使用MFC：：CArchive实现对象的持久化和反持久化

新建一个CPerson类

#include <afx.h>class CPerson : public CObject{DECLARE_SERIAL(CPerson)public:CPerson(void);CPerson(CString name, int age, bool gender = true);CString getName();CString getWords();void setWords(CString words);int getAge();bool isMale();void say();void say(CString msg);virtual void Serialize(CArchive& ar);virtual ~CPerson(void);private:CString m_name;int m_age;bool m_gender;CString m_words;};//实现文件#include "StdAfx.h"#include "Person.h"CPerson::CPerson(void){m_name = _T("谁");m_age = 2;m_gender = true;}CPerson::CPerson(CString name, int age, bool gender){m_name = name;m_age = age;m_gender = gender;}CString CPerson::getName(){return m_name;}CString CPerson::getWords(){return m_words;}void CPerson::setWords(CString words){m_words = words;}int CPerson::getAge(){return m_age;}bool CPerson::isMale(){return m_gender;}void CPerson::say(){say(m_words);}void CPerson::say(CString msg){_tprintf(_T("%s说: %s/r/n"), m_name, m_words);}void CPerson::Serialize(CArchive& ar){if (ar.IsStoring()){ar << this->m_name << this->m_age << this->m_gender << this->m_words;}else{ar >> this->m_name >> this->m_age >> this->m_gender >> this->m_words;}}CPerson::~CPerson(void){}IMPLEMENT_SERIAL(CPerson, CObject, 1) 

 

测试程序，在main（）中创建2个CPerson对象，然后将其持久化到.archive文件中，再将其反持久化出来

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[]){setlocale(LC_ALL, "chs");//创建两个待写入的对象CPerson chain(_T("钱恩"), 25, true);chain.setWords(_T("快到吃午饭的时间了……"));CPerson who;who.setWords(_T("我是谁？"));CFile file(_T("persons.archive"), CFile::modeCreate | CFile::modeWrite);CArchive ar(&file, CArchive::store);//序列化进入ar << &chain << &who;ar.Close();file.Close();CFile Rfile(_T("persons.archive"), CFile::modeRead);CArchive Rar(&Rfile, CArchive::load);CPerson *p1, *p2;//序列化出来Rar >> p1 >> p2;p1->say();p2->say();delete p1;delete p2;return 0;}
