c# xml序列化和反序列化。也就是xml的解析和反解析。

用习惯了newTownSoft.json 的json反序列化。碰到xml是真的不习惯。

每次json反序列化都是直接把json丢到bejson网站生成一个实体类，稍微修改修改一点点变量名。然后直接newTownSoft反序列化，一下就得到一个实体类了。今天调某个接口，碰到xml。

记录如下。

xml

<response>
<functionID>setItemsPics</functionID>
<time>2017-09-07 15:51:04</time>
<ItemsIDList>
　　<itemIDInfo>
　　　　<operCode>0</operCode>
　　　　<operation>操作成功</operation>
　　</itemIDInfo>
<itemIDInfo>
　　<itemID>1125507057</itemID>
　　　　<operCode>0</operCode>
　　　　<operation>操作成功</operation>
　　</itemIDInfo>
</ItemsIDList>
</response>

实体类如下：先引用 using System.Xml.Serialization;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml.Serialization;
namespace DDTopManager.Response
{
    [XmlRoot("response")]
    public class RSPItemPicSet
    {
 
        //操作返回xml示例，按这个xml格式定义可序列化的实体类
        //        public string str = @"<response>
        //    <functionID>setItemsPics</functionID>
        //    <time>2017-09-07 15:51:04</time>
        //    <ItemsIDList>
        //        <itemIDInfo>
        //            <itemID>1125550957</itemID>
        //            <operCode>0</operCode>
        //            <operation>操作成功</operation>
        //        </itemIDInfo>
        //        <itemIDInfo>
        //            <itemID>1125507057</itemID>
        //            <operCode>0</operCode>
        //            <operation>操作成功</operation>
        //        </itemIDInfo>
        //    </ItemsIDList>
        //</response>";
        [XmlElement("functionID")]
        public string functionID { get; set; }
        [XmlElement("time")]
        public string time { get; set; }
 
        [XmlArray("ItemsIDList"), XmlArrayItem("itemIDInfo")]
        public List<itemIDInfo> ItemsIDList { get; set; }
        [XmlRoot("itemIDInfo")]
        public class itemIDInfo
        {
            [XmlElement("itemID")]
            public string itemID { get; set; }
            [XmlElement("operCode")]
            public string operCode { get; set; }
            [XmlElement("operation")]
            public string operation { get; set; }
        }
    }
 
 
}

　　引用(这是从str这个xml中反序列化到实体类)大致如下：

XmlSerializer se = new XmlSerializer(typeof(RSPOrdersListGet));
 
byte[] arry = Encoding.UTF8.GetBytes(str);
System.IO.Stream me = new System.IO.MemoryStream(arry);
RSPOrdersListGet rsp = (RSPOrdersListGet)se.Deserialize(me);

　　序列化如下：

RSPOrdersListGet RSPLG = new RSPOrdersListGet();
           RSPLG.functionID = "setItemsPics";
 
           List<itemIDInfo> itemidinfos = new List<itemIDInfo>();
           itemIDInfo idi = new itemIDInfo();
           idi.operation = "000";
           idi.operCode = "0011";
           idi.itemId = "aaa";
           itemidinfos.Add(idi);
           itemIDInfo idi1 = new itemIDInfo();
           idi1.operation = "000";
           idi1.operCode = "0011";
           idi1.itemId = "bbb";
           itemidinfos.Add(idi1);
           RSPLG.ItemsIDList = itemidinfos;
           XmlSerializer rSPOrdersListGet = new XmlSerializer(typeof(RSPOrdersListGet));
           rSPOrdersListGet.Serialize(Console.Out, RSPLG);

　　序列化的时候改命名空间编码等

XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
settings.IndentChars = "    ";
settings.NewLineChars = "\r\n";
settings.Encoding = Encoding.GetEncoding("gbk");
using (XmlWriter xmlWriter = XmlWriter.Create(sm, settings))
{
    // 强制指定命名空间，覆盖默认的命名空间  
    XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces();
    namespaces.Add(string.Empty, string.Empty);
    rSPOrdersListGet.Serialize(xmlWriter, RSTGS, namespaces);
    xmlWriter.Close();
};
