C#实现复杂XML的序列化与反序列化

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);
   }
  }
 }
}
