Use the XmlAnyElementAttributes to override the behavior of a set of XmlAnyElementAttribute objects. Multiple instances of the XmlAnyElementAttribute class can be applied to a class member, as long as each instance has a distinct Name property value; this instructs the XmlSerializer to collect unknown elements under the named element into the appropriate array. It is for this reason that multiple instances of the XmlAnyElementAttribute class can be added to the XmlAnyElementAttributes.

To override a set of XmlAnyElementAttribute objects:

  1. Create an XmlAnyElementAttributes.

  2. Create the set of XmlAnyElementAttribute objects, and add each object to the collection using the Add method.

  3. Create an XmlAttributes.

  4. Set the XmlAnyElements property to the XmlAnyElementAttributes.

  5. Create an XmlAttributeOverrides.

  6. Add the XmlAttributes to the XmlAttributeOverrides using the Add method.

  7. Create an instance of the XmlSerializer using the XmlAttributeOverrides.

  8. Serialize or deserialize an object that contains the set of XmlAnyElementAttribute objects.

The following example creates a new XmlAnyElementAttribute and adds it to the collection of objects accessed through the XmlAnyElements property. The XmlAttributes is then added to a XmlAttributeOverrides which is used to create an XmlSerializer. The XmlSerializer is used to serialize or deserialize an object. To see the effect of using the XmlAnyElementAttributes property, create an XML document named UnknownElements.xml by running the SerializeObject method in the Main method. Edit the resulting document to include other (unknown) elements. Comment out the SerializeObject call in the Main method, and uncomment the call to the DeserializeObject method, which prints out the name and value of any unknown XML element.
