public int Add (System.Xml.Serialization.XmlElementAttribute? attribute);
member this.Add : System.Xml.Serialization.XmlElementAttribute -> int
Public Function Add (attribute As XmlElementAttribute) As Integer

Parameters

Returns

The zero-based index of the newly added item.

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.

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
