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>
