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 \n\r to \n (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
    {
    }
 }
