Converting c++ structs to c#, how to do?

Hello guys, I need to use a C++ Dll at C#, so I figure that I need to re-write some structs and enums. I have this code at my header file in C++.

#pragma mark STRUCTURES

    typedef void* QCam_Handle;

    typedef struct _TAG_CAM_SETTINGS_ID_GUID_STRUCT_
    {


        uint32_t f1;
        uint16_t f2;
        uint16_t f3;
        uint8_t  f4[8];
    }QCam_settings_id, *pQCam_settings_id;

    // QCam_Settings is obsolete. Use QCam_SettingsEx in conjunction with QCam_CreateCameraSettingsStruct,
    // QCam_Err QCam_InitializeCameraSettings and QCam_ReleaseCameraSettings
    typedef struct
    {
        unsigned long size;
        unsigned long _private_data[ 64 ];
    }
    QCam_Settings;

    typedef struct
    {
        unsigned long       size;                   // Filled by the initialization routine
        QCam_settings_id    _pSettingsID;           // pointer to the camera settings ID
        unsigned long       *_private_data;         // Pointer to a camera settings array
    }
    QCam_SettingsEx, *pQCam_SettingsEx;

    typedef struct
    {
        unsigned long       cameraId;           // Camera ID (ex: 0 for first camera, 1 for second)
        unsigned long       cameraType;         // Camera Model
        unsigned long       uniqueId;           // Unique ID for the camera
        unsigned long       isOpen;             // 1 if already open, 0 if closed

        unsigned long       _reserved[ 10 ];
    }
    QCam_CamListItem;

Is there any way to do that? I'm starting at this, some help would be wonderful
