Ejemplos
En el ejemplo siguiente se crea un XmlTypeAttribute objeto y se asigna a la XmlType propiedad de un XmlAttributes objeto .
#using <System.Xml.dll>
#using <System.dll>
using namespace System;
using namespace System::IO;
using namespace System::Xml::Serialization;
public ref class Car
{
public:
int ID;
};
public ref class Transportation
{
public:
array<Car^>^Cars;
};
// Return an XmlSerializer used for overriding.

{
// Create the XmlAttributes and XmlAttributeOverrides objects.

XML type. */

Comentarios
XmlTypeAttribute se puede usar para controlar cómo serializa un tipo .XmlSerializer Por ejemplo, de forma predeterminada, cuando se serializa un tipo, usa XmlSerializer el nombre de clase como nombre del elemento XML. Al crear un XmlTypeAttributeobjeto , establecer la XmlType propiedad en él y crear un XmlAttributeOverrides objeto , puede cambiar el nombre del elemento XML.
