效果：

代码：

复制代码 代码如下:

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 = 0;

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");
