c# - Specifying what network interface an UDP multicast should go to in .NET -


The application of another machine running the same machine with a crossover cable on both computers with an active wireless card and a LAN port, We need to send UDP multicast to LAN Wire on another computer. Using C # sockets, Windows tries to route the message to the WLAN adapter every time.
