点滴积累【C#】---操作xml,将xml数据显示到treeview

效果：

代码：

 1 XmlDocument xml = new XmlDocument();

 2         private void Form1_Load(object sender, EventArgs e)

 3         {

 4             CreateXML();

 5             TreeNode tn = new TreeNode("魔兽");

 6             treeView1.Nodes.Add(tn);

 7             xml.Load(@"D:\XMLFile.xml");

 8             XmlNode nod = xml.DocumentElement;

 9             int i = 0;

10             foreach (XmlNode xn in nod.ChildNodes)

11             {

12                 treeView1.TopNode.Nodes.Add(xn.Attributes["two"].Value);

13 

14                 foreach (XmlNode xn2 in xn.ChildNodes)

15                 {

16                     treeView1.TopNode.Nodes[i].Nodes.Add(xn2.InnerText);

17                 }

18                 i++;

19             }

20         }

21         public void CreateXML()

22         {

23             //创建xml文件

24             XmlDeclaration dec = xml.CreateXmlDeclaration("1.0", "utf-8", null);

25             xml.AppendChild(dec);

26             //添加树形字段

27             XmlElement one = xml.CreateElement("one");

28             XmlElement two = xml.CreateElement("two");

29             XmlElement two1 = xml.CreateElement("two");

30             XmlElement three = xml.CreateElement("three");

31             XmlElement threeDL = xml.CreateElement("three");

32             XmlElement three1 = xml.CreateElement("three");

33             XmlElement three10 = xml.CreateElement("three");

34             //添加树形结构关系

35             xml.AppendChild(one);

36             one.AppendChild(two);

37             one.AppendChild(two1);

38             two.AppendChild(three);

39             two.AppendChild(threeDL);

40             two1.AppendChild(three1);

41             two1.AppendChild(three10);

42             //添加属性

43             two.SetAttribute("two", "不死");

44             two1.SetAttribute("two", "暗夜");

45             //添加内容

46             three.InnerText = "DK";

47             threeDL.InnerText = "DL";

48             three1.InnerText = "DH";

49             three10.InnerText = "WD";

50             xml.Save(@"D:\XMLFile.xml");

51         }
