NetworkInterface.SupportsMulticast NetworkInterface.SupportsMulticast NetworkInterface.SupportsMulticast NetworkInterface.SupportsMulticast Property

Definizione

Ottiene il valore Boolean che indica se nell'interfaccia di rete è attivata la ricezione di pacchetti multicast.Gets a Boolean value that indicates whether the network interface is enabled to receive multicast packets.

public:
 abstract property bool SupportsMulticast { bool get(); };
public abstract bool SupportsMulticast { get; }
member this.SupportsMulticast : bool
Public MustOverride ReadOnly Property SupportsMulticast As Boolean

Valore della proprietà

true se l'interfaccia riceve pacchetti multicast; in caso contrario, false.true if the interface receives multicast packets; otherwise, false.

Eccezioni

Questa proprietà non è valida su computer che eseguono sistemi operativi precedenti a Windows XP.This property is not valid on computers running operating systems earlier than Windows XP.

Commenti

Il multicast è l'operazione di invio di un pacchetto di dati a più destinazioni simultaneamente.Multicasting is the act of sending a data packet to multiple destinations simultaneously.
