XmlElementAttributes.Add Method

Adds an XmlElementAttribute to the collection.

Namespace:  System.Xml.Serialization
Assemblies:   System.Xml (in System.Xml.dll)
  System.Xml.XmlSerializer (in System.Xml.XmlSerializer.dll)

Public Function Add ( _
	attribute As XmlElementAttribute _
) As Integer

Return Value

The zero-based index of the newly added item.

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 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.

        ' Create a second XmlElementAttribute, and 
        ' add to the collection.  
        Dim xElement2 As New XmlElementAttribute(GetType(Train))

        ' 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
    End Function 
End Class
