Unrsolved token ERROR VC++

[Jazi]

Hi All,

Can any one tell me how to resolve the following issue;
I have the following function

hello.cpp
#include "stdafx.h"
#include <stdlib.h>
#include <vcclr.h>
#include <string>
namespace Wrapper
{

String^ Wrapper_Class:: sayHello(void){
String^ str="Hello";
return str;
}
}

hello.h
#pragma once


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

using namespace System::Runtime ::InteropServic es;
using namespace System;
using namespace std;

String^ Wrapper_Class:: sayHello(void)


Here is the ERROR message I keep getting
error LNK2020: unresolved token (06000012) Wrapper.SinFold _Wrapper_Class: :sayHello

Can any one tell me what am I doing wrong? or how to resolve it?

Thank you...

This looks like C#.

I am moving this to the .NET forum.
