我在tetrisdoc.h头文件中获取了'm_colorGrid'的未声明标识符，尽管它声明了：

请参阅下面的代码段：

// TetrisDoc.h : interface of the CTetrisDoc class

//

#pragma once

#include "Figure.h"

typedef CList IntList;

const int FIGURE_ARRAY_SIZE = 7;

class CTetrisDoc : public CDocument

{

protected: // create from serialization only

CTetrisDoc();

DECLARE_DYNCREATE(CTetrisDoc)

public:

virtual ~CTetrisDoc();

private:

ColorGrid m_colorGrid;

Figure m_activeFigure, m_nextFigure;

int m_iScore;

IntList m_scoreList;

const CRect NEXT_AREA, SCORE_AREA;

static Figure m_figureArray[FIGURE_ARRAY_SIZE];

// Operations

public:

void SaveScoreList();

virtual void Serialize(CArchive& archive);

int GetScore() const { return m_iScore; }

const IntList* GetScoreList() { return &m_scoreList; }

const ColorGrid* GetGrid()

{

ColorGrid* pm_colorGrid = &m_colorGrid;

return pm_colorGrid;

}

const Figure& GetActiveFigure() { return m_activeFigure; }

const Figure& GetNextFigure() { return m_nextFigure; }

void LeftArrowKey();

void RightArroyKey();

void UpArrowKey();

void DownArrowKey();

BOOL Timer();

void SpaceKey();

enum COLOR {RED=0,BROWN=1,TURQUOISE=2,GREEN=3,BLUE=4,PURPLE=5,YELLOW=6};

enum ORIENTATION { NORTH = 0, SOUTH = 1, EAST = 2, WEST = 3 };

// Overrides

public:

virtual BOOL OnNewDocument();

#ifdef SHARED_HANDLERS

virtual void InitializeSearchContent();

virtual void OnDrawThumbnail(CDC& dc, LPRECT lprcBounds);

#endif // SHARED_HANDLERS

#ifdef _DEBUG

virtual void AssertValid() const;

virtual void Dump(CDumpContext& dc) const;

#endif

protected:

// Generated message map functions

protected:

DECLARE_MESSAGE_MAP();

private:

void GameOver();

BOOL NewGame();

int AddScoreToList();

void DeleteFullRows();

BOOL IsRowFull(int iRow);

void FlashRow(int iFlashRow);

void DeleteRow(int iDeleteRow);

#ifdef SHARED_HANDLERS

// Helper function that sets search content for a Search Handler

void SetSearchContent(const CString& value);

#endif // SHARED_HANDLERS

};

这是实际的错误日志：

这是截图：

如您所见，m_colorGrid在函数上方的私有头中声明。
