C#实现复杂XML的序列化与反序列化
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); } } } }
