public class MulticastOption

Thread Safety

All public static members of this type are safe for multithreaded operations. No instance members are guaranteed to be thread safe.

Remarks

Collectively, the hosts listening to a specific IP multicast address (the group address) are called a multicast group. Each member of the group receives any IP messages sent to the group address.

An instance of this class is passed into the Socket.SetSocketOption(SocketOptionLevel, SocketOptionName, int) method and returned by the Socket.GetSocketOption(SocketOptionLevel, SocketOptionName) method when the optionName parameter is set to SocketOptionName.AddMembership or SocketOptionName.DropMembership.
