System.IO.Compression Namespace

Contains classes that provide basic compression and decompression services for streams.

Classes

BrotliCompressionOptions

Provides compression options to be used with BrotliStream.
BrotliStream

Provides methods and properties used to compress and decompress streams by using the Brotli data format specification.
DeflateStream

Provides methods and properties for compressing and decompressing streams by using the Deflate algorithm.
GZipStream

Provides methods and properties used to compress and decompress streams by using the GZip data format specification.
ZipArchive

Represents a package of compressed files in the zip archive format.
ZipArchiveEntry

Represents a compressed file within a zip archive.
ZipFile

Provides static methods for creating, extracting, and opening zip archives.
ZipFileExtensions

Provides extension methods for the ZipArchive and ZipArchiveEntry classes.
ZLibCompressionOptions

Provides compression options to be used with ZLibStream, DeflateStream, and GZipStream.
ZLibStream

Provides methods and properties used to compress and decompress streams by using the zlib data format specification.

Structs

BrotliDecoder

Provides non-allocating, performant Brotli decompression methods. The methods decompress in a single pass without using a BrotliStream instance.
BrotliEncoder

Provides methods and static methods to encode and decode data in a streamless, non-allocating, and performant manner using the Brotli data format specification.

Enums

CompressionLevel

Specifies values that indicate whether a compression operation emphasizes speed or compression size.
CompressionMode

Specifies whether to compress data to or decompress data from the underlying stream.
ZipArchiveMode

Specifies values for interacting with zip archive entries.
ZLibCompressionStrategy

Defines the compression algorithms that can be used for DeflateStream, GZipStream, and ZLibStream.
