I am developing a chat in Signalir, and I can only send messages to all logged in Users, using this way:
public void Send(string name, string message)
{
Clients.All.broadcastMessage(name, message);
}
I would like to send to a specific user, how can I do this ?

To send a specific user or users, you need to map user to connection. There are 4 ways you can do this, among them are:
I’ll give you a basic example of mapping connection using In-memory:
public class ChatHub : Hub
{
private readonly static ConnectionMapping<string> _connections =
new ConnectionMapping<string>();
public void Send(string who, string message)
{
string name = Context.User.Identity.Name;
foreach (var connectionId in _connections.GetConnections(who))
{
Clients.Client(connectionId).addChatMessage(name + ": " + message);
}
}
public override Task OnConnected()
{
//é executado quando a conexão se conecta a esta instância do hub.
}
public override Task OnDisconnected(bool stopCalled)
{
//é executado quando uma conexão se desconecta desta instância do hub.
}
public override Task OnReconnected()
{
//é executado quando uma conexão de transporte é automaticamente restabelecida depois de ter sido perdida.
}
}

It didn’t work out here, it’s possible I could use the
$.connection.hub.idfor that reason?– Andre Neto

@Andreneto, for you to send a specific user, need to map the user’s connection. Please look at the answer. Anything let me know.
