紫黄水晶的功效与作用:关于VC++编译出现错误的问题，请高手帮忙

class CStudentInfo : public CObject
{private:
CString strName;
CString strNo;
BOOL bMale;
CTime tBirth;
CString strSpecial;
DECLARE_SERIAL(CStudentInfo)

public:
CStudentInfo(){};
CStudentInfo(CString name,CString id,BOOL male,CTime birth,CString special);
void Serialize(CArchive &ar);
void Display(int y,CDC *pDC);
}

以上是"StudentInfo.h"文件

以下是"StudentInfo.cpp"文件
#include "stdafx.h"
#include "StudentInfo.h"
CStudentInfo::CStudentInfo(CString name,CString id,BOOL male,CTime birth,CString special)
{

//我在visual c++6.0建立了关于学生信息的可序列化结构，但在运行时在现在这个位置产生以下错误，
//不知道怎么改，还请各位高手帮忙
//E:\c\Student2\StudentInfo.cpp(4) : error C2533: 'CStudentInfo::CStudentInfo' : constructors not allowed a return type
