Public Methods

Method	Description
CloseEntry ( ) : void	Closes the current entry, updating header and footer information as required
Finish ( ) : void	Finishes the stream. This will write the central directory at the end of the zip file and flush the stream. This is automatically called when the stream is closed.
GetLevel ( ) : int	Get the current deflater compression level
PutNextEntry ( ZipEntry entry ) : void	Starts a new Zip entry. It automatically closes the previous entry if present. All entry elements bar name are optional, but must be correct if present. If the compression method is stored and the output is not patchable the compression for that entry is automatically changed to deflate level 0
SetComment ( string comment ) : void	Set the zip file comment.
SetLevel ( int level ) : void	Sets the compression level. The new level will be activated immediately.
Write ( byte buffer, int offset, int count ) : void	Writes the given buffer to the current entry.
ZipOutputStream ( Stream baseOutputStream ) : System	Creates a new Zip output stream, writing a zip archive.
ZipOutputStream ( Stream baseOutputStream, int bufferSize ) : System	Creates a new Zip output stream, writing a zip archive.

Method Details

CloseEntry() public method

Closes the current entry, updating header and footer information as required

/// An I/O error occurs. /// /// No entry is active. ///

public CloseEntry ( ) : void
return	void

Finish() public method

Finishes the stream. This will write the central directory at the end of the zip file and flush the stream.

This is automatically called when the stream is closed.

/// An I/O error occurs. /// /// Comment exceeds the maximum length
/// Entry name exceeds the maximum length ///

public Finish ( ) : void
return	void

GetLevel() public method

Get the current deflater compression level

public GetLevel ( ) : int
return	int

PutNextEntry() public method

Starts a new Zip entry. It automatically closes the previous entry if present. All entry elements bar name are optional, but must be correct if present. If the compression method is stored and the output is not patchable the compression for that entry is automatically changed to deflate level 0

/// if entry passed is null. /// /// if an I/O error occured. /// /// if stream was finished /// /// Too many entries in the Zip file
/// Entry name is too long
/// Finish has already been called
///

public PutNextEntry ( ZipEntry entry ) : void
entry	ZipEntry	/// the entry. ///
return	void

SetComment() public method

Set the zip file comment.

/// The converted comment is longer than 0xffff bytes. ///

public SetComment ( string comment ) : void
comment	string	/// The comment text for the entire archive. ///
return	void

SetLevel() public method

Sets the compression level. The new level will be activated immediately.

/// Level specified is not supported. ///

public SetLevel ( int level ) : void
level	int	The new compression level (1 to 9).
return	void

Write() public method

Writes the given buffer to the current entry.

Archive size is invalid No entry is active.

public Write ( byte buffer, int offset, int count ) : void
buffer	byte	The buffer containing data to write.
offset	int	The offset of the first byte to write.
count	int	The number of bytes to write.
return	void

ZipOutputStream() public method

Creates a new Zip output stream, writing a zip archive.

public ZipOutputStream ( Stream baseOutputStream ) : System
baseOutputStream	Stream	/// The output stream to which the archive contents are written. ///
return	System

ZipOutputStream() public method

Creates a new Zip output stream, writing a zip archive.

public ZipOutputStream ( Stream baseOutputStream, int bufferSize ) : System
baseOutputStream	Stream	The output stream to which the archive contents are written.
bufferSize	int	Size of the buffer to use.
return	System
