(重复帖子，忽略)如何从非托管dll调用函数 [英] (Duplicate Post, Ignore)how to call functions from unmanaged dll

问题描述

任何人都可以帮我吗?
我正在尝试调用一个函数say getdevice();
出现在我的非托管dll中. dll中的函数具有参数
getdevice(char ** pDeviceList，int * pDeviceCount，unsigned longulFlags)
实际上我正在使用c#并在c#中进行编码，并且我的dll在c ++中，而我的应用程序的整个编码也在c ++中，但是我想导入我的dll并调用我的函数，我有导入我的dll的代码，但不知道如何调用函数以及我必须从main()传递的参数
我不知道用c#编码时调用dll中存在的函数时传递参数的正确数据类型和正确方法.

在c#中是否有可能从main()调用dll中存在的函数时将指针作为参数传递? 因为从上面可以看出，function( getdevice())带有poeners作为参数.
在c#中，是否有任何方法可以通过函数传递指针以从main()调用函数

hi ,
Please can anyone help me ?
i m trying to call a function say getdevice();
which is present in my unmanaged dll. the function in dll has parameters say
getdevice(char **pDeviceList,int *pDeviceCount, unsigned longulFlags)
actually i m using c# and doing coding in c# as well and my dll is in c++ and whole coding of my application is also in c++ but i want to import my dll and call my functions , I have code to import my dll but dont know how to call the function and what parametrs i have to pass from main()
I dont know while coding in c# the proper datatypes and proper way for the parameters to pass while calling my function present in dll .

Is it possible in c# to pass pointers as parametrs while calling a function present in dll from main()
because as it can be seen above function(getdevice()) has poniters as parameters.
In c# Is there any way to pass pointers through a function to call a function from main()
