Parâmetros

Valor da propriedade

XmlAttributes

Um XmlAttributes que representa a coleção de atributos de substituição.

Exemplos

O exemplo a seguir cria um XmlAttributeOverrides objeto, um XmlAttributes objeto e um XmlRootAttribute objeto. O exemplo atribui a XmlRootAttribute XmlRoot propriedade do XmlAttributes objeto e adiciona o XmlAttributes objeto ao XmlAttributeOverrides objeto. Por fim, o exemplo obtém o XmlAttributes objeto passando a Type classe serializada para o XmlAttributeOverrides objeto. Neste exemplo, o Type valor é Group.

// This is the class that will be serialized.
public ref class Group
{
public:
   String^ GroupName;

   [XmlAttributeAttribute]
   int GroupCode;
};

public ref class Sample

      // Set a new Namespace and ElementName for the root element.
      xRoot->Namespace = "http://www.cpandl.com";
      xRoot->ElementName = "NewGroup";

      xOver->Add( Group::typeid, attrs );

      // Get the XmlAttributes object, based on the type.

Comentários

Use essa sobrecarga para retornar um XmlAttributes objeto que contém atributos para um XmlRootAttribute ou XmlTypeAttribute objeto.

Se o XmlAttributes objeto contiver objetos que substituem um XmlArrayAttribute, XmlArrayItemAttribute, XmlElementAttribute, XmlEnumAttributeou XmlAttributeAttribute, você deve usar a sobrecarga que especifica o membro substituído, bem como o tipo.

Comentários

Use essa sobrecarga para retornar um XmlAttributes objeto que contém objetos que substituem um XmlArrayAttribute, XmlArrayItemAttribute, , XmlAttributeAttributeou XmlElementAttributeXmlEnumAttribute. Se o XmlAttributes objeto contiver um XmlRootAttribute ou XmlTypeAttribute, você deverá usar a sobrecarga que especifica apenas o tipo substituído.
