C#实现复杂XML的序列化与反序列化

这篇文章主要介绍了C#实现复杂XML的序列化与反序列化的方法,是非常实用的一个技巧,需要的朋友可以参考下

 

 

本文以一个实例的形式讲述了C#实现复杂XML的序列化与反序列化的方法。分享给大家供大家参考。具体方法如下：

已知.xml(再此命名default.xml)文件，请将其反序列化到一个实例对象。

Default.XML文件如下:

<?xml version="1.0" encoding="utf-8" ?>
<config>
 <rules>
  <rule name="namea">
   <params>
    <item name="p" type="get" pattern="(ios|android|)" />
    <item name="cid" type="get" pattern="(ios|android|)" />
    <item name="type" type="get" pattern="(ios|android|)" />
    <item name="sort" type="get" pattern="(ios|android|)" />
    <item name="action" type="post" pattern="(ios|android|)" />
    <item name="userAgent" type="header" pattern="(ios|android|)" />
   </params>
  </rule>
  
  <rule name="nameb">
   <params>
    <item name="p" type="get" pattern="(ios|android|)" />
    <item name="cid" type="get" pattern="(ios|android|)" />
    <item name="type" type="get" pattern="(ios|android|)" />
    <item name="sort" type="get" pattern="(ios|android|)" />
    <item name="action" type="post" pattern="(ios|android|)" />
    <item name="userAgent" type="header" pattern="(ios|android|)" />
   </params>
  </rule>
  
  <rule name="namec">
   <params>
    <item name="p" type="get" pattern="(ios|android|)" />
    <item name="cid" type="get" pattern="(ios|android|)" />
    <item name="type" type="get" pattern="(ios|android|)" />
    <item name="sort" type="get" pattern="(ios|android|)" />
    <item name="action" type="post" pattern="(ios|android|)" />
    <item name="userAgent" type="header" pattern="(ios|android|)" />
   </params>
  </rule>
  
  <rule name="named">
   <params>
    <item name="p" type="get" pattern="(ios|android|)" />
    <item name="cid" type="get" pattern="(ios|android|)" />
    <item name="type" type="get" pattern="(ios|android|)" />
    <item name="sort" type="get" pattern="(ios|android|)" />
    <item name="action" type="post" pattern="(ios|android|)" />
    <item name="userAgent" type="header" pattern="(ios|android|)" />
   </params>
  </rule>
 </rules>
</config>

 

C#示例代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml.Serialization;
 
namespace 多层级反序列
{
  [XmlType(TypeName = "config")]
  public class XmlConfig
  {
    [XmlArray("rules")]
    public List<rule> rules { get; set; }
  }
 
  [XmlType(TypeName = "rule")]
  public class rule
  {
    [XmlAttribute]
    public string name { get; set; }
 
    [XmlArray("params")]
    public List<paramsItem> @params { get; set; }
  }
 
  [XmlType(TypeName = "item")]
  public class paramsItem
  {
    [XmlAttribute]
    public string name { get; set; }
    [XmlAttribute]
    public string type { get; set; }
    [XmlAttribute]
    public string pattern { get; set; }
  }
 
  class Program
  {
    static void Main(string[] args)
    {
      /*
      XmlConfig xml1 = DeserializeFromXml<XmlConfig>("default.xml");
      XmlConfig xml = new XmlConfig();
      SerializeToXml<XmlConfig>("default.xml", xml);
      */
 
      XmlConfig xml1 = DeserializeFromXml<XmlConfig>("default.xml");
 
    }
 
    /// <summary>
    /// XML序列化某一类型到指定的文件
    /// </summary>
    /// <param name="filePath"></param>
    /// <param name="obj"></param>
    /// <param name="type"></param>
    public static void SerializeToXml<T>(string filePath, T obj)
    {
      try
      {
        using (System.IO.StreamWriter writer = new System.IO.StreamWriter(filePath))
        {
          System.Xml.Serialization.XmlSerializer xs = new System.Xml.Serialization.XmlSerializer(typeof(T));
          xs.Serialize(writer, obj);
        }
      }
      catch (Exception ex)
      {
      }
    }
    /// <summary>
    /// 从某一XML文件反序列化到某一类型
    /// </summary>
    /// <param name="filePath">待反序列化的XML文件名称</param>
    /// <param name="type">反序列化出的</param>
    /// <returns></returns>
    public static T DeserializeFromXml<T>(string filePath)
    {
      try
      {
        if (!System.IO.File.Exists(filePath))
          throw new ArgumentNullException(filePath + " not Exists");
 
        using (System.IO.StreamReader reader = new System.IO.StreamReader(filePath))
        {
          System.Xml.Serialization.XmlSerializer xs = new System.Xml.Serialization.XmlSerializer(typeof(T));
          T ret = (T)xs.Deserialize(reader);
          return ret;
        }
      }
      catch (Exception ex)
      {
        return default(T);
      }
    }
  }
}
