Syntax

'Declaration
Public Class UdpSingleSourceMulticastClient _
    Implements IDisposable

public class UdpSingleSourceMulticastClient : IDisposable

The UdpSingleSourceMulticastClient type exposes the following members.

Constructors

	Name	Description
	UdpSingleSourceMulticastClient	Creates a new UdpSingleSourceMulticastClient UDP client that can subscribe to a group address and receive datagrams from a single source.

Properties

	Name	Description
	ReceiveBufferSize	Gets or sets the size, in bytes, of the receive buffer of the Socket used for multicast receive operations on this UdpSingleSourceMulticastClient instance.
	SendBufferSize	Gets or sets the size, in bytes, of the send buffer of the Socket used for multicast send operations on this UdpSingleSourceMulticastClient instance.

Methods

	Name	Description
	BeginJoinGroup	Binds the socket and begins a join operation to the multicast group to allow datagrams to be received from a single source address.
	BeginReceiveFromSource	Begins 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 a specified sender.
	BeginSendToSource	Begins the operation of sending a unicast packet to the source previously specified.
	Dispose	Leaves the multicast group and releases all resources used by the current instance of the UdpSingleSourceMulticastClient class and the underlying Socket.
	EndJoinGroup	Completes the asynchronous join group operation to a multicast group.
	EndReceiveFromSource	Completes the asynchronous operation of receiving a packet from the joined multicast group and provides the information received from a specified sender.
	EndSendToSource	Completes the operation of sending a unicast packet to a single source.
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) In Silverlight for Windows Phone, this member is overridden by Finalize().
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

The multicast group address and sender source address must be known.

In addition to receiving multicast data from a specific sender, the UdpSingleSourceMulticastClient client can also send unicast data back to the sender.

To receive multicast from multiple sources, or when the sources aren't known in advance, use the UdpAnySourceMulticastClient class instead.
