比较简单，用到三个控件button treeview openFileDialog 上代码，关键技术：递归
form
1 using System;
2 using System.Collections.Generic;
3 using System.ComponentModel;
4 using System.Data;
5 using System.Drawing;
6 using System.Linq;
7 using System.Text;
8 using System.Windows.Forms;
9 using System.Xml;
10
11
12 namespace WindowsFormsApplication4
13 {
14 public partial class Form1 : Form
15 {
16 public Form1()
17 {
18 InitializeComponent();
19 }
20
21 private void button1_Click(object sender, EventArgs e)
22 {
23 //从XML中读取数据到TreeView
24 if (this.openFileDialog1.ShowDialog() == DialogResult.OK)
25 {
26 XmlDocument xmlDoc = new XmlDocument();
27 xmlDoc.Load(openFileDialog1.FileName);
28
29 XmlNodeList xmlNodes = xmlDoc.DocumentElement.ChildNodes;
30
31 this.treeView1.BeginUpdate();
32 this.treeView1.Nodes.Clear();
33 XmlNode2TreeNode(xmlNodes, this.treeView1.Nodes);
34 this.treeView1.EndUpdate();
35 }
36 }
37
38
39 private void XmlNode2TreeNode(XmlNodeList xmlNode, TreeNodeCollection treeNode)
40 {
41 foreach (XmlNode var in xmlNode)
42 {
43 if (var.NodeType != XmlNodeType.Element)
44 {
45 continue;
46 }
47 TreeNode newTreeNode = new TreeNode();
48 if (var.Attributes.Count == 2)
49 {
50 newTreeNode.Text = var.Attributes[0].Name + "=" + var.Attributes[0].Value
51 + " " + var.Attributes[1].Name + "=" + var.Attributes[1].Value;
52 }
53 else
54 {
55 newTreeNode.Text = var.Attributes[0].Name + "=" + var.Attributes[0].Value
56 + " " + var.Attributes[1].Name + "=" + var.Attributes[1].Value
57 + " " + var.Attributes[2].Name + "=" + var.Attributes[2].Value;
58 }
59
60
61 if (var.HasChildNodes)
62 {
63 if (var.ChildNodes[0].NodeType == XmlNodeType.CDATA)
64 {
65 newTreeNode.Tag = var.ChildNodes[0].Value;
66 }
67
68 XmlNode2TreeNode(var.ChildNodes, newTreeNode.Nodes);
69 }
70 treeNode.Add(newTreeNode);
71 }
72 }
73 }
74 }
