[mfc]关于串行化(Serialize)的学习
本帖最后由 小可爱～ 于 2017-1-28 22:51 编辑这是界面
这是line的头文件
#pragma once
#include "afx.h"
class CLine :
public CObject
{
public:
CPoint m_poFrom;
CPoint m_poTo;
COLORREF m_clrLine;
public:
CLine()
{
}
CLine::CLine(CPoint from, CPoint to)
{
this->m_poFrom = from;
this->m_poTo = to;
}
CLine::CLine(CPoint from, CPoint to, COLORREF clrLine)
{
this->m_poFrom = from;
this->m_poTo = to;
this->m_clrLine = clrLine;
}
void setCLine(CPoint from, CPoint to)
{
this->m_poFrom = from;
this->m_poTo = to;
}
void setCLine(CPoint from, CPoint to, COLORREF clrLine)
{
this->m_poFrom = from;
this->m_poTo = to;
this->m_clrLine = clrLine;
}
CLine::~CLine()
{
}
DECLARE_SERIAL(CLine)
virtual void Serialize(CArchive& ar);
};
这是line.cpp文件源码
#include "stdafx.h"
#include "Line.h"
IMPLEMENT_SERIAL(CLine, CObject, 2 | VERSIONABLE_SCHEMA)
void CLine::Serialize(CArchive& ar)
{
CObject::Serialize(ar);
if (ar.IsStoring())
{ // storing code
ar << m_poFrom << m_poTo << m_clrLine;
}
else
{ // loading code
UINT nSchema = ar.GetObjectSchema();
switch (nSchema)
{
case 1://这个是版本一的输出
ar >> m_poFrom >> m_poTo;
m_clrLine = RGB(0, 0, 0);
break;
case 2:
ar >> m_poFrom >> m_poTo >> m_clrLine;
break;
default:
AfxThrowArchiveException(CArchiveException::badSchema);
break;
}
}
}
这是主要源码

int b = 100;
CArchive ArcFile(&file, CArchive::store);
//现在需要保存 任何数据类型都是比较简单的事
ArcFile << a << b;//写入变量的值
m_line.setCLine(CPoint(10, 10), CPoint(100, 100));
ArcFile << &m_line;
//line.Serialize(ArcFile);//写入对象的属性 //使用这个方法的话就不能做多版本了
ArcFile.Close();
file.Close();
MessageBox(TEXT("串行化成功"), TEXT("提示:"), 0);
}

}
return hbr;
} 完全不懂 看标题还以为是串口通信的。。。{:1_907:}
这个学名应该叫对象的序列化和反序列化吧
