用CArchive如何来序列化自定义的结构体？？急！！

[rabbit_zizhu]

自定义的结构图如下：

struct A{
CString str;
};
typedef struct B
{
struct A a;
CString s[3];
};

想网络传输结构体B，该怎么序列化呢，最好举个例子

例子

struct   A{   
  int   a   ;   
  float   b;   
  friend   CArchive   &   operator   <<(CArchive   &   arc,A   &data);   
  friend   CArchive   &   operator   >>(CArchive   &   arc,A   &data);   
  }   
    
  CArchive   &   operator   <<(CArchive   &   arc,A   &data)   
  {   
      arc<<a<<b;   
  return   arc;   
  }   
  CArchive   &   operator   >>(CArchive   &   arc,A   &data)   
  {   
  arc>>a>>b   
  return   arc;   
  }

将结果转换成字节数据,先把数据大小写入,再写入字节内容.也可以将数据构建成CObject类的形式.
比如:
struct A{
CString str;
};
int nCount = A.str.GetLength();
BYTE *pData = new BYTE[nCount+1];
memcpy(pData,A.str.GetBuffer(nCount),nCount);
CFile f;
char buf[512];
if( !f.Open( "C:\test.dat", CFile::modeCreate | CFile::modeWrite ) ) {
#ifdef _DEBUG
afxDump << "Unable to open file" << "\n";
exit( 1 );
#endif
}

CArchive cf(f,CArchive::store);//写入
cf<<nByteCount;
for(int i=0;i<nCount;i++)
cf<<pData[i];
