本文给大家分享一下C#操作（读取、写入）XML文档的实用方法，这种方法主要是对比较规范的XML文档进行操作，因为它（XML文档）和类对象是严格对应的，否则在反序列或序列化的时候会出现错误。其他的不用多说，直接看示例代码吧：
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml.Serialization;
namespace _01XMLSerialize
{
class Program
{
private static List<UserInfo> list = new List<UserInfo>()
{
new UserInfo()
{
Id = 1,
UserName = "张三" ,
UserPass = "FDASDFAS" ,
Email = "zhangsan@163测试数据" ,
RegTime = DateTime.Now
},
new UserInfo()
{
Id = 2,
UserName = "李四" ,
UserPass = "FDASDFAS" ,
Email = "lisi@163测试数据" ,
RegTime = DateTime.Now
},
new UserInfo()
{
Id = 3,
UserName = "王五" ,
UserPass = "FDASDFAS" ,
Email = "wangwu@163测试数据" ,
RegTime = DateTime.Now
},
new UserInfo()
{
Id = 4,
UserName = "赵六" ,
UserPass = "FDASDFAS" ,
Email = "zhaoliu@163测试数据" ,
RegTime = DateTime.Now
},
new UserInfo()
{
Id = 5,
UserName = "田七" ,
UserPass = "FDASDFAS" ,
Email = "tianqi@163测试数据" ,
RegTime = DateTime.Now
},
new UserInfo()
{
Id = 6,
UserName = "王八" ,
UserPass = "FDASDFAS" ,
Email = "wangba@163测试数据" ,
RegTime = DateTime.Now
}
};
static void Main( string [] args)
{
//序列化对象生成文件
WriteSingleXml();
//反序列化文件生成对象
ReadListXml();
Console.ReadKey();
}
/// <summary>
/// 从XML文件中反序列化对象
/// </summary>
private static void ReadListXml()
{
//反序列化文件
Console.WriteLine( "反序列化XML文件为集合" );
var reader = new XmlSerializer( typeof (List<UserInfo>));
using (var fs = File.OpenRead( "UserInfo.xml" ))
{
var result = reader.Deserialize(fs) as List<UserInfo>;
result.ForEach(Console.WriteLine);
}
Console.WriteLine( "反序列化成功" );
}
/// <summary>
/// 序列化对象到XML文件
/// </summary>
private static void WriteSingleXml()
{
//序列化集合为xml文件
Console.WriteLine( "序列化集合为XML文件" );
var reader = new XmlSerializer( typeof (List<UserInfo>));
//写入文件
using (var fs = File.OpenWrite( "UserInfo.xml" ))
{
reader.Serialize(fs, list);
}
Console.WriteLine( "写入成功" );
}
}
}
运行结果如图：
生成的XML文档如下:
<? xml version = "1.0" ?>
< ArrayOfUserInfo xmlns:xsi = "http://HdhCmsTestw3.org/2001/XMLSchema-instance" xmlns:xsd = "http://HdhCmsTestw3.org/2001/XMLSchema" >
