CArchive串行化读取报错

高通量测序数据分析：RNA-seq 深度测序相关数据库与数据格式 SRA toolkit 一、NCBI 和EBI、DDBJ组成INSDC，数据内容相同所以找NCBI就行。（一）NCBI常用数据库 GenBank：遗传序列数据库，收集了所有公开的DNA序列及其注释 GEO (Gene Expression Omnibus) ：收集整理各种表达芯片数据，后来加入了甲基化、lncRNA、miRNA、CNV等其他芯片，还有高通量测序数据... 阅读详情

建了个对话框工程，新建了一个类CMydata
Mydata.h



struct IP_AND_INDEX

{

	CString strip[10];

	int index[10];

};



class CMydata : public CObject  

{

	CString fname;

	IP_AND_INDEX storeinfo;

	int nummap;

	DECLARE_SERIAL(CMydata)

public:

	CMydata(CString s1="",int num=0);

	void Serialize(CArchive& ar);

	int GetNummap();

	void SetFileName(CString str) {fname=str;}

	void GetFileName(CString &str) {str=fname;}

	void AddMap(CString str);

	virtual ~CMydata();



};

Mydata.cpp



IMPLEMENT_SERIAL(CMydata, CObject,2 )



CMydata::CMydata(CString s1,int num):fname(s1),nummap(num)

{

	for(int i=0;i<10;i++)

	{

		storeinfo.index [i]=0;

		storeinfo.strip [i]="";

	}

}



CMydata::~CMydata()

{



}



int CMydata::GetNummap ()

{

	return nummap;

}



void CMydata::AddMap (CString str)

{

	int num=GetNummap();

	if(num<10)

	{

		storeinfo.index [num]=num+1;

		storeinfo.strip [num]=str;

	}

	nummap++;

}

void CMydata::Serialize(CArchive& ar)

{

	CObject::Serialize(ar);

	if (ar.IsStoring())

	{

		// TODO: add storing code here

		ar<<fname;

		for(int i=0;i<nummap;i++)

			ar<<storeinfo.strip[i]<<storeinfo.index [i];

	}

	else

	{

		// TODO: add loading code here

		ar>>fname;

		for(int i=0;i<nummap;i++)

			ar>>storeinfo.strip[i]>>storeinfo.index [i];

	}

}

序列化写入函数（顺利执行）：



void CSerializeDemoDlg::OnButtonsave() 

{

	// TODO: Add your control notification handler code here

	CFile file;

	CFileException fe;

	if(!file.Open ("D:\\newpro\\map.dat",CFile::modeCreate|CFile::modeNoTruncate

						|CFile::modeWrite|CFile::shareExclusive,&fe))

	{

		fe.ReportError ();

		return;

	}

	file.SeekToEnd ();

	CArchive ar(&file,CArchive::store);

	

	CMydata *pd1=new CMydata;

	CMydata *pd2=new CMydata;

	CMydata *pd3=new CMydata;

	pd1->SetFileName ("d1.txt");

	pd1->AddMap ("10.0.188.11");

	pd2->SetFileName ("d2.mp3");

	pd2->AddMap ("10.0.188.22");

	pd2->AddMap ("10.0.188.222");

	pd3->SetFileName ("d3.jpeg");

	pd3->AddMap ("10.0.188.3");

	pd3->AddMap ("10.0.188.33");

	pd3->AddMap ("10.0.188.133");



	ar<<pd1<<pd2<<pd3;

	ar.Flush();

	ar.Close();

	file.Close ();

	delete pd1;

	delete pd2;

	delete pd3;

	MessageBox("store ok");

}

序列化读取函数（弹出对话框提示"D:\newpro\map.mat格式错")：



void CSerializeDemoDlg::OnButtonload() 

{

	// TODO: Add your control notification handler code here

	CFile file;

	CFileException fe;

	if(!file.Open ("D:\\newpro\\map.dat",CFile::modeRead,&fe))

	{

		fe.ReportError ();

		return;

	}

	CArchive ar(&file,CArchive::load);

	

	CMydata *pd1=new CMydata("",1);

	CMydata *pd2=new CMydata("",2);

	CMydata *pd3=new CMydata("",3);

	ar>>pd1>>pd2>>pd3;//这句无法执行了

	ar.Flush();

	ar.Close();

	file.Close ();
