No copy constructor available for class怎么解决呢

Question

 struct stuFileData
{ 
    CString csIndex;    
    CString csTime;     
    CString csFunction;
    CString csLen;  
    CString csData;     
    CString csOneLine;


    //0为Normal
    //1000为随机cmd 
    //1001为连接手机中断
    int     CmdFlag;    

    stuFileData(CString csTmp)
    {
        if (csTmp.GetLength()>66)
        {
            //略
        }
        else
        {
            //略
        }
    }
    stuFileData()
    {
            //略
    }

    stuFileData(const stuFileData &p)
    {

        csIndex = p.csIndex;
        csTime  = p.csTime;
        csFunction = p.csFunction;
        csLen = p.csLen;
        csData = p.csData;
        csOneLine = p.csOneLine;
        CmdFlag =  p.CmdFlag;
    }
}; 

typedef  CArray<stuFileData, stuFileData> DataPacketCArray;

DataPacketCArray b;
//初始化b，这里不写了

DataPacketCArray a=b;

最后这个时，报

 No copy constructor available for class 'CArray<struct stuFileData,struct stuFileData>'

怎么解决呢

Answer 1

说的很清楚，定义一个拷贝构造函数
public: stuBushFileData(stuBushFileData & data)
{
... //在这里赋值
}
