With SignalR, is it possible to send only one person or group message?

Question

Many sites, including MSDN, have exemplified sending messages to all clients.

For example; With Clients.All.addNewMessageToPage (), the message goes to all users.

What should be done if I just want to send a message to a group of people who are chatting?

Or to send a message to a single contact ...

Thank you...

Answer 1

yes you can send to group of people by joining group like this

public class ContosoChatHub : Hub
{
    public Task JoinRoom(string roomName)
    {
        return Groups.Add(Context.ConnectionId, roomName);
    }

    public Task LeaveRoom(string roomName)
    {
        return Groups.Remove(Context.ConnectionId, roomName);
    }
}

and send message to this group by

Clients.Group(groupName).addChatMessage(name, message);
