摘　　要：与单播技术相比,IP组播技术可以更有效地传输数据、降低网络负载,因而在视频、音频等多媒体数据传输中有着广泛的应用。C#是NET平台的代表性开发语言,利用C#实现组播有很好的应用前景。IP组播基于UDP协议,在C#开发语言中,可以通过UdpClient类的相关属性和方法来实现加入、退出组和传输组播数据。通过针对UdpClient类进行编程,并结合实际应用,一个基于局域网的组播实例被给出。Compared with Unicast technology, the IP Multicast technology can transmit data more effectively and reduce the network load. Therefore it has wide application in video, audio and other multimedia data transmission. C# is the representative language of NET platform and there is good application prospects in implementation of Multicast using C#. IP Multicast is based on UDP protocol. In the C # programming environment ,jioning in and quiting a group and the transmission of Multicast data can he implemented easily. By using the UdpClient class of the C # programming environment,a practical program on IP multicast within LAN is provided.
