Открытые методы

Метод	Описание
DeflaterOutputStream ( Stream baseOutputStream ) : System	Creates a new DeflaterOutputStream with a default Deflater and default buffer size.
DeflaterOutputStream ( Stream baseOutputStream, Deflater deflater ) : System	Creates a new DeflaterOutputStream with the given Deflater and default buffer size.
DeflaterOutputStream ( Stream baseOutputStream, Deflater deflater, int bufferSize ) : System	Creates a new DeflaterOutputStream with the given Deflater and buffer size.
Finish ( ) : void	Finishes the stream by calling finish() on the deflater.
Flush ( ) : void	Flushes the stream by calling Flush on the deflater and then on the underlying stream. This ensures that all bytes are flushed.
Read ( byte buffer, int offset, int count ) : int	Read a block of bytes from stream
ReadByte ( ) : int	Read a byte from stream advancing position by one
Seek ( long offset, SeekOrigin origin ) : long	Sets the current position of this stream to the given value. Not supported by this class!
SetLength ( long value ) : void	Sets the length of this stream to the given value. Not supported by this class!
Write ( byte buffer, int offset, int count ) : void	Writes bytes from an array to the compressed stream.
WriteByte ( byte value ) : void	Writes a single byte to the compressed output stream.

Защищенные методы

Метод	Описание
Deflate ( ) : void	Deflates everything in the input buffers. This will call `def.deflate()` until all bytes from the input buffers are processed.
Dispose ( bool disposing ) : void	Calls Finish and closes the underlying stream when is true.
EncryptBlock ( byte buffer, int offset, int length ) : void	Encrypt a block of data
InitializeAESPassword ( ZipEntry entry, string rawPassword, byte &salt, byte &pwdVerifier ) : void	Initializes encryption keys based on given password.
InitializePassword ( string password ) : void	Initializes encryption keys based on given password.

Описание методов

Deflate() защищенный Метод

Deflates everything in the input buffers. This will call def.deflate() until all bytes from the input buffers are processed.

protected Deflate ( ) : void
Результат	void

DeflaterOutputStream() публичный Метод

Creates a new DeflaterOutputStream with a default Deflater and default buffer size.

public DeflaterOutputStream ( Stream baseOutputStream ) : System
baseOutputStream	Stream	/// the output stream where deflated output should be written. ///
Результат	System

DeflaterOutputStream() публичный Метод

Creates a new DeflaterOutputStream with the given Deflater and default buffer size.

public DeflaterOutputStream ( Stream baseOutputStream, Deflater deflater ) : System
baseOutputStream	Stream	/// the output stream where deflated output should be written. ///
deflater	ICSharpCode.SharpZipLib.Zip.Compression.Deflater	/// the underlying deflater. ///
Результат	System

DeflaterOutputStream() публичный Метод

Creates a new DeflaterOutputStream with the given Deflater and buffer size.

/// bufsize is less than or equal to zero. /// /// baseOutputStream does not support writing /// /// deflater instance is null ///

public DeflaterOutputStream ( Stream baseOutputStream, Deflater deflater, int bufferSize ) : System

bufferSize	int	/// The buffer size in bytes to use when deflating (minimum value 512) ///
Результат	System

Dispose() защищенный Метод

Calls Finish and closes the underlying stream when is true.

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

EncryptBlock() защищенный Метод

Encrypt a block of data

protected EncryptBlock ( byte buffer, int offset, int length ) : void
