C# 序列化和反序列化(Xml，二进制)

序列化:将对象保存为文本文件或二进制文件；

反序列:将文本文件或二进制文件还原为对象；

1.Xml文件

1.1.创建StudentInfo类

using System.Collections.Generic;
using System.Xml.Serialization;
using System;
[Serializable]
[XmlRoot("Student")]
public class StudentInfo
{
    [XmlElement("Name")]
    public string name;
    [XmlElement("ID")]
    public int id;
    [XmlElement("Gender")]
    public string gender;
    [XmlArray("Hobby")]
    public List<HobbyInfo> hobby;
    public StudentInfo() {}
    public StudentInfo(string _name,int _id,string _gender,List<HobbyInfo> _hobby)
    {
        this.name = _name;
        this.id = _id;
        this.gender = _gender;
        this.hobby = _hobby;
    }
}

1.2.创建HobbyInfo类

using System;
using System.Xml.Serialization;
[Serializable]
public class HobbyInfo
{
    [XmlAttribute("Name")]
    public string name;
    [XmlAttribute("Info")]
    public string info;
    public HobbyInfo() { }
    public HobbyInfo(string _name,string _info)
    {
        this.name = _name;
        this.info = _info;
    }
}

1.3.序列化（生成Xml文件）

   void Start()
    {
        InitData();
        //StudentInfo info= XMLDeSerialize();
        //Debug.Log(info.name);
    }
    /// <summary>
    /// 初始化数据
    /// </summary>
    void InitData()
    {
        HobbyInfo info1 = new HobbyInfo("篮球", "篮球info");
        HobbyInfo info2 = new HobbyInfo("读书", "读书info");
        List<HobbyInfo> info = new List<HobbyInfo>();
        info.Add(info1);
        info.Add(info2);
        StudentInfo student = new StudentInfo("张三",1,"男", info);
        XMLSerialize(student);
    }
    /// <summary>
    /// xml序列化
    /// </summary>
    void XMLSerialize(StudentInfo student)
    {
        string path = Application.dataPath + "/student.xml";
        using (FileStream fs=new FileStream(path,FileMode.Create,FileAccess.ReadWrite))
        {
            XmlSerializer xml = new XmlSerializer(student.GetType());
            xml.Serialize(fs, student);
        }
    }

生成的Xml如下图

1.4.反序列化

    /// <summary>
    /// xml反序列化
    /// </summary>
    /// <returns></returns>
    StudentInfo XMLDeSerialize()
    {
        StudentInfo student = new StudentInfo();
        string path = Application.dataPath + "/student.xml";
        using (FileStream fs = new FileStream(path, FileMode.Open, FileAccess.ReadWrite))
        {
            XmlSerializer xml = new XmlSerializer(typeof(StudentInfo));
            student=(StudentInfo)xml.Deserialize(fs);

        }
        return student;
    }

2.二进制文件

2.1序列化（生成二进制文件）

    void BinarySerialize(StudentInfo student)
    {
        string path = Application.dataPath + "/student.bytes";
        using (FileStream fs = new FileStream(path, FileMode.Create, FileAccess.ReadWrite))
        {
            BinaryFormatter bf = new BinaryFormatter();
            bf.Serialize(fs, student);
        }
    }

2.2反序列化

    StudentInfo BinaryDeSerialize()
    {
        StudentInfo student=new StudentInfo();
        string path = Application.dataPath + "/student.bytes";
        using (FileStream fs = new FileStream(path, FileMode.Open, FileAccess.ReadWrite))
        {
            BinaryFormatter bf = new BinaryFormatter();
            student = (StudentInfo)bf.Deserialize(fs);
        }
        return student;
    }
