Closes the current StringWriter and the underlying stream.

This code example is part of a larger example provided for the StringWriter(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() );
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());
strWriter.Close()
' Since the StringWriter is closed, an exception will

strBuilder.Insert(0, "Invalid ")
Console.WriteLine(strWriter.ToString())

This method overrides Stream.Close.
This implementation of Close calls the Dispose method passing a true value.
Flushing the stream will not flush its underlying encoder unless you explicitly call 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.
