C#实现复杂XML的序列化与反序列化

来源：互联网发布：苹果壁纸软件下载编辑：程序博客网时间：2024/06/06 08:29

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);            }        }    }}

希望本文所述对大家的C#程序设计有所帮助。
