C#操作读取、写入XML文档的实用方法

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 = "[e-mail]",
        regtime = datetime.now
      },
      new userinfo()
      {
        id = 2,
        username = "李四",
        userpass = "fdasdfas",
        email = "[e-mail]",
        regtime = datetime.now
      },
      new userinfo()
      {
        id = 3,
        username = "王五",
        userpass = "fdasdfas",
        email = "[e-mail]",
        regtime = datetime.now
      },
      new userinfo()
      {
        id = 4,
        username = "赵六",
        userpass = "fdasdfas",
        email = "[e-mail]",
        regtime = datetime.now
      },
      new userinfo()
      {
        id = 5,
        username = "田七",
        userpass = "fdasdfas",
        email = "[e-mail]",
        regtime = datetime.now
      },
      new userinfo()
      {
        id = 6,
        username = "王八",
        userpass = "fdasdfas",
        email = "[e-mail]",
        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>[e-mail]</email>
  <regtime>2016-04-21t09:15:58.5576551+08:00</regtime>
