MulticastIPAddressInformationCollection

En MulticastIPAddressInformationCollection som innehåller multicast-adresserna för det här gränssnittet.

Exempel

I följande kodexempel visas multicast-adresserna för nätverksgränssnitten på den lokala datorn.

public static void DisplayMulticastAddresses()
{
    int count = 0;

    Console.WriteLine("Multicast Addresses");
    NetworkInterface[] adapters  = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in adapters)
    {
        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
        MulticastIPAddressInformationCollection multiCast = adapterProperties.MulticastAddresses;
        if (multiCast.Count > 0)

Kommentarer

En multicast-adress identifierar flera datorer. Paket som skickas till en multicast-adress skickas till alla datorer som identifieras av adressen.
