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[0].DefaultView)
            {
                this.listBox1.Items.Add(view["ID"].ToString() + "   " + view["name"].ToString());
            }
            this.listBox1.SelectedIndex = 0;
        }

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