## Remarks

若要创建实现 `IDStorageFileX` 接口的对象，请调用 [IDStorageFactoryX::OpenFile](/reference/system/dstorage/interfaces/IDStorageFactoryX/methods/idstoragefactoryx_openfile) 方法。这与在 Win32 API 接口中使用 `CreateFile` 类似。

有关详细信息，请参阅 [DirectStorage 概述](/build/console-features/storage/directstorage/directstorage-overview) 中的“API overview”一节。

## Requirements

**头文件：** dstorage\_xs.h
