XML 序列化：可以将对象序列化为XML文件，或者将XML文件反序列化为对象还有种方法 使用LINQ TO XML或者反序列化的方法从XML中读取数据。

最简单的方法就是 .net framework提供的，只需要定义好xml数据格式，定义好对象即可。

1、调用方法：

using RenosData.RDBao.EvidenceUploadModel.Models;
using RenosData.RDBao.EvidenceUploadModel.Parsers;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml.Linq;
using System.Xml.Serialization;

namespace TestApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            string path = @"C:\Users\PEPE\Desktop\证据接口结构.xml";
            FileStream stream = new FileStream(path, FileMode.Open);
            EvidenceFilesModel dep = (EvidenceFilesModel)XMLParser.Deserialize(typeof(EvidenceFilesModel), stream);
            stream.Close();
        }
    }
}

2、xml解析类

using RenosData.RDBao.EvidenceUploadModel.Models;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml.Serialization;

namespace RenosData.RDBao.EvidenceUploadModel.Parsers
{
    public class XMLParser
    {
        public T Deserialize<T>(T t, string s)
        {
            using (StringReader sr = new StringReader(s))
            {
                XmlSerializer xz = new XmlSerializer(t.GetType());
                return (T)xz.Deserialize(sr);
            }
        }

        public EvidenceFilesModel Convert(string xml)
        { //将xml反序列化成对象
            EvidenceFilesModel b = new EvidenceFilesModel();
            return Deserialize<EvidenceFilesModel>(b, xml);
        }

        #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XML文件
        /// <summary>
        /// 序列化XML文件
        /// </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();
            //创建序列化对象
            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();
            return str;
        }
        #endregion
    }

}

3、xml对象

根据xml定义的对象如下

eg 根目录类,其他的类就按xml格式一路下去

/// <summary>
    /// 证据接口结构模型
    /// </summary>
    [Serializable]
    [XmlRoot("EvidenceFiles")]
    public class EvidenceFilesModel
    {
        /// <summary>
        /// 证据包信息
        /// </summary>
        public EvidencePackageModel EvidencePackage { get; set; }

        /// <summary>
        /// 证据信息明细
        /// </summary>
        [XmlArrayItem("Evidence")]
        public  List<EvidenceModel> Evidences { get; set; }
    }

注意特性：[XmlArrayItem("Evidence")] 这个下面是会有多个分支

4、XML代码

<?xml version="1.0" encoding="utf-8"?>
<EvidenceFiles xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <!--证据包信息-->
