WDF_FILE_INFORMATION_CLASS列舉 （wdffileobject.h）
[警告： UMDF 2 是最新版本的 UMDF，並取代 UMDF 1。 所有新的UMDF驅動程式都應該使用UMDF 2撰寫。 未將新功能新增至 UMDF 1，而且較新版本的 Windows 10 上對 UMDF 1 的支援有限。 通用 Windows 驅動程式必須使用 UMDF 2。 如需詳細資訊，請參閱 開始使用 UMDF。]
WDF_FILE_INFORMATION_CLASS 列舉會識別驅動程式可取得或設定的檔案信息類型。

備註
WDF_FILE_INFORMATION_CLASS 列舉會作為輸入值，以 IWDFIoRequest2：：GetQueryInformationParameters，以及作為 IWDFIoRequest2：：GetSetInformationParameters的輸出值。
對於 WDF_FILE_INFORMATION_CLASS 列舉定義的大部分值，wdm.h 或 ntifs.h 頭文件會定義驅動程式在取得或設定檔案資訊時可以使用的FILE_XXXX_INFORMATION具名結構。
如需列舉值和相關結構的詳細資訊，請參閱 ZwQueryInformationFile ZwSetInformationFileFileInformationClass 參數的描述。
