriter(filename, false, System.Text.Encoding.UTF8);
            //写文件头部内容
            //下面是生成RSS的OPML文件
            sr.WriteLine("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
            sr.WriteLine("<opml version=\"1.0\">");
            sr.WriteLine("<head>");
            sr.WriteLine("<title>RSS</title>");
            sr.WriteLine("</head>");
            sr.WriteLine("<body>");            //遍历根节点
            foreach (TreeNode node in tv.Nodes)
            {
                if (node.Nodes.Count == 0)
                {
                    xmlLine = GetRSSText(node);
                }
                else
                {
                    xmlLine = GetDirectoryText(node);
                }                sr.WriteLine(xmlLine);                //递归遍历节点
                parseNode(node);
            }            //写文件尾部内容
            sr.WriteLine("</body>");
            sr.WriteLine("</opml>");
            sr.Close();
        }        //递归遍历节点内容,最关键的函数
        private void parseNode(TreeNode tn)
        {
            IEnumerator ie = tn.Nodes.GetEnumerator();            while (ie.MoveNext())
            {
                TreeNode ctn = (TreeNode)ie.Current;                //为最底层节点,即该节点为RSS节点
                if (ctn.Nodes.Count == 0)
                {
                    xmlLine = GetRSSText(ctn);
                    sr.WriteLine(xmlLine);
                }
                else//不是最底层节点,即该节点为目录节点
                {
                    xmlLine = GetDirectoryText(ctn);
                    sr.WriteLine(xmlLine);
                }                //如果还有子节点则继续遍历
                if (ctn.Nodes.Count > 0)
                {
                    parseNode(ctn);
                }
            }            sr.WriteLine("</outline>");
        }        //成生RSS节点的XML文本行
        private string GetRSSText(TreeNode node)
        {
            //根据Node属性生成XML文本
            string rssText = "<outline type=\"rss\" text=\"" + node.Text + "\" xmlUrl=\"URL\"/>";            return rssText;
        }        //成生目录节点的XML文本行
        private string GetDirectoryText(TreeNode node)
        {
            //根据Node属性生成XML文本
            string directoryText = "<outline text=\"" + node.Text + "\">";            return directoryText;
        }

用文件流
读取节点写入XML中。平时怎么从XML中获得数据就怎么把数据送回去

private void TreeNode2Xml(TreeNodeCollection treeNodes, XmlNode xmlNode)
        {
            XmlDocument doc = xmlNode.OwnerDocument;
            foreach (TreeNode treeNode in treeNodes)
            {
                XmlNode element = doc.CreateNode("element", "Item", "");
                XmlAttribute attr = doc.CreateAttribute("Title");
                attr.Value = treeNode.Text;
                element.Attributes.Append(attr);
                element.AppendChild(doc.CreateCDataSection(treeNode.Tag.ToString()));
                xmlNode.AppendChild(element);                if (treeNode.Nodes.Count > 0)
                {
                    TreeNode2Xml(treeNode.Nodes, element);
                }
            }
        }
