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.com",
RegTime = DateTime.Now
},
new UserInfo()
{
Id = 2,
UserName = "李四",
UserPass = "FDASDFAS",
Email = "lisi@163.com",
RegTime = DateTime.Now
},
new UserInfo()
{
Id = 3,
UserName = "王五",
UserPass = "FDASDFAS",
Email = "wangwu@163.com",
RegTime = DateTime.Now
},
new UserInfo()
{
Id = 4,
UserName = "赵六",
UserPass = "FDASDFAS",
Email = "zhaoliu@163.com",
RegTime = DateTime.Now
},
new UserInfo()
{
Id = 5,
UserName = "田七",
UserPass = "FDASDFAS",
Email = "tianqi@163.com",
RegTime = DateTime.Now
},
new UserInfo()
{
Id = 6,
UserName = "王八",
UserPass = "FDASDFAS",
Email = "wangba@163.com",
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://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <UserInfo> <Id>1</Id> <UserName>张三</UserName> <UserPass>FDASDFAS</UserPass> <Email>zhangsan@163.com</Email> <RegTime>2016-04-21T09:15:58.5576551+08:00</RegTime> </UserInfo> <UserInfo> <Id>2</Id> <UserName>李四</UserName> <UserPass>FDASDFAS</UserPass> <Email>lisi@163.com</Email> <RegTime>2016-04-21T09:15:58.5576551+08:00</RegTime> </UserInfo> <UserInfo> <Id>3</Id> <UserName>王五</UserName> <UserPass>FDASDFAS</UserPass> <Email>wangwu@163.com</Email> <RegTime>2016-04-21T09:15:58.5576551+08:00</RegTime> </UserInfo> <UserInfo> <Id>4</Id> <UserName>赵六</UserName> <UserPass>FDASDFAS</UserPass> <Email>zhaoliu@163.com</Email> <RegTime>2016-04-21T09:15:58.5576551+08:00</RegTime> </UserInfo> <UserInfo> <Id>5</Id> <UserName>田七</UserName> <UserPass>FDASDFAS</UserPass> <Email>tianqi@163.com</Email> <RegTime>2016-04-21T09:15:58.5576551+08:00</RegTime> </UserInfo> <UserInfo> <Id>6</Id> <UserName>王八</UserName> <UserPass>FDASDFAS</UserPass> <Email>wangba@163.com</Email> <RegTime>2016-04-21T09:15:58.5576551+08:00</RegTime> </UserInfo> </ArrayOfUserInfo>
