Main.cpp的

// create and open a character archive for output
    std::ofstream ofs("filename");

     boost::archive::text_oarchive oa(ofs);
        // write class instance to archive
        oa << Monopoly;
        // archive and stream closed when destructors are called

        Game newg;
         // create and open an archive for input
        std::ifstream ifs("filename");
        boost::archive::text_iarchive ia(ifs);
        // read class state from archive
        ia >> newg;
        // archive and stream closed when destructors are called

基本上它在序列化时没有问题，但是当反序列化时会引发错误。

由于

Answer 1

尝试

std::ofstream ofs("filename");
boost::archive::text_oarchive oa(ofs);
oa << Monopoly;

ofs.close(); // <= HERE

Game newg;
std::ifstream ifs("filename");
boost::archive::text_iarchive ia(ifs);
ia >> newg;

Answer 2

当你写下来时，答案就在你的问题中：

   oa << Monopoly;
    // archive and stream closed when destructors are called <<<<<<<<<<<<<<<<<<<

当您尝试打开文件进行阅读时，文件未关闭。

在阅读测试之前添加ofs.close()。或者更好的是，将测试的每个部分放在一个{}块中，并在块中声明相关的流变量，这样在离开块范围时归档和流就会被销毁。

Answer 3

我有这个确切的问题。当您尝试反序列化具有未初始化成员变量的先前序列化类时，Boost序列化会出现此错误。对于您的问题，您将必须将类中的每个变量都初始化为某个合理的值。

换句话说

\0

应该是

...
int cost;
int mortagecost;
int house1cost;
int house2cost;
...

或者您可以初始化类每个实例的每个变量。我希望这会有所帮助。

PS：您没有初始化STL容器。
