CryptoStream.Flush Method


Clears all buffers for the current stream and causes any buffered data to be written to the underlying device.

 override void Flush();
public override void Flush ();
override this.Flush : unit -> unit
Public Overrides Sub Flush ()


Flushing the stream will not flush its underlying encoder unless you explicitly call Flush or Close. Setting AutoFlush to true means that data will be flushed from the buffer to the stream, but the encoder state will not be flushed. This allows the encoder to keep its state (partial characters) so that it can encode the next block of characters correctly. This scenario affects UTF8 and UTF7 where certain characters can only be encoded after the encoder receives the adjacent character or characters.


You should call either the Close method or the FlushFinalBlock method to complete flushing the buffer.
