Server to Clients or One to Many

[Anonymous]

Hi!
I like your library, but have a problem with it. I would ask you to help me.
I’m developing very nonstandard application. There is one Server and many Clients (I have ~300). I want to send a message from Server to all Clients. The main idea is to close working program on all Client PCs.

For example i have a button in my program “Close my program on all my Clients PCs”. Also I know all Client IPs.

Thanks, and sorry for my English 🙂

I’m not sure what your question is. I can however say that it would be very easy to achieve what you are trying to do with NetworkComms.Net.

Yes, I want to use NetworkComms.Net in my project.
The question is: how can I send a message to all clients?
I know their IPs.
Thanks.

You can either use a UDP broadcast which is the most efficient for a large number of clients:

//Broadcast a shutdown state object to all local network clients
ShutdownState state = new ShutdownState();
NetworkCommsDotNet.Connections.UDP.UDPConnection.SendObject("ClientShutdown", state, new IPEndPoint(IPAddress.Broadcast, 10000));

or using TCP:

List<IPAddress> clientAddresses = new List<IPAddress>() { /* All IPs go here */ };
ShutdownState state = new ShutdownState();

//Connect to each client and send the shutdown packet
foreach (IPAddress address in clientAddresses)
{
    try
    {
        ConnectionInfo clientInfo = new ConnectionInfo(new IPEndPoint(address, 10000));
        NetworkCommsDotNet.Connections.TCP.TCPConnection.GetConnection(clientInfo).SendObject("ClientShutdown", state);
    }
    catch (CommsException)
    {
        Console.WriteLine("Failed to send shutdown to {0}", address.ToString());
    }
}
