The IXmlSerializable.WriteXml(System.Xml.XmlWriter) implementation you provide should write out the XML representation of the object. The framework writes a wrapper element and positions the XML writer after its start. Your implementation may write its contents, including child elements. The framework then closes the wrapper element.

Write sufficient information to the System.Xml.XmlWriter stream to allow the IXmlSerializable.ReadXml(System.Xml.XmlReader) method to reconstitute your object.

For example, if your object state includes an array variable, be sure to write the length of the array, or use a parent element to contain the elements that describe the array values, so that you know how many values to read when the object is reconstituted.
