I work on my program, which I need for my bachelor work(C#/C++ interoperability) and I have problem with missing entry point in my code... I try create simply number generator, which will be genarated number in C++ class calling from C# ... At first I don't know how I pass a class, but then I found way how to do it on this page... Please help me fix it...
I added my code:
[C++]
#include <iostream>
#include <cstdlib>
#include <time.h>
using namespace std;
__declspec(dllexport) class Generator
{
private:
int zaciatok;
int koniec;
int pocetprvkov;
int *pole;
public:
Generator(){}
void Vytvor (int zaciatok, int koniec, int pocetprvkov)
{
srand((unsigned)time(0));
pole= new int [pocetprvkov];
}
void Napln()
{
for(int a=0; a<pocetprvkov; a++)
{
pole[a] = rand() % (koniec - zaciatok +1) + zaciatok;
}
}
void Vypis()
{
for(int a=0; a<pocetprvkov; a++)
cout << pole[a] << endl;
}
~Generator()
{
delete[] pole;
pole= 0;
}
};
extern "C"
{
__declspec(dllexport) Generator* Vytvor_Triedu() { return new Generator(); }
__declspec(dllexport) void Vytvor(Generator* prva) {prva->Vytvor(5,25,4); }
__declspec(dllexport) void Napln(Generator* prva) {prva->Napln(); }
__declspec(dllexport) void Vypis(Generator* prva) {prva->Vypis(); }
__declspec(dllexport) void Vymaz(Generator* prva) { delete prva; }
}
[C#]
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.InteropServices;
namespace GeneratorCsharp
{
class Program
{
[DllImport("DllTriedaGenerator.dll", CallingConvention = CallingConvention.Cdecl)]
public static extern IntPtr Vytvor_Triedu();
[DllImport("DllTriedaGenerator.dll", CallingConvention = CallingConvention.Cdecl)]
public static extern void Vytvor(IntPtr value);
[DllImport("DllTriedaGenerator.dll", CallingConvention = CallingConvention.Cdecl)]
public static extern void Napln(IntPtr value);
[DllImport("DllTriedaGenerator.dll", CallingConvention = CallingConvention.Cdecl)]
public static extern void Vypis(IntPtr value);
[DllImport("DllTriedaGenerator.dll", CallingConvention = CallingConvention.Cdecl)]
public static extern void Vymaz(IntPtr value);
static void Main(string[] args)
{
IntPtr trieda = Vytvor_Triedu();
Vytvor(trieda);
Napln(trieda);
Vypis(trieda);
Vymaz(trieda);
}
};
}
Thanks a lot!
好吧,您应该使用dumpbin,找到函数的乱码,然后在DllImport属性中添加EntryPoint =“ yourMangledName”。
