Valor de propiedad

XmlAttributes que representa la colección de atributos de reemplazo.

Ejemplos

En el ejemplo siguiente se crea un XmlAttributeOverrides objeto, un XmlAttributes objeto y un XmlRootAttribute objeto . En el ejemplo se asigna a XmlRootAttribute la XmlRoot propiedad del XmlAttributes objeto y se agrega el XmlAttributes objeto al XmlAttributeOverrides objeto . Por último, el ejemplo obtiene el XmlAttributes objeto pasando la Type clase serializada al XmlAttributeOverrides objeto . En este ejemplo, Type es Group.

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

   [XmlAttributeAttribute]
   int GroupCode;
};

public ref class Sample

      XmlAttributes^ attrs = gcnew XmlAttributes;
      XmlAttributeOverrides^ xOver = gcnew XmlAttributeOverrides;
      XmlRootAttribute^ xRoot = gcnew XmlRootAttribute;

      // Set a new Namespace and ElementName for the root element.
      xRoot->Namespace = "http://www.cpandl.com";
      xRoot->ElementName = "NewGroup";
      attrs->XmlRoot = xRoot;
      xOver->Add( Group::typeid, attrs );

      // Get the XmlAttributes object, based on the type.
      XmlAttributes^ tempAttrs;
      tempAttrs = xOver[ Group::typeid ];

      // Print the Namespace and ElementName of the root.
      Console::WriteLine( tempAttrs->XmlRoot->Namespace );

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

Comentarios

Utilice esta sobrecarga para devolver un XmlAttributes objeto que contiene atributos para un XmlRootAttribute objeto o XmlTypeAttribute .

Si el XmlAttributes objeto contiene objetos que reemplazan a , XmlArrayAttributeXmlArrayItemAttribute, XmlEnumAttributeXmlElementAttribute, o XmlAttributeAttribute, debe usar la sobrecarga que especifica el miembro invalidado, así como el tipo .

Utilice esta sobrecarga para devolver un XmlAttributes objeto que contiene objetos que reemplazan a XmlArrayAttribute, XmlArrayItemAttribute, XmlElementAttributeXmlAttributeAttribute, o XmlEnumAttribute. Si el XmlAttributes objeto contiene o XmlRootAttributeXmlTypeAttribute, debe usar la sobrecarga que especifica solo el tipo invalidado.
