我试图从我的C#程序中的C ++ DLL文件中调用某些函数。但是当涉及到指针时,我陷入了困境。有人可以指出我正确的方向吗?这是带有目标函数的C ++头文件:#pragma once#ifdef STCL_DEVICES_DLL#define STCL_DEVICES_EXPORT extern "C" _declspec(dllexport) #else#define STCL_DEVICES_EXPORT extern "C" _declspec(dllimport)#endifenum SD_ERR{ SD_ERR_OK = 0, SD_ERR_FAIL, SD_ERR_DLL_NOT_OPEN, SD_ERR_INVALID_DEVICE, //device with such index doesn't exist SD_ERR_FRAME_NOT_SENT,};#pragma pack (1)struct LaserPoint{ WORD x; WORD y; byte colors[6];};struct DeviceInfo{ DWORD maxScanrate; DWORD minScanrate; DWORD maxNumOfPoints; char type[32];};/////////////////////////////////////////////////////////////////////////////Must be called when starting to use//////////////////////////////////////////////////////////////////////////STCL_DEVICES_EXPORT int OpenDll();/////////////////////////////////////////////////////////////////////////////Search for .NET devices (Moncha.NET now)///Must be called after OpenDll, but before CreateDeviceList!///In pNumOfFoundDevs can return number of found devices (optional)//////////////////////////////////////////////////////////////////////////STCL_DEVICES_EXPORT int SearchForNETDevices(DWORD* pNumOfFoundDevs);/////////////////////////////////////////////////////////////////////////////All devices will be closed and all resources deleted//////////////////////////////////////////////////////////////////////////STCL_DEVICES_EXPORT void CloseDll();此外,如何处理其他函数参数,例如WCHAR **和structsDeviceInfo和LaserPoint?
