C #调用XML 文件

C# 调用XML 文件简单实例

需要引用XML 命名 using System.Xml;

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

namespace Wingtech.CSharpSample.XmlSample
{
    public partial class Display : Form
    {
        public Display()
        {
            InitializeComponent();
        }

        private void btnReadXML_Click(object sender, EventArgs e)
        {
            XmlDocument doc = new XmlDocument();
            try
            {
                doc.Load(@"....SampleXml.xml");
            }
            catch
            {
                MessageBox.Show("XML 文件加载错误！");
            }

            XmlNodeList elemetList1 = doc.GetElementsByTagName("server");
            for (int i = 0; i < elemetList1.Count; i++)
            {
                txtName.Text = elemetList1.Item(i).InnerText;
            }

            XmlNodeList elementList2 = doc.GetElementsByTagName("user");
            for(int j=0;j<elementList2.Count;j++)
            {
                txtPrice.Text = elementList2.Item(j).InnerXml;
            }

            XmlNodeList elementList3 = doc.GetElementsByTagName("pass");
            for (int j = 0; j < elementList3.Count; j++)
            {
                txtPass.Text = elementList3.Item(j).InnerXml;
            }
        }
    }
}

XML 实例 SampleXml.xml

<?xml version="1.0" encoding="utf-8" ?>
<merchandise>
  <server>Pen</server>
  <user>$0.4</user>
  <pass>HP</pass>
</merchandise>
  

结果
