Hello Ravi, Please store the user Detail in DataBase specially ID which is generated by HUB, with respective Users..

 

 

And Check each time while user login the application..

 

 

public void Connect(string userName)
        {
            var id = Context.ConnectionId;

            // Getting ID from DataBase if Exist
            string LoginId = ConnC.GetColumnVal("Select LoginId from Users Where UserName='" + userName + "'", "LoginId");

            if (LoginId == null || LoginId != "") // Updating ID in DataBase if Not Exist
                ConnC.ExecuteQuery("Update Users set LoginId='"+ id + "' where UserName='" + userName + "'");

            if (ConnectedUsers.Count(x => x.ConnectionId == id) == 0)
            {
                string UserImg = GetUserImage(userName);
                string logintime = DateTime.Now.ToString();

                if (LoginId != id)
                    ConnectedUsers.Add(new Users { ConnectionId = id, UserName = userName, UserImage = UserImg, LoginTime = logintime });
                // send to caller
                Clients.Caller.onConnected(id, userName, ConnectedUsers, CurrentMessage);

                // send to all except caller client

                    Clients.AllExcept(id).onNewUserConnected(id, userName, UserImg, logintime);
            }
        }
