Xml Serializer in memory.

My object name is request.
and I send TextReader parameter to ChargeRequestFactory Object
This explain simple 2 way to do about this.
But because StringWriter has alway create xml with utf 16 encoding
and I need UTF 8 instead so my choice is choose to use in second solution

Yes we can use StringWriter to create XML with UTF 8 but it must create new
Class and override Encoding so Second task look enough for me.

(1)
StringWriter stringWriter = new StringWriter();

xmlSerializer.Serialize( stringWriter, request );

StringReader stringReader = new StringReader( stringWriter.ToString() );

ChargeRequestFactory factory = new ChargeRequestFactory( stringReader );

(2)
Stream s = new MemoryStream();

XmlWriter xw = new XmlTextWriter( s, Encoding.UTF8 );

xmlSerializer.Serialize( xw, request );

TextReader tr = new StreamReader( s );

s.Seek( 0, SeekOrigin.Begin );

ChargeRequestFactory factory = new ChargeRequestFactory( tr );

In ChargeRequest function I have Deserialize to get XML Back to Object.
