need help with exporting DLL with a class in it

//this is my DLL code

Code:

#include "stdafx.h"
#include <stdio.h>

extern "C" __declspec(dllexport)void test();

BOOL APIENTRY DllMain( HANDLE hModule, 
                       DWORD  ul_reason_for_call, 
                       LPVOID lpReserved
					 )
{
    return TRUE;
}

class __declspec(dllexport) MyClass
{
int myInt;
};

extern "C" __declspec (dllexport) MyClass;

//this compiles fine , i copy dll.dll and dll.lib to the cpp where main is ...
//this is the main cpp file

Code:

#include <iostream.h>
#pragma comment(lib , "dll.lib")

extern "C" __declspec (dllexport) MyClass;




int main()
{

   MyClass My; //but i am unable todo this ???????????

    return 0;
}

you do not expect to export class as a C feature?

PS.
#include <iostream.h> - it is outdated
use <iostream>

can anone help?,

Maybe an example will help you.
