IXmlSerializable接口:

使用该接口可以帮助处理不能被序列化和反序列化的特殊类得到处理,

使特殊类继承IXmlSerializable接口 ,实现其中的读写方法,检测到读写方法被重写之后,

便会按照自定义实现的接口来实现方法。

存储的XML的文件样式(注意对照XML存储样式来理解读取和存储的代码)

特别注意在代码中的读取包裹节点时候先要跳过“根节点”,code Line81;

自定义实现支持序列化与反序列化的字典

using System.Collections.Generic;
using System.Xml;
using System.Xml.Schema;
using System.Xml.Serialization;

namespace Building.XML.SerializerDic
{
    /// <summary>
    /// 支持序列化与反序列化的字典
    /// </summary>

    public class SerializerDictionary<TKey,TValue>:Dictionary<TKey,TValue>,IXmlSerializable
    {
        public XmlSchema GetSchema()
        {
            return null;
        }

        /// <summary>
        /// 反序列化 读取XML文件调用
        /// </summary>
        /// <param name="reader"></param>
        /// <exception cref="NotImplementedException"></exception>
        public void ReadXml(XmlReader reader)
        {
            //新建写入器 反序列化工具
            XmlSerializer xmlSerializerKey = new XmlSerializer(typeof(TKey));
            XmlSerializer xmlSerializerValue = new XmlSerializer(typeof(TValue));
            
            //跳过根节点
            reader.Read();
            
            while (reader.NodeType!=XmlNodeType.EndElement)
            {
                TKey tk = (TKey)xmlSerializerKey.Deserialize(reader);
                TValue tv = (TValue) xmlSerializerValue.Deserialize(reader);
                this.Add(tk,tv);//添加到容器中
            }
        }

        /// <summary>
        /// 序列化 写入XML文件时候调用
        /// </summary>
        /// <param name="writer"></param>
        /// <exception cref="NotImplementedException"></exception>
        public void WriteXml(XmlWriter writer)
        {
           //新建写入器 序列化工具
           XmlSerializer xmlSerializerKey = new XmlSerializer(typeof(TKey));
           XmlSerializer xmlSerializerValue = new XmlSerializer(typeof(TValue));

           foreach (KeyValuePair<TKey,TValue> kv in this)
           {
               xmlSerializerKey.Serialize(writer,kv.Key);
               xmlSerializerValue.Serialize(writer,kv.Value);
           }
        }
    }
}

测试代码:

using System.Collections.Generic;
using System.IO;
using System.Xml.Serialization;
using UnityEngine;

namespace Building.XML.SerializerDic
{
    public class Test4
    {
        public int num = 4;
        public SerializerDictionary<int, string> sDic;
    }
    public class XMLDemo3:MonoBehaviour
    {
        private void Start()
        {
            string path = Application.persistentDataPath + "/XMLDemo4.xml";
            print(path);
            Test4 test4 = new Test4();
            test4.sDic = new SerializerDictionary<int, string>() {{1, "Tony"}, {2, "Tom"}, {3, "Frank"}};
            using (StreamWriter streamWriter=new StreamWriter(path))
            {
                XmlSerializer xmlSerializerWrite = new XmlSerializer(typeof(Test4));
                xmlSerializerWrite.Serialize(streamWriter,test4);
            }
            
            //进行反序列化读取
            if (File.Exists(path))
            {
                using (StreamReader streamReader=new StreamReader(path))
                {
                    XmlSerializer xmlSerializerRead = new XmlSerializer(typeof(Test4));
                    Test4 test4Read=xmlSerializerRead.Deserialize(streamReader) as Test4;
                    foreach (KeyValuePair<int,string> pair in test4Read.sDic)
                    {
                       Debug.Log("key:"+pair.Key+",Value:"+pair.Value);
                    }
                }
