将C++ 迁移到 C# 的尝试问题

[szaibo]

我想把一下 C++ 实现的方法 转为C# 实现 请问可以做到吗?

主要想取出 硬件ID

LRESULT CHWDetectDlg::OnMyDeviceChange(WPARAM wParam, LPARAM lParam)
{
if ( DBT_DEVICEARRIVAL == wParam || DBT_DEVICEREMOVECOMPLETE == wParam ) {
PDEV_BROADCAST_HDR pHdr = (PDEV_BROADCAST_HDR)lParam;
PDEV_BROADCAST_DEVICEINTERFACE pDevInf;
PDEV_BROADCAST_HANDLE pDevHnd;
PDEV_BROADCAST_OEM pDevOem;
PDEV_BROADCAST_PORT pDevPort;
PDEV_BROADCAST_VOLUME pDevVolume;
switch( pHdr->dbch_devicetype ) {
case DBT_DEVTYP_DEVICEINTERFACE:
pDevInf = (PDEV_BROADCAST_DEVICEINTERFACE)pHdr;
UpdateDevice(pDevInf, wParam);
break;

case DBT_DEVTYP_HANDLE:
pDevHnd = (PDEV_BROADCAST_HANDLE)pHdr;
break;

case DBT_DEVTYP_OEM:
pDevOem = (PDEV_BROADCAST_OEM)pHdr;
break;

case DBT_DEVTYP_PORT:
pDevPort = (PDEV_BROADCAST_PORT)pHdr;
break;

case DBT_DEVTYP_VOLUME:
pDevVolume = (PDEV_BROADCAST_VOLUME)pHdr;
break;
}
}
return 0;
}

typedef DEV_BROADCAST_HDR DBTFAR *PDEV_BROADCAST_HDR;

typedef struct _DEV_BROADCAST_HDR DEV_BROADCAST_HDR;

struct _DEV_BROADCAST_HDR { /* */
DWORD dbch_size;
DWORD dbch_devicetype;
DWORD dbch_reserved;
};

可以，你必须将你的类拆成函数封装成dll，
然后在c#中引用。

(PDEV_BROADCAST_HDR)lParam; 请问是什么意思啊
typedef DEV_BROADCAST_HDR DBTFAR *PDEV_BROADCAST_HDR;

typedef struct _DEV_BROADCAST_HDR DEV_BROADCAST_HDR;

struct _DEV_BROADCAST_HDR { /* */
DWORD dbch_size;
DWORD dbch_devicetype;
DWORD dbch_reserved;
};
转后转出来是一下结果了
