我创建了个新类

class Squiggle : public Shape 

{

 DECLARE_SERIAL(Squiggle)  

public:

 Squiggle(COLORREF color,int width,CPoint start);

 virtual ~Squiggle();

 virtual void Draw(CDC *pDC);

 virtual void Update(CPoint point);

 virtual void Serialize(CArchive &ar);

protected:

 Squiggle();

 CArray<CPoint,CPoint> m_data;

};

总是出错：error C2143: syntax error : missing ';' before '<'

error C2501: 'CArray' : missing storage-class or type specifiers

error C2059: syntax error : '<'

error C2238: unexpected token(s) preceding ';'

是怎么回事啊？？？
