[StructLayoutAttribute(LayoutKind.Sequential)] public struct NET_DVR_HDCFG { public uint dwSize; public uint dwHDCount;/*硬盘数(不可设置)*/ [MarshalAsAttribute(UnmanagedType.ByValArray, SizeConst = MAX_DISKNUM_V30, ArraySubType = UnmanagedType.Struct)] public NET_DVR_SINGLE_HD[] struHDInfo;//硬盘相关操作都需要重启才能生效； }

想解析这个
NET_DVR_SINGLE_HD需要怎么写啊？
