StreamWriter.Flush Method

Namespace: System.IO
Assembly: mscorlib (in mscorlib.dll)

public override void Flush ()
public void Flush ()
public override function Flush ()
Not applicable.

Exception typeCondition

ObjectDisposedException

The current writer is closed.

IOException

An I/O error has occurred.

EncoderFallbackException

The current encoding does not support displaying half of a Unicode surrogate pair.

This method overrides 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.
