C#读取XML配置文件

DataSource.xml文件，要放在bin/debug/目录下：

 <?xml version="1.0" encoding="utf-8" ?>
 <DataSource>
   <type>
     <ID>001</ID>
     <name>张三</name>
   </type>
   <type>
     <ID>002</ID>
     <name>李四</name>
   </type>
   <type>
     <ID>003</ID>
     <name>王五</name>
   </type>
 </DataSource>

CS代码：

 using System;
 using System.Collections.Generic;
 using System.ComponentModel;
 using System.Data;
 using System.Drawing;
 using System.Linq;
 using System.Text;
 using System.Windows.Forms;

 namespace 超市收银Demo
 {
     public partial class Main : Form
     {
         public Main()
         {
             InitializeComponent();
         }

         private void button_loadXML_Click(object sender, EventArgs e)
         {
             this.listBox1.Items.Clear();
             DataSet set = new DataSet();
             set.ReadXml(Application.StartupPath + "\\DataSource.xml");
             foreach (DataRowView view in set.Tables[].DefaultView)
             {
                 this.listBox1.Items.Add(view["ID"].ToString() + "   " + view["name"].ToString());
             }
             this.listBox1.SelectedIndex = ;
         }

         private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
         {
             string value = this.listBox1.SelectedItem.ToString();
             this.textBox1.Text = value;
         }
     }
 }
