Writer. Close Method
Closes the current
StreamWriter object and the underlying stream.
public: override void Close();
public override void Close ();
override this.Close : unit -> unit
Public Overrides Sub Close ()
The current encoding does not support displaying half of a Unicode surrogate pair.
The following code example demonstrates the
// close the file by closing the writer sw->Close();
// close the file by closing the writer sw.Close();
' Close the file by closing the writer. Sw.Close()
This method overrides Stream.Close.
You must call Close to ensure that all data is correctly written out to the underlying stream. Following a call to Close, any operations on the StreamWriter might raise exceptions. If there is insufficient space on the disk, calling Close will raise an exception.
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.
