vc++上的MFC的對象序列化和還原序列化

注意點:
 1. 必須類型序列化聲明
    DECLARE_SERIAL( Person )
 
 2. 必須寫出實現宏
 IMPLEMENT_SERIAL(Person, CObject, VERSIONABLE_SCHEMA | 2)
 
 3. 重寫CObject中的Serialize函數
 void Person::Serialize( CArchive& ar )
 {
  CObject::Serialize(ar);
  //關鍵代碼
  if(ar.IsStoring()) {
   //序列化
   ar << this->age << this->sex << this->name;
  } else {
   //還原序列化
   ar >> this->age >> this->sex >> this->name;
  }
 }
