C ++ DLL экспорт не определен ⇐ C++

[Anonymous]

Я пытаюсь создать C ++ DLL, который я могу импортировать в C#, но мой код не компилируется. < /p>

Вот код: < /p>

//main.cpp
#include "C:\Users\Mihai\Desktop\body.cpp"
#include "C:\Users\Mihai\Desktop\header.h"

extern "C"_declspec(dllexport) int sumTwo(int var_x, int var_y)
{
myClass MC(var_x, var_y);
return MC.sumX_Y();

}

//body.cpp
#pragma once
#include "Header.h"

myClass::myClass(int var_x, int var_y)
{
x = var_x;
y = var_y;
}

int myClass::sumX_Y()
{
return x + y;
}

//Header.h
#pragma once

class myClass
{
public:
myClass(int var_x, int var_y);
int sumX_Y();
private:
int x;
int y;

};
