String

Nombre del elemento XML de la matriz serializada. El valor predeterminado es el nombre del miembro al que se ha asignado XmlArrayAttribute.

Ejemplos

En el ejemplo siguiente se serializa una instancia de la Library clase que contiene una propiedad denominada Books que devuelve una matriz de Book elementos. En el ejemplo se usa la ElementName propiedad para especificar que la matriz de elementos XML debe tener un nombre My_Books en lugar de Books.

Comentarios

Especifique un ElementName valor cuando desee que el nombre del elemento XML generado sea diferente del identificador del miembro.

Puede establecer el mismo ElementName valor en más de un miembro siempre que el documento XML generado use espacios de nombres XML para distinguir entre los miembros con nombre idéntico. Para obtener más información sobre el uso de espacios de nombres y la creación de nombres con prefijos en el documento XML, vea XmlSerializerNamespaces.
