	int localPort


Type: System.Net.IPAddress

The sender source address for this receiver to subscribe to.

Type: System.Net.IPAddress

The multicast group address for this receiver to subscribe to.

Type: System.Int32

The local port for this receiver to bind to.

sourceAddress and groupAddress must be the same address family.


sourceAddress is a null reference (Nothing in Visual Basic).


groupAddress is a null reference (Nothing in Visual Basic).


localPort is less than 0

The UdpSingleSourceMulticastClient constructor associates a UDP multicast socket with a group address and port, but does not bind or otherwise use the socket.

The groupAddress parameter may be either an IPv6 or IPv4 multicast address. However, the address family of the sourceAddress and groupAddress parameters must the same.

The localPort parameter must not specify a port less than 1,024.
