System.IO namespaces

The System.IO and System.IO.Compression namespaces contain types that support reading and writing data to streams, and basic compression and decompression services for streams.

This topic displays the types in the System.IO and System.IO.Compression namespaces that are included in the .NET for Windows Store apps. Note that the .NET for Windows Store apps does not include all the members of each type. For information about individual types, see the linked topics. The documentation for a type indicates which members are included in the .NET for Windows Store apps.

System.IO namespace

Types supported in the .NET for Windows Store apps	Description
BinaryReader	Reads primitive data types as binary values in a specific encoding.
BinaryWriter	Writes primitive types in binary to a stream and supports writing strings in a specific encoding.
EndOfStreamException	The exception that is thrown when reading is attempted past the end of a stream.
FileNotFoundException	The exception that is thrown when an attempt to access a file that does not exist on disk fails.
InvalidDataException	The exception that is thrown when a data stream is in an invalid format.
IOException	The exception that is thrown when an I/O error occurs.
MemoryStream	Creates a stream whose backing store is memory.
Path	Performs operations on String instances that contain file or directory path information. These operations are performed in a cross-platform manner.
SeekOrigin	Provides the fields that represent reference points in streams for seeking.
Stream	Provides a generic view of a sequence of bytes.
StreamReader	Implements a TextReader that reads characters from a byte stream in a particular encoding.
StreamWriter	Implements a TextWriter for writing characters to a stream in a particular encoding.
StringReader	Implements a TextReader that reads from a string.
StringWriter	Implements a TextWriter for writing information to a string. The information is stored in an underlying StringBuilder.
TextReader	Represents a reader that can read a sequential series of characters.
TextWriter	Represents a writer that can write a sequential series of characters. This class is abstract.
WindowsRuntimeStorageExtensions	Contains extension methods for the IStorageFile and IStorageFolder interfaces in the Windows Runtime when developing Windows Store apps.
WindowsRuntimeStreamExtensions	Contains extension methods for converting between streams in the Windows Runtime and managed streams in the .NET for Windows Store apps.

System.IO.Compression namespace

Types supported in the .NET for Windows Store apps	Description
CompressionLevel	Specifies values that indicate whether a compression operation emphasizes speed or compression size.
CompressionMode	Specifies whether to compress or decompress the underlying stream.
DeflateStream	Provides methods and properties for compressing and decompressing streams using the Deflate algorithm.
GZipStream	Provides methods and properties used to compress and decompress streams.
ZipArchive	Represents a zip archive.
ZipArchiveEntry	Represents an entry in the zip archive.
ZipArchiveMode	Specifies values for interacting with zip archive entries.
