NetworkInterface.SupportsMulticast Eigenschap

Definitie

Naamruimte:
System.Net.NetworkInformation
Assembly:
System.dll
Assembly:
netstandard.dll

Hiermee wordt een Boolean waarde opgehaald die aangeeft of de netwerkinterface is ingeschakeld voor het ontvangen van multicastpakketten.

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

Waarde van eigenschap

Boolean

true als de interface multicastpakketten ontvangt; anders, false.

Uitzonderingen

PlatformNotSupportedException

Deze eigenschap is niet geldig op computers met besturingssystemen die ouder zijn dan Windows XP.

Voorbeelden

In het volgende codevoorbeeld wordt een samenvatting weergegeven voor alle interfaces op de lokale computer.

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

Opmerkingen

Multicasting is het verzenden van een gegevenspakket naar meerdere bestemmingen tegelijk.
