【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"// CSelectionSerialIMPLEMENT_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;}
