XmlArrayAttribute.ElementName XmlArrayAttribute.ElementName XmlArrayAttribute.ElementName XmlArrayAttribute.ElementName Property


Gets or sets the XML element name given to the serialized array.

 property System::String ^ ElementName { System::String ^ get(); void set(System::String ^ value); };
public string ElementName { get; set; }
member this.ElementName : string with get, set
Public Property ElementName As String

Property Value

The XML element name of the serialized array. The default is the name of the member to which the XmlArrayAttribute is assigned.


The following example serializes an instance of the Library class that contains a property named Books that returns an array of Book items. The example uses the ElementName property to specify that the array of XML elements should be named My_Books rather than Books.

Specify an ElementName when you want the generated XML element name to differ from the member's identifier.

You can set the same ElementName value to more than one member as long as the generated XML document uses XML namespaces to distinguish between the identically named members. For more details about using namespaces and creating prefixed names in the XML document, see XmlSerializerNamespaces.
