By default, all public fields and public read/write properties are serialized by the XmlSerializer. That is, the value of each public field or property is persisted as an XML element or XML attribute in an XML-document instance.
To override the default serialization of a field or property, create an XmlAttributes object, and set its XmlIgnore property to true. Add the object to an XmlAttributeOverrides object and specify the type of the object that contains the field or property to ignore, and the name of the field or property to ignore.
If an XmlIgnoreAttribute is applied to a field or property, the field or property is ignored. However you can override that behavior by creating an XmlAttributes object, setting its XmlIgnore property to false, adding it to an XmlAttributeOverrides object specifying the type of the object that contains the field or property, and the name of the field or property.
