    cout<<"文件导入成功,导入"<<(Size)<<"条记录!";
    cout<<"请输入(1,2,3,4,5,6,7,8)选择(退出按0):";
}

这是我的StructNode
struct DataNode
{
    string SNumber;
    string SName;
    string Sex;
    string Date;
    string Political;
    string Link;
    string Address;
};

不可以 read(node,sizeof(DataNode),1,file)，这太扯蛋了

什么意思，能说清楚点吗？
