想了解C#操作读取、写入XML文档的实用方法的相关内容吗,一个人的长征在本文为您仔细讲解C#操作读取、写入XML文档的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:C#读取XML文档,C#写入XML文档,下面大家一起来学习吧。

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">
