Namespace System.IO
Classes
- Directory
Exposes static methods for creating, moving, and enumerating through directories and subdirectories. This class cannot be inherited.
- DirectoryInfo
Exposes instance methods for creating, moving, and enumerating through directories and subdirectories. This class cannot be inherited.
- DriveInfo
Provides access to information on a drive.
- File
Provides static methods for the creation, copying, deletion, moving, and opening of a single file, and aids in the creation of FileStream objects.
- FileInfo
Provides properties and instance methods for the creation, copying, deletion, moving, and opening of files, and aids in the creation of FileStream objects. This class cannot be inherited.
- FileStream
Provides a Stream for a file, supporting both synchronous and asynchronous read and write operations.
- FileSystemInfo
Provides the base class for both FileInfo and DirectoryInfo objects.
- IOException
The exception that is thrown when an I/O error occurs.
- MemoryStream
Creates a stream whose backing store is memory.
- Path
Provides methods for processing file system strings in a cross-platform manner. Most of the methods don't do a complete parsing (such as examining a UNC hostname), but they will handle most string operations.
- Stream
Provides a generic view of a sequence of bytes. This is an abstract class.
- 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.
- 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.
Enums
- DriveType
Defines constants for drive types, including CDRom, Fixed, Network, NoRootDirectory, Ram, Removable, and Unknown.
- FileAccess
Contains constants for specifying the access you want for a file. You can have Read, Write or ReadWrite access.
- FileAttributes
Provides attributes for files and directories.
- FileMode
Contains constants for specifying how the OS should open a file. These will control whether you overwrite a file, open an existing file, or some combination thereof.
To append to a file, use Append (which maps to OpenOrCreate then we seek to the end of the file). To truncate a file or create it if it doesn't exist, use Create.
- FileShare
Contains constants for controlling file sharing options while opening files. You can specify what access other processes trying to open the same file concurrently can have.
- IOException.IOExceptionErrorCode
Provides values for error codes.
- SeekOrigin
Specifies the position in a stream to use for seeking.
