为什么char数组成员无法通过boost序列化？ [英] why char array member can't be serialized by boost?

问题描述

以下是简单的boost序列化代码，但ClassA.name成员无法序列化和反序列化，任何人都可以帮助我吗？

Following is simple boost serialization code, but ClassA.name member can't be serialized and deserialized, anyone can help me?

class ClassA
{
public:
	int number;
	char name[64];
};

template<class archive="">
void serialize(Archive & ar, ClassA& g, const unsigned int version)
{
	ar & g.number;
	ar & g.name;
};

int _tmain(int argc, _TCHAR* argv[])
{
	ClassA obj1;
	obj1.number = 21;
	sprintf_s(obj1.name, 64, "%s", "Hello World!");

	std::ofstream ofs("D:\\efg.txt", std::ios::out);
	if (!ofs.fail())  
	{  
		boost::archive::text_oarchive oa(ofs);
		oa << obj1;
		ofs.close();
	}

	ClassA obj2;
	std::ifstream ifs("D:\\efg.txt");
	if (!ifs.fail())  
	{  
		boost::archive::text_iarchive ia(ifs);
		ia >> obj2;

		ifs.close();
	}

	return 0;
}</class>

推荐答案

据我所知，boost序列化无法序列化char数组。您应该使用std :: string来保存字符串并将其序列化。



如果必须使用char数组，可以将其转换为序列化目的如此处所述[ ^ ]

For all i know boost serialization can't serialize a char array. You should be using std::string to hold your strings and just serialize that.

If you must use a char array, you can convert it for the purpose of serialization as described here[^]
