今天我们来看一下在C#中对象序列化XML的方法。

不得不说，在这个Json横行的年代，XML虽然式微，但也的确是一股子清流。（个人感觉）

不多说，直接开始。

首先先说怎么用

需要用到的是这两个命名空间（主要）

using System.Xml;using System.Xml.Serialization;

然后序列化和反序列化的方式和Json一样。（后面提供封装方法）

string result = XmlSerializeHelper.Serialize<test>(new test { name = "Seven", cardId = "663927", age = 15, currentTime = DateTime.Now }); Console.WriteLine(result); test test2 = XmlSerializeHelper.DeSerialize<test>(result);

下面来看封装类

public class XmlSerializeHelper { //对象转XML public static string ObjToXml(object obj) { using (MemoryStream Stream = new MemoryStream()) { XmlSerializer xml = new XmlSerializer(obj.GetType()); xml.Serialize(Stream, obj); Stream.Position = 0; StreamReader sr = new StreamReader(Stream); return sr.ReadToEnd(); } } public static string Serialize<T>(T obj) { return Serialize<T>(obj, Encoding.UTF8); } /// <summary> /// 实体对象序列化成xml字符串 /// </summary> /// <typeparam name="T"></typeparam> /// <param name="obj"></param> /// <returns></returns> public static string Serialize<T>(T obj, Encoding encoding) { try { if (obj == null) { throw new ArgumentNullException("obj"); } var ser = new XmlSerializer(obj.GetType()); using (var ms = new MemoryStream()) { using (var writer = new XmlTextWriter(ms, encoding)) { writer.Formatting = Formatting.Indented; ser.Serialize(writer, obj); } var xml = encoding.GetString(ms.ToArray()); xml = xml.Replace("xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"", ""); xml = xml.Replace("xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"", ""); xml = Regex.Replace(xml, @"\s{2}", ""); xml = Regex.Replace(xml, @"\s{1}/>", "/>"); return xml; } } catch (Exception ex) { throw ex; } } /// <summary> /// 反序列化xml字符为对象，默认为Utf-8编码 /// </summary> /// <typeparam name="T"></typeparam> /// <param name="xml"></param> /// <returns></returns> public static T DeSerialize<T>(string xml) where T : new() { return DeSerialize<T>(xml, Encoding.UTF8); } /// <summary> /// 反序列化xml字符为对象 /// </summary> /// <typeparam name="T"></typeparam> /// <param name="xml"></param> /// <param name="encoding"></param> /// <returns></returns> public static T DeSerialize<T>(string xml, Encoding encoding) where T : new() { try { var mySerializer = new XmlSerializer(typeof(T)); using (var ms = new MemoryStream(encoding.GetBytes(xml))) { using (var sr = new StreamReader(ms, encoding)) { return (T)mySerializer.Deserialize(sr); } } } catch (Exception e) { return default(T); } } }Class Of XmlSerializeHelper

好了，板砖要紧，先到这里。
