What's the best way to output the public contents of an object to a human-readable file? I'm looking for a way to do this that would not require me to know of all the members of the class, but rather use the compiler to tell me what members exist, and what their names are. There have to be macros or something like that, right?

Contrived example: 

```
class Container
{
public:
    Container::Container() {/*initialize members*/};
    int stuff; 
    int otherStuff;
};
Container myCollection;

```

I would like to be able to do something to see output along the lines of "myCollection: stuff = value, otherStuff = value". 
But then if another member is added to Container, 

```
class Container
{
public:
    Container::Container() {/*initialize members*/};
    int stuff;
    string evenMoreStuff;
    int otherStuff;
};
Container myCollection;
```

This time, the output of this snapshot would be "myCollection: stuff = value, evenMoreStuff=value, otherStuff = value"

Is there a macro that would help me accomplish this? Is this even possible? (Also, I can't modify the Container class.)
Another note: I'm most interested about a potential macros in VS, but other solutions are welcome too.
