UdpClient.MulticastLoopback Property

Gets or sets a Boolean value that specifies whether outgoing multicast packets are delivered to the sending application.

Namespace:  System.Net.Sockets
Assembly:  System (in System.dll)

public bool MulticastLoopback { get; set; }

Property Value

Type: System.Boolean
true if the UdpClient receives outgoing multicast packets; otherwise, false.

Multicast is a scalable method for many-to-many communication on the Internet. If a process subscribes to a multicast address, any packets sent by that process are received by every other process that has subscribed to the multicast address.

The following code example shows the use of the MulticastLoopback property.

public static void GetSetMulticastLoopback(UdpClient u)
{
    // Deliver multicast packets back to the sending client.
    u.MulticastLoopback = true;
    Console.WriteLine("MulticastLoopback value is {0}",
        u.MulticastLoopback);
}
static void GetSetMulticastLoopback(UdpClient* u)
{
    // Deliver multicast packets back to the sending client.
    u->MulticastLoopback = true;
    Console::WriteLine("MulticastLoopback value is {0}",
        __box(u->MulticastLoopback));
}
