Contains types that facilitate reading from and writing to data streams.
Classes
Class | Description | |
---|---|---|
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. | |
File | Provides static methods for the creation, copying, deletion, moving, and opening of files, and aids in the creation of FileStream objects. | |
FileEnum | Contains members for working with files. | |
FileEnumerator | Exposes the file enumerator, which supports a simple iteration over a collection. | |
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 | Exposes a Stream around 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 | Performs operations on String instances that contain file or directory path information. These operations are performed in a cross-platform manner. | |
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. | |
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. |
Enumerations
Enumeration | Description | |
---|---|---|
FileAccess | Defines constants for read, write, or read/write access to a file. | |
FileAttributes | Provides attributes for files and directories. | |
FileEnumFlags | Contains values to represent files and directories. | |
FileMode | Specifies how the operating system should open a file. | |
FileShare | Contains constants for controlling the kind of access other FileStream objects can have to the same file. | |
IOException. . :: . .IOExceptionErrorCode | Provides values for error codes. | |
SeekOrigin | Specifies the position in a stream to use for seeking. |
