新手求教:在DriverStudio生新的驱动框架中ZwQueryDirectoryFile函数时报连接错误,而在C写的框架中就没问题

定义的原码如下:
extern NTSYSAPI NTSTATUS NTAPI ZwQueryDirectoryFile(
             IN HANDLE hFile,
             IN HANDLE hEvent OPTIONAL,
             IN PIO_APC_ROUTINE IoApcRoutine OPTIONAL,
             IN PVOID IoApcContext OPTIONAL,
             OUT PIO_STATUS_BLOCK pIoStatusBlock,
             OUT PVOID FileInformationBuffer,
             IN ULONG FileInformationBufferLength,
             IN FILE_INFORMATION_CLASS FileInfoClass,
             IN BOOLEAN bReturnOnlyOneEntry,
             IN PUNICODE_STRING PathMask OPTIONAL,
             IN BOOLEAN bRestartQuery);

引用如下:
NTSTATUS Filehide::DriverEntry(PUNICODE_STRING RegistryPath)
{
...
RealZwQueryDirectoryFile=(REALZWQUERYDIRECTORYFILE)(SYSTEMSERVICE(ZwQueryDirectoryFile));
...
}
报错为:
ilehide.obj : error LNK2019: unresolved external symbol \"__declspec(dllimport) long __stdcall ZwQueryDirectoryFile(void *,void *,void (__stdcall*)(void *,struct _IO_STATUS_BLOCK *,unsigned long),void *,struct _IO_STATUS_BLOCK *,void *,unsigned long
,enum _FILE_INFORMATION_CLASS,unsigned char,struct _UNICODE_STRING *,unsigned char)\" (__imp_?ZwQueryDirectoryFile@@YGJPAX0P6GX0PAU_IO_STATUS_BLOCK@@K@Z010KW4_FILE_INFORMATION_CLASS@@EPAU_UNICODE_STRING@@E@Z) referenced in function \"public: virtual l

请高人指点,而在C写的框架中如此引用就没问题

很明显，你忘了加extern \"C\"

原来是加了extern \"C\"的,不行,现在又试了一下也是不行.
我没有用DS了,程序到是都编译成功,可没有INI文件,也没有GUID,怎么安装和调试了,新的问题又出来了
