首先要确定好XML文件的位置,最好是放在程序的debug文件中,放在其他地方也可以,要写上绝对路径
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;
using System.Xml;//引入命名空间
namespace XMLDemo
{
public partial class FrmReadXML : Form
{
public FrmReadXML()
{
InitializeComponent();
}
private void btnLoadXML_Click(object sender, EventArgs e)
{
XmlDocument objDoc = new XmlDocument(); //【1】创建XML文档操作对象
objDoc.Load("StuScore.xml"); //【2】加载XML文件到文档对象中
XmlNode rootNode = objDoc.DocumentElement; //【3】获取XML文档根目录
List<Student> list = new List<Student>();//创建对象集合
foreach (XmlNode stuNode in rootNode.ChildNodes) //【4】遍历根节点(根节点包含所有节点)
{
if (stuNode.Name == "Student")
{
Student objStu = new Student();
foreach (XmlNode subNode in stuNode) //【5】遍历子节点
{
switch (subNode.Name)//根据子节点的名称封装到对象的属性
{
case "StuName":
objStu.StuName = subNode.InnerText;//获取《节点名称》对应的《节点值》
break;
case "StuAge":
objStu.StuAge = Convert.ToInt16(subNode.InnerText);
break;
case "Gender":
objStu.Gender = subNode.InnerText;
break;
case "ClassName":
objStu.ClassName = subNode.InnerText;
break;
}
}
list.Add(objStu);
}
}
this.dgvStuList.DataSource = list;
}
//显示版本信息
private void btnShowVersion_Click(object sender, EventArgs e)
{
//创建XML读取器
XmlTextReader tReader = new XmlTextReader("StuScore.xml");
string info = string.Empty;
//循环查询
while (tReader.Read())
{
if (tReader.Name == "Version")
{
info = "版本:" + tReader.GetAttribute("vNo") + " 发布时间:"
+ tReader.GetAttribute("pTime");
break;
}
}
MessageBox.Show(info,"数据版本");
}
}
}
