Blocks a source so that multicast packets originating from it are no longer received.
Assembly: System.Net (in System.Net.dll)
The method blocks multicast packets originating from a specified source address from being received. The client must have completed a join to the multicast group.
The sourceAddress parameter may be either an IPv6 or IPv4 address, but the sourceAddress parameter must match the address family of the multicast group that the client joined.
