QuestionVC++ DLL throws error when call it from C#[EntryPointNotFound] Pin

Here i created in DLL project in vc++ 2008. Following are two code files lib.h and lib.cpp.
lib.h
C++
#include "stdafx.h";

    class __declspec(dllexport) test
    {
    public:
        test();
        static void  hello();
        static void  hello1();
    };

    class __declspec(dllexport) test1
    {
    public:
        test1();
        void  hello_test1();
        void  hello1_test1();

    };

lib.cpp
C++
#include "stdafx.h"
   #include "lib.h"
   #include <stdio.h>

   void test::hello()
   {
       printf("Hello");
   }

   void test::hello1()
   {
       printf("Hello1");
   }

   void test1::hello_test1()
   {
       printf("Hello_test1");
   }

   void test1::hello1_test1()
   {
       printf("Hello1_test1");
   }

stdafx.h
C++
#include "targetver.h"
#define WIN32_LEAN_AND_MEAN 
// Windows Header Files:
#include <windows.h>

dllMain.cpp
C++
#include "stdafx.h"

BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
                     )
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
    case DLL_THREAD_ATTACH:
    case DLL_THREAD_DETACH:
    case DLL_PROCESS_DETACH:
        break;
    }
    return TRUE;
}

I have written C# code to call the method of test and test1 classes:
consoleApp
C#
 [DllImport("lib.dll" )]
    public static extern void hello();

    [DllImport("lib.dll")]
    public static extern void hello1();

    [DllImport("lib.dll")]
    public static extern void hello_test1();

    [DllImport("lib.dll")]
    public static extern void hello1_test1();

 static void Main()
{ 
        hello();
        hello1();
        hello_test1();
        hello1_test1();
        Console.ReadKey();
    }

when i run above code i have got following error: EntryPointNotFoundException: Unable to find an entry point named 'hello' in DLL 'lib.dll' 1****<-Click 1 for image
I know about how to call function only(without using Class) of vc++ DLL from C# but i don't know how to call method of any class and how to code that in proper way in vc++.

I know somewhere is mistake in my above code, please experts guide me about my mistake because i tried all from my side.

If anyone has full example like above then suggest me.

Thanks in advance..
