I am trying this code for multiple chat rooms like stackoverflow, but my code working for only one chat room group
Code is here shown:
div id="header">
SignalR Chat Room
multiple group chat rooms in asp.net using SignalR
Your Name:
Welcome to Chat Room []
JavaScript Code:
Hide Expand Copy Code
SignalR C# Code:
Hide Expand Copy Code
public class ChatHub : Hub
{
#region List of Data Member
static List ConnectedUsers = new List();
static List CurrentMessage = new List();
#endregion
#region Send, recieve and broadcast message methods
public void Connect(string userName)
{
// To get the clients connected connection ID's
var id = Context.ConnectionId;
if (ConnectedUsers.Count(x => x.ConnectionId == id) == 0)
{
ConnectedUsers.Add(new UserDetail { ConnectionId = id, UserName = userName });
// send to caller
Clients.Caller.onConnected(id, userName, ConnectedUsers, CurrentMessage);
// send to all except caller client
Clients.AllExcept(id).onNewUserConnected(id, userName);
}
}
// To send message to all the connected clients
public void SendMessageToAll(string userName, string message)
{
// store last 100 messages in cache
AddMessageinCache(userName, message);
// Broad cast message
Clients.All.messageReceived(userName, message);
}
public void SendPrivateMessage(string toUserId, string message)
{
string fromUserId = Context.ConnectionId;
var toUser = ConnectedUsers.FirstOrDefault(x => x.ConnectionId == toUserId);
var fromUser = ConnectedUsers.FirstOrDefault(x => x.ConnectionId == fromUserId);
if (toUser != null && fromUser != null)
{
// send to
Clients.Client(toUserId).sendPrivateMessage(fromUserId, fromUser.UserName, message);
// send to caller user
Clients.Caller.sendPrivateMessage(toUserId, fromUser.UserName, message);
}
}
public override System.Threading.Tasks.Task OnDisconnected()
{
var item = ConnectedUsers.FirstOrDefault(x => x.ConnectionId == Context.ConnectionId);
if (item != null)
{
ConnectedUsers.Remove(item);
var id = Context.ConnectionId;
Clients.All.onUserDisconnected(id, item.UserName);
}
return base.OnDisconnected();
}
#endregion
#region private Messages send to individual
private void AddMessageinCache(string userName, string message)
{
CurrentMessage.Add(new MessageDetail { UserName = userName, Message = message });
if (CurrentMessage.Count > 100)
CurrentMessage.RemoveAt(0);
}
#endregion
}
Two Other Classes:

public class MessageDetail
{
public string UserName { get; set; }
public string Message { get; set; }
}
Hide Copy Code
public class UserDetail
{
public string ConnectionId { get; set; }
public string UserName { get; set; }
}
Please any one tell me right solution to implement chat server like stackoverflow.
