【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; }
