在C#中调用VC ++ DLL函数

问题描述

我有一个VC ++ dll，我想用它从c#调用.
我有一个用C ++定义的类.

Hi,

I have a VC++ dll which I want to use to call from c#.
I have a class defined in C++.

/* -----------------------*/

class PropertyPageDlg : public CPropertyPage

{

   public:

      __declspec(dllexport) void glen();
 };

extern "C"

{

     __declspec(dllexport) void CZippyPlus_PropertyPageDlg::glen()

   {

      printf("\n Hi Hello World ");
      getchar();

    }
}

我想在c#中调用此OnBtnDisconnect函数.

这是我所做的.

I want to call this OnBtnDisconnect function in c#.

Here is what I have done .

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;


namespace C_sharp
{
    class Program
    {
       [DllImport("PropertySheetApp.dll")]
         public static extern void glen();
        static void Main(string[] args)
        {
            Console.WriteLine("This is C# program");
            glen();

        }
     }
}

运行c#程序时出现以下错误.

C_sharp.exe中发生了类型为"System.EntryPointNotFoundException"的未处理的异常

附加信息:在DLL"PropertySheetApp.dll"中找不到名为"glen"的入口点.

感谢您对此提供的任何帮助.

谢谢

Additional information: Unable to find an entry point named ''glen'' in DLL ''PropertySheetApp.dll''.
