boost binary 序列化

在用boost 二进制序列化类的时候，需要注意动态调用文件打开标志std::ios::binary： 


The flag std::ios::binary is required only in Windows, where the default mode (ascii) would translate to (and vice versa), thus corrupting any data that is not textual. 

#include <boost/serialization/string.hpp>
#include "boost/archive/binary_oarchive.hpp"
#include "boost/archive/binary_iarchive.hpp"
#include "boost/iostreams/stream.hpp"
#include <boost/serialization/version.hpp>

typedef struct tagWorkStruct
{
    string groundTruthFile;
    string jpegFile;
    int workId;
}WorkStruct;

template<class Archive>
void serialize(Archive &ar, AddNewCardWorkStruct &g, const unsigned int version)
{
    ar & g.groundTruthFile;
    ar & g.jpegFile;
    ar & g.workId;
}


//写入文件
string fileName = "test.dat";
ofstream os(fileName.c_str(), std::ios::binary);
if (!os.fail())
{
    try
    {
        WorkStruct tempStruct;
        boost::archive::binary_oarchive oa(os);
        oa << tempSturct;
    }
    catch(...)
    {
    }
}


//读取文件
ifstream is(dataFileName.c_str(), std::ios::binary);
if (!is.fail())
{
   try
   {
    WorkStruct tempStruct;
    boost::archive::binary_iarchive ia(is);
    ia >> tempStruct;
   }
   catch (...)//boost::archive::archive_exception
   {
   }
}
