NetworkInterface.IsReceiveOnly Propiedad

Definición

Espacio de nombres:

System.Net.NetworkInformation

Ensamblado:

System.Net.NetworkInformation.dll

Source:

NetworkInterface.cs

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 virtual bool IsReceiveOnly { get; }

member this.IsReceiveOnly : bool

Public Overridable ReadOnly Property IsReceiveOnly As Boolean

Valor de propiedad

Boolean

true si la interfaz sólo recibe tráfico de red; de lo contrario, false.

Excepciones

PlatformNotSupportedException

Esta propiedad no es válida en equipos que ejecutan sistemas operativos anteriores a Windows XP.

Ejemplos

En el ejemplo de código siguiente se muestra un resumen de todas las interfaces del equipo local.
