Trouble calling a .DLL function from a Console Application - c

Question

I really need your help because I'm having many problems integrating one .DLL function into my Console Application.This .DLL consists on getting 2 chars(Char a and Char b)(Input) and adding them to one char.For example:
Char A=H
Char B=I
Output=HI
But here's the problem.When I compile the console application and when I run it,it says that the function hasn't been detected.And here's my question..Why the hell doesn't it find the function even though in the .def file I've listed the LIBRARY and the only exported function?Please help me.
THIS IS THE .DLL SOURCE
#include "stdafx.h"
char concatenazione(char a,char b)
{
return a+b;
}
**THIS IS THE .DEF FILE OF THE .DLL**
LIBRARY Concatenazione
EXPORTS
concatenazione #1
**And this is the dllmain.cpp**
#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;
}
**This is the Console Application partial source(For now it just includes the functions import part)**
#include <iostream>
#include <windows.h>
#include <stdio.h>
typedef int (__cdecl *MYPROC)(LPWSTR);
int main( void )
{
HINSTANCE hinstLib;
MYPROC ProcAdd;
BOOL fFreeResult, fRunTimeLinkSuccess = FALSE;
// Get a handle to the DLL module.
hinstLib = LoadLibrary(TEXT("C:\\ConcatenazioneDiAyoub.dll"));
// If the handle is valid, try to get the function address.
if (hinstLib != NULL)
{
ProcAdd = (MYPROC) GetProcAddress(hinstLib, "concatenazione");
// If the function address is valid, call the function.
if (NULL != ProcAdd)
{
fRunTimeLinkSuccess = TRUE;
(ProcAdd) (L"Message sent to the DLL function\n");
}
// Free the DLL module.
fFreeResult = FreeLibrary(hinstLib);
}
// If unable to call the DLL function, use an alternative.
if (! fRunTimeLinkSuccess)
printf("Message printed from executable\n");
return 0;
}
**The Console Applications runs fine but the output is "Message printed from executable".This means that the function hasn't been detected.**

Ok, I looked at what you have above and wondered where in your code you import the dll. I'm kind of new at this myself, so I found this article on how to do it.
If I understand correctly, in your console application you need to have a line like (assuming the name of your dll is "your.dll":
[DllImport("your.Dll")]
by the way, welcome to Stack Overflow, I noticed it is your first day! CHEERS!
