C# XML序列化反序列化教程

最近遇到与第三方对接，对方接口接收的是xml格式的报文；而我这边自己平台采用的是json格式的报文；无奈之下只能寻找json与xml共用一个对象序列化/反序列化的办法，以下代码是c#操作xml序列化反序列化以及xml序列化时一些特殊选项设置，例如压缩、编码、命名空间等，xml序列化库是基于微软原生xml库进行实现。

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml;
using System.Xml.Serialization;

namespace TestXml
{
    [XmlRoot("SyncReceiptInfo")]/*xml根节点名称，若类名与节点名一致，则忽略*/
    [Serializable]/*打上此属性表示此对象可被序列化*/
    public class request_instore
    {
         [XmlElement("userId")]/*xml节点名称，字段名与节点名一致，则忽略*/
        public string ownerCode { get; set; }
   

        public string warehouseCode { get; set; }
  

        [XmlElement("sender")]
        public instroe_sender sender { get; set; }

        [XmlArrayItem("item")]/*xml集合中子节点名称*/
        [XmlArray("items")]/*xml集合节点名称*/
        public List<instroe_items> items { get; set; }

    }

    [Serializable]
    public class instroe_sender
    {
        public string name { get; set; }
    }

    [Serializable]
    public class instroe_items
    {
        public string itemSkuCode { get; set; }
  
        public string itemQuantity { get; set; }
        [XmlIgnore]/*打上此属性，表示xml序列化/反序列化将忽略此字段*/
        public string itemEpc { get; set; }
    }
