Question

如何使用electric_potential类型和double来序列化地图？在我的代码中，我放了这些标题：

#include <boost/serialization/complex.hpp>
#include <boost/serialization/map.hpp>
#include <boost/units/physical_dimensions/electric_potential.hpp>

template<class Archive, class T> 
static void serialize( Archive & ar, T & t, const unsigned int file_version ){ 
  t.serialize(ar, file_version); 
}
extern "C++" class Data_substation_AC2 : public Data_OG
{
private:
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive & ar, const unsigned int version) {
    ar & BOOST_SERIALIZATION_BASE_OBJECT_NVP(Data_OG);
    ar & BOOST_SERIALIZATION_NVP(_primary_voltage);
    ar & BOOST_SERIALIZATION_NVP(_secondary_voltage);
    ar & BOOST_SERIALIZATION_NVP(_impedance1);
    ar & BOOST_SERIALIZATION_NVP(_impedance2);
    ar & BOOST_SERIALIZATION_NVP(_location);
}
std::string                                                   _name;        
bu::quantity<si::electric_potential>                          _primary_voltage;
bu::quantity<si::electric_potential>                          _secondary_voltage;
bu::quantity<si::resistance, std::complex<double>>            _impedance1;
bu::quantity<si::resistance, std::complex<double>>            _impedance2;
Data_location                                                 _location;

我尝试了所有标题，但仍然有这个错误：

error C2039: 'serialize' : is not a member of 'boost::units::
quantity<boost::units::si::electric_potential,double>'

我正在寻找解决这个问题的最简单方法。谢谢 in this picture the code when i use the type electrical_potential

我没看到问题可能是什么。你不能展示一个完整的，独立的样本，这意味着我无法帮助你实现这个问题，除非通过展示我的所作所为来实现它：
