解决VC++编译报错error C2248的方案

class COptRect : public CObject
{

public:
 COptRect();
 virtual ~COptRect();
 // 操作的起始范围
 CRect m_OptStartRect;
 // 操作的结束范围
 CRect m_OptEndRect;
 // 操作的目标界面
 int m_OptDesSurface;

 COptRect& operator = (COptRect & src);

};

COptRect::COptRect()
 : m_OptDesSurface(0)
{
}

COptRect::~COptRect()
{
}

COptRect& COptRect::operator = (COptRect & src)
{
 this->m_OptDesSurface = src.m_OptDesSurface;
 this->m_OptEndRect = src.m_OptEndRect;
 this->m_OptStartRect = src.m_OptStartRect;
 return *this;
}

CArray<COptRect, COptRect&> optArray;

// 向界面添加一个操作区域
void CSurface::AddOptRect(CRect Start, CRect End, int DesID)
{
 COptRect ort;
 ort.m_OptStartRect = Start;
 ort.m_OptEndRect = End;
 ort.m_OptDesSurface = DesID;
 optArray.Add(ort);
}
