CfbReader

Vue de l’ensemble

‘CfbReader’ est un parzer de bas niveau, seulement lisible pour les fichiers binaires Compound File. Construisez-le via ‘FromFile’ ou ‘FromStream’, puis navigez sur l’arbre de directoire avec ‘IterStorages’, ‘IterStreams’, `Itchildren’ et ’ FindChildByName’. Utilisez ‘GetStreumData’ pour lire des bytes crus d’un courant appelé. Implémentations ‘IDisposable’; utilisez toujours dans un bloc ‘utiliser’ afin de libérer les manuels de fichier.

constructeurs

Signature	Description
`CfbReader(data: byte[])`	Creates a new `CfbReader` with the specified parameters.

méthodes

Signature	Description
`FromFile(path: string)`	Opens the CFB file at `path` and returns a new `CfbReader`.
`FromStream(stream: Stream)`	Reads a CFB file from `stream` and returns a new `CfbReader`.
`Dispose()`	Releases any file handle or stream held by this reader.
`GetEntry(streamId: uint)`	Returns the `DirectoryEntry` for the given `streamId`.
`GetStreamData(streamId: uint)`	Returns the raw byte content of the stream identified by `streamId`.
`IterStorages()`	Yields all storage-type directory entries in tree order.
`IterStreams()`	Yields all stream-type directory entries in tree order.
`IterChildren(storageStreamId: uint)`	Yields direct child entries of the storage identified by `storageStreamId`.
`IterTree(startStreamId: uint)`	Yields all entries in the subtree rooted at `startStreamId` (depth-first).
`FindChildByName(storageStreamId: uint, name: string)`	Returns the stream ID of the direct child of `storageStreamId` whose name equals `name`, or null if not found.
`ResolvePath(names: IEnumerable<string>, startStreamId: uint)`	Walks a sequence of `names` starting from `startStreamId` and returns the stream ID of the final entry.
