public System.Xml.Serialization.XmlAttributes? this[Type type] { get; }

member this.Item(Type) : System.Xml.Serialization.XmlAttributes

Default Public ReadOnly Property Item(type As Type) As XmlAttributes

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
{
public:
   XmlSerializer^ CreateOverrider()

      // Create an XmlSerializer with overriding attributes.
      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 );
      Console::WriteLine( tempAttrs->XmlRoot->ElementName );
      XmlSerializer^ xSer = gcnew XmlSerializer( Group::typeid,xOver );
      return xSer;
   }
};

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

   xOver.Add(typeof(Group), attrs);

   // Get the XmlAttributes object, based on the type.
   XmlAttributes tempAttrs;
   tempAttrs = xOver[typeof(Group)];

   // Print the Namespace and ElementName of the root.

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.
