System.IO.Compression Namespace

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

Classes

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.
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.
