C# Class ICSharpCode.SharpZipLib.Zip.ZipInputStream

This is an InflaterInputStream that reads the files baseInputStream an zip archive one after another. It has a special method to get the zip entry of the next file. The zip entry contains information about the file name size, compressed size, Crc, etc. It includes support for Stored and Deflated entries.

Méthodes publiques

Méthode	Description
CloseEntry ( ) : void	Closes the current zip entry and moves to the next one.
GetNextEntry ( ) : ZipEntry	Advances to the next entry in the archive If the previous entry is still open CloseEntry is called.
Read ( byte buffer, int offset, int count ) : int	Read a block of bytes from the stream. Zero bytes read means end of stream.
ReadByte ( ) : int	Reads a byte from the current zip entry.
ZipInputStream ( Stream baseInputStream ) : System	Creates a new Zip input stream, for reading a zip archive.
ZipInputStream ( Stream baseInputStream, int bufferSize ) : System	Creates a new Zip input stream, for reading a zip archive.

BodyRead ( byte buffer, int offset, int count ) : int	Reads a block of bytes from the current zip entry.
CompleteCloseEntry ( bool testCrc ) : void	Complete cleanup as the final part of closing.
InitialRead ( byte destination, int offset, int count ) : int	Perform the initial read on an entry which may include reading encryption headers and setting up inflation.
ReadDataDescriptor ( ) : void	Read data descriptor at the end of compressed data.
ReadingNotAvailable ( byte destination, int offset, int count ) : int	Handle attempts to read by throwing an InvalidOperationException.
ReadingNotSupported ( byte destination, int offset, int count ) : int	Handle attempts to read from this entry by throwing an exception

Method Details

CloseEntry() public méthode

Closes the current zip entry and moves to the next one.

/// The stream is closed /// /// The Zip stream ends early ///

public CloseEntry ( ) : void
Résultat	void

Dispose() protected méthode

Closes the zip input stream

protected Dispose ( bool disposing ) : void
disposing	bool
Résultat	void

GetNextEntry() public méthode

Advances to the next entry in the archive

If the previous entry is still open CloseEntry is called.

/// Input stream is closed /// /// Password is not set, password is invalid, compression method is invalid, /// version required to extract is not supported ///

public GetNextEntry ( ) : ZipEntry
Résultat	ZipEntry

Read() public méthode

Zero bytes read means end of stream.

public Read ( byte buffer, int offset, int count ) : int
buffer	byte	The destination for the bytes.
offset	int	The index to start storing data.
count	int	The number of bytes to attempt to read.
Résultat	int

ReadByte() public méthode

Reads a byte from the current zip entry.

public ReadByte ( ) : int
Résultat	int
