C++ Standard的串行化问题

[piethy]

如何在C++ Standard中实现类的串行化，不依赖MFC或者其他系统相关的类库
请提供示例源代码

[bilbo0214]

//抽象接口定义
#if !defined SERIAL_H
#define SERIAL_H

class Serializer;
class DeSerializer;

class Serializable
{
public:
virtual void Serialize (Serializer & out) const = 0;
virtual void DeSerialize (DeSerializer & in) = 0;
};

//串行化实现，但是std::ios_base在Dev-C++4.9.7.0下提示未定义的错误,VC++6下可以编译

#if !defined SERSTREAM_H
#define SERSTREAM_H
#include <fstream>
using std::ios_base;

const long TruePattern = 0xfab1fab2;
const long FalsePattern = 0xbad1bad2;

class DeSerializer
{
private:
std::ifstream _stream;
public:
DeSerializer (std::string const & nameFile)
: _stream (nameFile.c_str (), ios_base::in | ios_base::binary)
{
if (!_stream.is_open ()) throw "²»ÄÜ´ò¿ªÎļþ";
};
long GetLong ();
double GetDouble ();
std::string GetString ();
bool GetBool ();
};

class Serializer
{
private:
std::ofstream _stream;
public:
Serializer (std::string const & nameFile)
: _stream (nameFile.c_str (), ios_base::out | ios_base::binary)
{
if (!_stream.is_open ()) throw "²»ÄÜ´ò¿ªÎļþ";
};
void PutLong (long l);

可能我的源文件字符集有问题，中文都变成"ÎļþдÈëÊ
了。

VC＋＋6这个编译器有时候让人头疼。
