XmlNodeReader.Name Propriedade

Definição

Obtém o nome qualificado do nó atual.

public:
 virtual property System::String ^ Name { System::String ^ get(); };
public override string Name { get; }
member this.Name : string
Public Overrides ReadOnly Property Name As String

Valor da propriedade

String

O nome qualificado do nó atual. Por exemplo, Name é bk:book para o elemento <bk:book>.

O nome retornado depende do NodeType do nó. Os seguintes tipos de nó retornam os valores listados. Todos os outros tipos de nó retornam uma cadeia de caracteres vazia.

Tipo de nó Nome
Attribute O nome do atributo.
DocumentType O nome do tipo de documento.
Element O nome da marcação.
EntityReference O nome da entidade referenciada.
ProcessingInstruction O destino da instrução de processamento.
XmlDeclaration A cadeia de caracteres literal xml.

Exemplos

O exemplo a seguir lê um XML e exibe cada um dos nós.

  <Item>Test with a char entity: A</Item>
  <!-- Fourteen chars in this element.-->
  <Item>1234567890ABCD</Item>

Observação

No .NET Framework 2.0, a prática recomendada é criar XmlReader instâncias usando a XmlReaderSettings classe e o Create método. Isso permite que você aproveite ao máximo todos os novos recursos introduzidos no .NET Framework. Para obter mais informações, consulte a seção Comentários na XmlReader página de referência.
