使用

main.cpp

#include <iostream>
#include <CustomVariantValue.h>


using namespace std;




int main(int argc, char *argv[])
{

    CustomVariantValue vInt = 1;
    CustomVariantValue vBool = true;

    int rvInt = vInt;
    cout<<rvInt<<endl;

    if(vInt == vBool)
        cout<<"vInt == vBool"<<endl;
    else
        cout<<"vInt!=vBool"<<endl;
    return 0;
}
