open改为ofs.open(name, std::ios::out | std::ios::binary); 就对了! 原因应该是ofstream打开文件时默认是文本格式吧。。。 void open( const char *_Filename, ios_base::openmode_Mode= ios_base::out, int_Prot= (int)ios_base::_Openprot ...

类模板 basic_ofstream 实现文件上基于流的高层输出操作。它将 std::basic_ostream 的高层接口赋予基于文件的流缓冲( std::basic_filebuf)。 std::basic_ofstream 典型实现只保有一个非导出成员: std::basic_filebuf<CharT, Traits> 的实例。 继承图 亦对常用字符类型定义二个特化: ...
