vc++上的MFC的对象序列化和反序列化

注意点:

1. 必须类型序列化声明

DECLARE_SERIAL( Person )

2. 必须写出实现宏

IMPLEMENT_SERIAL(Person, CObject, VERSIONABLE_SCHEMA | 2)

3. 重写CObject中的Serialize函数

void Person::Serialize( CArchive& ar )

{

CObject::Serialize(ar);

//关键代码

if(ar.IsStoring()) {

//序列化

ar << this->age << this->sex << this->name;

} else {

//反序列化

ar >> this->age >> this->sex >> this->name;

}

}

序列化后的数据

//Person.h
#pragma once
#include <afx.h>
#include <string>
#include <atlstr.h>

using namespace std;

class Person: public CObject
{
private:
//注意MFC 不支持 标准std:string对象序列化, boost库支持std:string
CString name;
int age;
char sex;
public:
DECLARE_SERIAL( Person )

Person(void);

Person(CString name, int age, char sex);

virtual ~Person(void);

virtual void Serialize(CArchive& ar);

void setName(CString pName);

CString getName();

void setAge(int age);

int getAge();

void setSex(char sex);

char getSex();
};

//Person.cpp
#include "StdAfx.h"
#include "Person.h"
#include <afx.h>
#include <string>

//必须写出实现宏
IMPLEMENT_SERIAL(Person, CObject, VERSIONABLE_SCHEMA | 2)

Person::Person(void)
{
}

Person::Person( CString name, int age, char sex )
{
this->name = name;
this->age = age;
this->sex = sex;
}

Person::~Person(void)
{
}

void Person::setName(  CString name)
{
this->name = name;
}

CString Person::getName()
{
return this->name;
}

void Person::setAge( int age )
{
this->age = age;
}

int Person::getAge()
{
return this->age;
}

void Person::setSex( char sex )
{
this->sex = sex;
}

char Person::getSex()
{
return this->sex;
}

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