| Description | |
|
The BufferedStream class provides direct read and write access to a stream. This access is buffered to improve performance.
The buffer size is 4,096 bytes by default, but may be overriden.
BufferedStream can be used with BinaryReader and BinaryWriter for handling low level data, but you are restricted to read or write operations appropriately.
Some streams, support direct read and write access. You can use a buffered stream to access these - see the Seek mtheod example code. |
