CArchive类读写

CFile* pFileName=new CFile("myfile.txt",CFile::modeCreate|CFile::modeWrite);CArchive SaveArchive(pFileName,CArchive::store|CArchive::bNoFlushOnDelete);//当删除指针时不强制刷新缓冲SaveArchive<<'H'<<'e'<<'l'<<'l'<<'o';//不支持字符串SaveArchive.Close();pFileName->Close();delete pFileName;

CArchive要先与一个CFile关联,CArchive可以看作是CFile的功能扩展版
