【MFC】序列化(Serialize)、反序列化(Deserialize)

1、首先在头文件里面声明

DECLARE_SERIAL(CSelectionSerial)

2、重写CObject的Serialize函数

virtual void Serialize(CArchive& ar)
{
   CObject::Serialize(ar);
   //关键代码
   if(ar.IsStoring()) 
  {
         //序列化
         ar << this->xxx;
    }
   else 
   {
         //反序列化
         ar >>xxx;
    }
}

3、在类开始出定义

 IMPLEMENT_SERIAL(Person, CObject, VERSIONABLE_SCHEMA | 2)

下面给出一个列子:

1、序列化类.h文件

#pragma once

// CSelectionSerial 命令目标
class CSelectionSerial : public CObject
{
public:
    DECLARE_SERIAL(CSelectionSerial) //必要内容
    CSelectionSerial();
    virtual ~CSelectionSerial();
    //序列化重写
    //参数ar,CArchive类型
    virtual void Serialize(CArchive& ar); //必要内容
    void SetCurrent(const int index);
    int GetCurrent();
   void SetFile(const CString file);
   CString GetFile();

private: int m_Current;
   CString m_File; };

2、序列化类.cpp文件

// SelectionSerial.cpp : 实现文件
//

#include "stdafx.h"
#include "SelectionSerial.h"

// CSelectionSerial
IMPLEMENT_SERIAL(CSelectionSerial,CObject,VERSIONABLE_SCHEMA | 2) //必要内容
CSelectionSerial::CSelectionSerial()
{
}

CSelectionSerial::~CSelectionSerial()
{
}


// CSelectionSerial 成员函数

void CSelectionSerial::Serialize(CArchive& ar) //必要内容
{
    CObject::Serialize(ar);
    if(ar.IsStoring())
    {
        //序列化
        ar<<this->m_File;
        ar<<this->m_Current;
    }
    else
    {
        //反序列化
        ar>>this->m_File;
        ar>>this->m_Current;
    }
}

void CSelectionSerial::SetCurrent(int index)
{
    m_Current=index;
}

int CSelectionSerial::GetCurrent()
{
    return m_Current;
}
void CSelectionSerial::SetFile(CString file) { m_File=file; } CString CSelectionSerial::GetFile() { return m_File; }

3、序列化

void Serializable(CSelectionSerial* serial,CString filePath)
{
    CFile file(filePath,CFile::modeCreate|CFile::modeWrite);
    file.SeekToBegin();
    ::CArchive arStore(&file,CArchive::store);
    arStore.WriteObject(serial);
    arStore.Flush();
    arStore.Close();
    file.Close();
}

4、反序列化

CSelectionSerial* DeSerializable(CString filePath)
{
    CFile file(filePath,CFile::modeRead);
    file.SeekToBegin();
    ::CArchive arLoad(&file,CArchive::load);
    CSelectionSerial* serial = (CSelectionSerial*)arLoad.ReadObject(RUNTIME_CLASS(CSelectionSerial));
    arLoad.Close();
    file.Close();
    return serial;
}
