UdpClient.JoinMulticastGroup Method (IPAddress, IPAddress)
Adds a UdpClient to a multicast group.
Assembly: System (in System.dll)
Before you join a multicast group, be sure that the socket is bound to the port or endpoint. You can do this by calling one of the constructors that accepts a port or an endpoint as parameter.
There are several multicast address ranges to choose from. You can find them in the IETF RFC 2375.
The following code example shows the use of the JoinMulticastGroup method.
Windows 8.1, Windows Server 2012 R2, Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
