C#完成龐雜XML的序列化與反序列化

C#完成龐雜XML的序列化與反序列化。本站提示廣大學習愛好者：（C#完成龐雜XML的序列化與反序列化）文章只能為提供參考，不一定能成為您想要的結果。以下是C#完成龐雜XML的序列化與反序列化正文

本文以一個實例的情勢講述了C#完成龐雜XML的序列化與反序列化的辦法。分享給年夜家供年夜家參考。詳細辦法以下：

已知.xml(再此定名default.xml)文件，請將其反序列化到一個實例對象。

Default.XML文件以下:

<?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>

using System.Linq;
using System.Text;
using System.Xml.Serialization;

    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; }

    public string pattern { get; set; }
  }

  class Program

      XmlConfig xml1 = DeserializeFromXml<XmlConfig>("default.xml");

    }

        {

          xs.Serialize(writer, obj);
        }
      }
      catch (Exception ex)
      {
      }
    }
    /// <summary>

    {
      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);
      }
    }
  }
}
