C#操作读取、写入XML文档的实用方法

易采站长站为您分析C#操作读取、写入XML文档的实用方法，即即用.NET本身提供的Deserialize和Serialize进行反序列化和序列化XML文档，感兴趣的小伙伴们可以参考一下  

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");
    }
  }
}
