Linq读xml

读取 XML最方便的当然是用LINQ！可以参考博客上的这篇文章：http://www.wyjexplorer.cn/Blog/View /EC3073A1BDFB9D90.html

Demo

1.搞个XML文件：

<?xml version="1.0" encoding="utf-8" ?>
<Contacts>
    <Person>
        <Id>1</Id>
        <Name>**er</Name>
        <Mobile>13838389438</Mobile>
        <Address>No.250, **ing Road</Address>
    </Person>
    <Person>
        <Id>2</Id>
        <Name>Dick</Name>
        <Mobile>1234567890123</Mobile>
        <Address>No.13, 2B Road, ** City</Address>
    </Person>
    <Person>
        <Id>3</Id>
        <Name>**ter</Name>
        <Mobile>987654321098</Mobile>
        <Address>No.38, SB Street</Address>
    </Person>
</Contacts>

2.给他创建一个数据模型类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
 
/// <summary>
/// Summary description for Person
/// </summary>
namespace LinqXMLGridViewDemo
{
    public class Person
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Mobile { get; set; }
        public string Address { get; set; }
 
        public Person()
        {
            //
            // TODO: Add constructor logic here
            //
        }
    }
}

3. 页面上拖个GridView，后台代码这样写：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Xml.Linq;
using LinqXMLGridViewDemo;
 
public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        var query = GetXMLData();
 
        gvContact.DataSource = query;
        gvContact.DataBind();
    }
 
    private List<Person> GetXMLData()
    {
        var xDoc = XDocument.Load(Server.MapPath("~/App_Data/Data.xml"));
        var query = (from person in xDoc.Descendants("Person")
                     select new Person()
                     {
                         Id = Convert.ToInt32(person.Element("Id").Value),
                         Name = person.Element("Name").Value,
                         Mobile = person.Element("Mobile").Value,
                         Address = person.Element("Address").Value
                     }).ToList();
        return query;
    }
 
}

有图有真相：
