C# in a Nutshell

Name

UdpClient

Synopsis

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 JoinMulticastGroup() method sets the address of an IP-multicast group to join. DropMulticastGroup() drops the client from the group.
