A Stream class forms the abstract class of all other streams. That is, you cannot directly create an instance of the Stream class. Instead, the Stream class is implemented by the following classes: --> BufferedStream : provides a buffering layer on another stream to improve performance. FileStream : provides a way to read and write files. MemoryStream : provides a stream using memory as the backing store. NetworkStream : provides a way to access data on the network. CryptoStream : provides a way to supply data for cryptographic transformation. Streams fundamentally involve the following operations: Reading Writing Seeking You can read from streams. Reading is the transfer of data from a stream into a data structure, such as an array of bytes. You can write to streams. Writing is the transfer of data from a data structure into a stream. Streams can support seeking. Seeking is the querying and modifying of the current position within a stream. Seek capability depends on the kind of backing store a stream has. For example, network streams have no unified concept of a current position, and therefore typically do not support seeking. Namespace: System.IO Example: for creating a file FileStream file = new FileStream("path.txt", FileMode, FileAccess); write in the file FileStream file = new FileStream ( "c://test.txt" , FileMode .Open, FileAccess .Write); StreamWriter sw = new StreamWriter (file); sw.Write( "Hello file system world!" ); sw.Close(); Reading from a file FileStream file = new FileStream ( "c://test.txt" , FileMode .Open, FileAccess .Read); StreamReader sr = new StreamReader (file); string s = sr.ReadToEnd(); sr.Close(); file.Close(); ******************************* pls mark it Accepted if u find it helpful

A stream is an important concept in modern programming. Earlier programming languages such as Fortran, Cobol and Basic had input and output built in to those languages. Modern languages like C , C++ and C# tend to avoid having this and instead implement input and output via library functions . Output involves sending a stream of byte to a device and whether that device is the screen, an object in memory, a file on disk, another computer on a network or a printer is unimportant. The same routines can be used with different destinations. In earlier languages you needed separate routines to handle each device. Streams make this flexibility possible. show also this articles http://www.aspfree.com/c/a/C-Sharp/C-Sharp-FileStream-Explained/ http://www.c-sharpcorner.com/UploadFile/Ashish1/memorystream10272005214644PM/memorystream.aspx http://www.c-sharpcorner.com/UploadFile/mahesh/FileStreamReadorWriteDataStreams12022005072329AM/FileStreamReadorWriteDataStreams.aspx
