Exemples

L’exemple suivant crée deux XmlElementAttribute objets et appelle la Add méthode pour les ajouter à un XmlElementAttributes. L’exemple ajoute ensuite à XmlElementAttributes un XmlAttributeOverrides, qui est utilisé pour créer un XmlSerializer qui peut sérialiser une instance de la Transportation classe .

public:
   XmlSerializer^ CreateOverrider()
   {
      // Create XmlAttributes and XmlAttributeOverrides instances.

      XmlAttributes^ attrs = gcnew XmlAttributes;
      XmlAttributeOverrides^ xOver =
         gcnew XmlAttributeOverrides;

      /* Create an XmlElementAttributes to override 
            the Vehicles property. */
      XmlElementAttribute^ xElement1 =
         gcnew XmlElementAttribute( Truck::typeid );
      // Add the XmlElementAttribute to the collection.
      attrs->XmlElements->Add( xElement1 );

      /* Create a second XmlElementAttribute, and 
            add to the collection. */
      XmlElementAttribute^ xElement2 =
         gcnew XmlElementAttribute( Train::typeid );
      attrs->XmlElements->Add( xElement2 );

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

      // Create the XmlSerializer, and return it.
      XmlSerializer^ xSer = gcnew XmlSerializer(
         Transportation::typeid,xOver );
      return xSer;
   }

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;
}

    Public Function CreateOverrider() As XmlSerializer
        ' Create XmlAttributes and XmlAttributeOverrides instances.
        Dim attrs As New XmlAttributes()
        Dim xOver As New XmlAttributeOverrides()
        
        ' Create an XmlElementAttributes to override
        ' the Vehicles property. 
        Dim xElement1 As New XmlElementAttribute(GetType(Truck))
        ' Add the XmlElementAttribute to the collection.
        attrs.XmlElements.Add(xElement1)
        
        ' Create a second XmlElementAttribute, and
        ' add to the collection. 
        Dim xElement2 As New XmlElementAttribute(GetType(Train))
        attrs.XmlElements.Add(xElement2)
        
        ' Add the XmlAttributes to the XmlAttributeOverrides,
        ' specifying the member to override. 
        xOver.Add(GetType(Transportation), "Vehicles", attrs)
        
        ' Create the XmlSerializer, and return it.
        Dim xSer As New XmlSerializer(GetType(Transportation), xOver)
        Return xSer
