UdpAnySourceMulticastClient Class

A client receiver for multicast traffic from any source, also known as Any Source Multicast (ASM) or Internet Standard Multicast (ISM).

System.Object
  System.Net.Sockets.UdpAnySourceMulticastClient

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

public class UdpAnySourceMulticastClient : IDisposable

The UdpAnySourceMulticastClient type exposes the following members.

  NameDescription
Public methodUdpAnySourceMulticastClientCreates a new UdpAnySourceMulticastClient UDP client that can subscribe to a group address and receive datagrams from any source.
Top

  NameDescription
Public propertyMulticastLoopbackGets or sets a value that specifies whether outgoing multicast packets are delivered to the sending application.
Public propertyReceiveBufferSizeGets or sets the size, in bytes, of the receive buffer of the Socket used for multicast receive operations on this UdpAnySourceMulticastClient instance.
Public propertySendBufferSizeGets or sets the size, in bytes, of the send buffer of the Socket used for multicast send operations on this UdpAnySourceMulticastClient instance.
Top

  NameDescription
Public methodBeginJoinGroupBinds the socket and begins a join operation to the multicast group to allow datagrams to be received from any group participant.
Public methodBeginReceiveFromGroupBegins the operation of receiving a packet from the joined multicast group and invokes the specified callback when a packet has arrived on the group from any sender.
Public methodBeginSendToBegins the operation of sending a unicast packet to the specified destination.
Public methodBeginSendToGroupBegins the operation of sending a packet to a joined multicast group and invokes the specified callback when a packet has been sent to the group.
Public methodBlockSourceBlocks a source so that multicast packets originating from it are no longer received.
Public methodDisposeLeaves the multicast group and releases all resources used by the current instance of the UdpAnySourceMulticastClient class and the underlying Socket.
Public methodEndJoinGroupCompletes the asynchronous join group operation to a multicast group.
Public methodEndReceiveFromGroupCompletes the asynchronous operation of receiving a packet from the joined multicast group and provides the information received.
Public methodEndSendToCompletes the operation of sending a unicast packet to the specified destination.
Public methodEndSendToGroupCompletes the operation of sending a packet to a multicast group.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeReleases the resources held by the current UdpAnySourceMulticastClient class. (Overrides Object.Finalize().)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodUnblockSourceUnblocks a source that was previously blocked by a call to the BlockSource method so that multicast packets originating from it can be received.

The multicast group address must be known, but any group participant may send to the group. Sending sources may be discovered by examining the address of packets received from calls to the BeginReceiveFromGroup method. The source address of the sender is returned by the EndReceiveFromGroup method. These characteristics make any source multicast useful for peer discovery and peer to peer communication.

In addition to sending multicast data to and receiving multicast data from the multicast group, the client can also send unicast data to sources it has received multicast data from. This allows for directed messaging and is useful for protocols which need to pass quality of service or control information back to a source.

To receive multicast from a single source where the address is known in advance, such as in broadcast and content delivery scenarios, see the UdpSingleSourceMulticastClient class.
