UdpClient
This class is used to create UDP
client sockets. UDP-based clients
transmit messages called datagrams across a connection. Unlike TCP,
control data is not sent to ensure the integrity and order of the
data (so UDP is faster than TCP, but not as reliable). UDP is often
used to broadcast media streams, such as video, and to support
multicasting. The UdpClient can be constructed
with a binding to a local address and port, or it can be constructed
given the IP address and port number of the remote server to which it
connects.
The JoinMulitcastGroup( ) method sets the addres of
an IP-multicast group to join.
DropMulticastGroup( ) drops the client from the
group.
