Comentários
A tabela a seguir mostra os valores de propriedade inicial de uma instância de SoapFormatter.
Propriedade | Valor |
---|---|
SurrogateSelector | null |
Context | Um novo StreamingContext inicializado para especificar que os dados serializados podem ser transmitidos ou recebidos de qualquer um dos outros contextos |
Aplica-se a
SoapFormatter(ISurrogateSelector, StreamingContext)
Inicializa uma nova instância da classe SoapFormatter com o ISurrogateSelector e StreamingContext especificados.
public:
SoapFormatter(System::Runtime::Serialization::ISurrogateSelector ^ selector, System::Runtime::Serialization::StreamingContext context);
public SoapFormatter (System.Runtime.Serialization.ISurrogateSelector selector, System.Runtime.Serialization.StreamingContext context);
new System.Runtime.Serialization.Formatters.Soap.SoapFormatter : System.Runtime.Serialization.ISurrogateSelector * System.Runtime.Serialization.StreamingContext -> System.Runtime.Serialization.Formatters.Soap.SoapFormatter
Public Sub New (selector As ISurrogateSelector, context As StreamingContext)
Parâmetros
- selector
- ISurrogateSelector
O ISurrogateSelector a ser usado com a nova instância de SoapFormatter. Pode ser null
.
- context
- StreamingContext
O StreamingContext que contém a origem e o destino da serialização. Se o parâmetro context
for null
, o Context usará CrossMachine como padrão.
Comentários
Os objetos são serializados ou desserializados do especificado Stream.
O processo de serialização ou desserialização usa o especificado ISurrogateSelector para pesquisar substitutos registrados para os tipos de objeto que você deseja desserializar. Substitutos são auxiliares que serializam e desserializam objetos de classes específicas. O padrão ISurrogateSelector não pode lidar com a serialização de objetos que derivam do MarshalByRefObject para fins de comunicação remota. Em uma situação de comunicação remota, o especificado ISurrogateSelector substitui o objeto derivado de MarshalByRefObject por um ObjRef objeto serializado pelo seletor substituto especificado. Portanto, se você quiser usar objetos remotos, defina o selector
parâmetro como uma instância do RemotingSurrogateSelector. Se você não precisar de substitutos, defina o selector
parâmetro como null
.
