I want to clear all of content in XmlTextWriter and StringWriter. Flush() didn't work out.

XmlDocument doc = new XmlDocument(); StringWriter sw = new StringWriter(); XmlTextWriter xw = new XmlTextWriter(sw);

xw.WriteStartElement("AddPhoneQual"); xw.WriteElementString("Type", "B"); xw.WriteElementString("PhoneNumber", bookingDetails.PassengerList[0].PhoneNumber); xw.WriteEndElement(); // End AddPhoneQual

doc.LoadXml(sw.ToString());

Now, i need to clear all of content and start to write in clear xw.

xw.Flush(); sw.Flush();

They didn't work.

c# xmltextwriter stringwriter
