public override void Close()

For an example of creating a file and writing text to a file, see [<topic://cpconwritingtexttofile>]. For an example of reading text from a file, see [<topic://cpconreadingtextfromfile>]. For an example of reading from and writing to a binary file, see [<topic://cpconReadingWritingToNewlyCreatedDataFile>].

This method overrides M:System.IO.Stream.Close.

This implementation of Close calls the M:System.IO.StringWriter.Dispose(System.Boolean) method passing a true value.

Flushing the stream will not flush its underlying encoder unless you explicitly call Close. Setting P:System.IO.StreamWriter.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.

This code example is part of a larger example provided for the M:System.IO.StringWriter.#ctor(System.Text.StringBuilder) constructor.

strWriter.Close();

// Since the StringWriter is closed, an exception will 
// be thrown if the Write method is called. However, 
// the StringBuilder can still manipulate the string.
strBuilder.Insert(0, "Invalid ");
Console.WriteLine(strWriter.ToString());
