NetworkInterface.IsReceiveOnly Propiedad
Definición
Importante
Parte de la información hace referencia a la versión preliminar del producto, que puede haberse modificado sustancialmente antes de lanzar la versión definitiva. Microsoft no otorga ninguna garantía, explícita o implícita, con respecto a la información proporcionada aquí.
Obtiene un valor Boolean que indica si la interfaz de red está establecida para recibir paquetes de datos únicamente.
public:
virtual property bool IsReceiveOnly { bool get(); };
public:
abstract property bool IsReceiveOnly { bool get(); };
public virtual bool IsReceiveOnly { get; }
public abstract bool IsReceiveOnly { get; }
member this.IsReceiveOnly : bool
Public Overridable ReadOnly Property IsReceiveOnly As Boolean
Public MustOverride ReadOnly Property IsReceiveOnly As Boolean
Valor de propiedad
true
si la interfaz sólo recibe tráfico de red; de lo contrario, false
.
Excepciones
Esta propiedad no es válida en equipos que ejecutan sistemas operativos anteriores a Windows XP.
Ejemplos
