XML的序列化和反序列化

最近在做一个需求，是把passport返回的结果（xml）转变为我自己定义的C#对象。

首先提供一个序列化的工具类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Data;
using System.Xml;
using System.Xml.Serialization;
 
/// <summary>
/// Xml序列化与反序列化
/// </summary>
public class XmlUtil
{
    #region 反序列化
    /// <summary>
    /// 反序列化
    /// </summary>
    /// <param name="type">类型</param>
    /// <param name="xml">XML字符串</param>
    /// <returns></returns>
    public static object Deserialize(Type type,string xml)
    {
        try
        {
            using (StringReader sr = new StringReader(xml))
            {
                XmlSerializer xmldes = new XmlSerializer(type);
                return xmldes.Deserialize(sr);
            }
        }
        catch (Exception e)
        {
 
            return null;
        }
    }
    /// <summary>
    /// 反序列化
    /// </summary>
    /// <param name="type"></param>
    /// <param name="xml"></param>
    /// <returns></returns>
    public static object Deserialize(Type type,Stream stream)
    {
        XmlSerializer xmldes = new XmlSerializer(type);
        return xmldes.Deserialize(stream);
    }
    #endregion
 
    #region 序列化
    /// <summary>
    /// 序列化
    /// </summary>
    /// <param name="type">类型</param>
    /// <param name="obj">对象</param>
    /// <returns></returns>
    public static string Serializer(Type type,object obj)
    {
        MemoryStream Stream = new MemoryStream();
        XmlSerializer xml = new XmlSerializer(type);
        try
        {
            //序列化对象
            xml.Serialize(Stream,obj);
        }
        catch (InvalidOperationException)
        {
            throw;
        }
        Stream.Position = 0;
        StreamReader sr = new StreamReader(Stream);
        string str = sr.ReadToEnd();
         
        sr.dispose();
        Stream.dispose();
 
        return str;
    }
 
    #endregion
}

假如xml是：

public string testXML = "<?xml version=\"1.0\" encoding=\"gb2312\"?><user><id>12654</id><name>wangjue</name><displayName>王xx</displayName><token>DBDF3367E9F6490ABB8AC711F94E24CE</token><departmentCode>IT</departmentCode><departmentName>技术部</departmentName></user>";

对这个xml进行一下序列化。

首先定义我的C#类

[XmlRoot("user")]//序列化根节点需要使用的名称
    public class PassportUser
    {
        [XmlElement("id")]//序列化子节点需要使用的名称
        public int Id { set; get; }
        [XmlElement("name")]
        public string Name { set; get; }
        [XmlElement("displayName")]
        public string displayName { set; get; }
        [XmlElement("token")]
        public string Token { set; get; }
        [XmlElement("departmentCode")]
        public string DepartmentCode { set; get; }
        [XmlElement("departmentName")]
        public string DepartmentName { set; get; }
    }

调用：

var result = Deserialize(typeof(PassportUser),testXML);

成功实现。
