从 CObject 派生进行序列化会导致编译器访问错误
我创建了我的类 CData 并从 CObject 派生它，因为我需要序列化它。
class CData : public CObject
{
DECLARE_SERIAL(CData);
public:
CData();
virtual ~CData();
virtual void Serialize(CArchive& ar);
//Data
CString m_strName;
ULONG m_ulID;
CString m_strCorps;
CPoint m_Coordinate;
short m_sStatus;
};
我在文档类中使用了 vector 类型的向量。我在程序运行时使用 vecData.push_back(Data)（其中 Data 的类型为 CData）向向量添加新的 CData 对象。
但是当我尝试编译它时，我收到以下错误：
错误 C2248：“CObject::CObject”：无法访问私有成员 在“CObject”类中声明
我搜索了一下，发现它与 CObject 类不可复制或类似的东西有关！？！？...
有人知道如何解决这个问题吗？
I created my class CData and derived it from CObject, because I need to serialize it.
class CData : public CObject
{
DECLARE_SERIAL(CData);
public:
CData();
virtual ~CData();
virtual void Serialize(CArchive& ar);
//Data
CString m_strName;
ULONG m_ulID;
CString m_strCorps;
CPoint m_Coordinate;
short m_sStatus;
};
And I use a vector of type vector<CData> in my document class. I add new CData-objects to the vector during the runtime of the program using vecData.push_back(Data) (where Data is of type CData).
But when I try to compile this i get the following error:
error C2248: 'CObject::CObject' : cannot access private member
declared in class 'CObject'
I searched a bit and found out, that it has to do with the CObject-class to be non-copyable or something like this!?!?...
Does anyone know how to solve this problem?

CObject将复制构造函数声明为private，因此您需要自己为您的类实现复制构造函数（和赋值运算符重载）。CObject构造函数文档说：我希望这有帮助！
CObjectdeclares the copy constructor asprivate, so you need to implement the copy constructor (and assignment operator overload) for your class yourself. TheCObjectconstructor documentation says:I hope this helps!
您是否碰巧忘记了 .cpp 文件中的
IMPLMENT_SERIAL？Did you happen to forget
IMPLEMENT_SERIALin the .cpp-file?
