如何将mfc dll API转换为c＃ [英] How to convert mfc dll API to c#

问题描述

您好b $ b

我想调用一个用mfc编写的API



这是API



BOOL __stdcall SearchMAC（LPCTSTR strIP，CString& strMac）



我试图声明如下API

 [DllImport（  DllEx.dll，EntryPoint =   SearchMAC，CharSet = CharSet.Unicode ）] 
  public   static   extern  不安全  bool  SearchMAC（ string  strIP，  string  MAC）; 

并调用下面的API

  string  mac =   02ABCDEFGIJ; 
  bool  x = DLL.SearchMAC（  192.168.1.100，mac）; 

但它总是返回false。



请帮我读一下MAC地址，因为我是c＃的新手。



谢谢

解决方案

如果您只想获取MAC地址，我建议您不要使用MFC dll并使用更新的方法。

Hi
I would like to call an API which is written in mfc

This is the API

BOOL __stdcall SearchMAC(LPCTSTR strIP,CString &strMac)

I tried to declare the API like below

[DllImport("DllEx.dll", EntryPoint = "SearchMAC", CharSet = CharSet.Unicode)]
        public static extern unsafe bool SearchMAC(string strIP,  string MAC);

and called the API like below

string mac = "02ABCDEFGIJ";
                bool x = DLL.SearchMAC("192.168.1.100", mac);

But it it always returns false.

Kindly help me to read the MAC address as I am new to c#.

Thank you

解决方案

If all you want is to get the MAC address I would suggest not trying to use the MFC dll and to use the updated approach.
