点滴积累【C#】---操作xml,将xml数据显示到treeview

效果：

代码：

 XmlDocument xml = new XmlDocument();
         private void Form1_Load(object sender, EventArgs e)
         {
             CreateXML();
             TreeNode tn = new TreeNode("魔兽");
             treeView1.Nodes.Add(tn);
             xml.Load(@"D:\XMLFile.xml");
             XmlNode nod = xml.DocumentElement;
             int i = ;
             foreach (XmlNode xn in nod.ChildNodes)
             {
                 treeView1.TopNode.Nodes.Add(xn.Attributes["two"].Value);

                 foreach (XmlNode xn2 in xn.ChildNodes)
                 {
                     treeView1.TopNode.Nodes[i].Nodes.Add(xn2.InnerText);
                 }
                 i++;
             }
         }
         public void CreateXML()
         {
             //创建xml文件
             XmlDeclaration dec = xml.CreateXmlDeclaration("1.0", "utf-8", null);
             xml.AppendChild(dec);
             //添加树形字段
             XmlElement one = xml.CreateElement("one");
             XmlElement two = xml.CreateElement("two");
             XmlElement two1 = xml.CreateElement("two");
             XmlElement three = xml.CreateElement("three");
             XmlElement threeDL = xml.CreateElement("three");
             XmlElement three1 = xml.CreateElement("three");
             XmlElement three10 = xml.CreateElement("three");
             //添加树形结构关系
             xml.AppendChild(one);
             one.AppendChild(two);
             one.AppendChild(two1);
             two.AppendChild(three);
             two.AppendChild(threeDL);
             two1.AppendChild(three1);
             two1.AppendChild(three10);
             //添加属性
             two.SetAttribute("two", "不死");
             two1.SetAttribute("two", "暗夜");
             //添加内容
             three.InnerText = "DK";
             threeDL.InnerText = "DL";
             three1.InnerText = "DH";
             three10.InnerText = "WD";
             xml.Save(@"D:\XMLFile.xml");
         }
