Examples

The following example creates two XmlElementAttribute objects and calls the Add method to add them to an XmlElementAttributes. The example then adds the XmlElementAttributes to an XmlAttributeOverrides, which is used to create an XmlSerializer that can serialize an instance of the Transportation class.

C#
public XmlSerializer CreateOverrider()
{
   // Create XmlAttributes and XmlAttributeOverrides instances.

   XmlAttributes attrs = new XmlAttributes();
   XmlAttributeOverrides xOver =
   new XmlAttributeOverrides();

   /* Create an XmlElementAttributes to override
      the Vehicles property. */
   XmlElementAttribute xElement1 =
   new XmlElementAttribute(typeof(Truck));
   // Add the XmlElementAttribute to the collection.
   attrs.XmlElements.Add(xElement1);

   /* Create a second XmlElementAttribute, and
      add to the collection. */
   XmlElementAttribute xElement2 =
   new XmlElementAttribute(typeof(Train));
   attrs.XmlElements.Add(xElement2);

   /* Add the XmlAttributes to the XmlAttributeOverrides,
      specifying the member to override. */
   xOver.Add(typeof(Transportation), "Vehicles", attrs);

   // Create the XmlSerializer, and return it.
   XmlSerializer xSer = new XmlSerializer
   (typeof(Transportation), xOver);
   return xSer;
}
