NetworkInterface.SupportsMulticast Propiedad

Definición

Obtiene un valor Boolean que indica si la interfaz de red está habilitada para recibir paquetes de multidifusión.

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

Valor de propiedad

true si la interfaz recibe paquetes de multidifusión; de lo contrario, false.

Excepciones

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.

public static void DisplayTypeAndAddress()
{
    IPGlobalProperties computerProperties = IPGlobalProperties.GetIPGlobalProperties();
    NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
    Console.WriteLine("Interface information for {0}.{1}     ",
            computerProperties.HostName, computerProperties.DomainName);
    foreach (NetworkInterface adapter in nics)
    {
        IPInterfaceProperties properties = adapter.GetIPProperties();
        Console.WriteLine(adapter.Description);
        Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length,'='));
        Console.WriteLine("  Interface type .......................... : {0}", adapter.NetworkInterfaceType);
        Console.WriteLine("  Physical Address ........................ : {0}",
                   adapter.GetPhysicalAddress().ToString());
        Console.WriteLine("  Is receive only.......................... : {0}", adapter.IsReceiveOnly);
        Console.WriteLine("  Multicast................................ : {0}", adapter.SupportsMulticast);
        Console.WriteLine();
      }
   }
Public Shared Sub DisplayTypeAndAddress() 
    Dim computerProperties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim nics As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
    Console.WriteLine("Interface information for {0}.{1}     ", computerProperties.HostName, computerProperties.DomainName)
    Dim adapter As NetworkInterface
    For Each adapter In  nics
        Dim properties As IPInterfaceProperties = adapter.GetIPProperties()
        Console.WriteLine(adapter.Description)
        Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length, "="c))
        Console.WriteLine("  Interface type .......................... : {0}", adapter.NetworkInterfaceType)
        Console.WriteLine("  Physical Address ........................ : {0}", adapter.GetPhysicalAddress().ToString())
        Console.WriteLine("  Is receive only.......................... : {0}", adapter.IsReceiveOnly)
        Console.WriteLine("  Multicast................................ : {0}", adapter.SupportsMulticast)
    Next adapter

End Sub

La multidifusión es el acto de enviar un paquete de datos a varios destinos simultáneamente.
