后台内部发送到指定客户端

Microsoft.AspNet.SignalR.GlobalHost.ConnectionManager.GetHubContext<tvHub>().Clients.Client(Client.Key).sendMessage(UserHandler.dicGoods[roomid]);

　　

 var lst = UserHandler.getRoomInfoListByRoomID(roomid);
                    foreach (var Client in lst)
                    {
                        //GlobalHost.ConnectionManager.GetHubContext<tvHub>().Clients
                        GlobalHost.ConnectionManager.GetHubContext<tvHub>().Clients.Client(Client.Key).sendMessage(UserHandler.dicGoods[roomid]);
                        //Clients.Client(Client.Key).sendMessage(UserHandler.dicGoods[roomid]);
                    }

链接绑定用户ID

  //声明静态变量存储当前在线用户
    public static class UserHandler
    {
        public static Dictionary<string, SNInfo> ConnectedIds = new Dictionary<string, SNInfo>();
    }

     //用户进入页面时执行的（连接操作）
        public void controllerConnected(string sn, string guid)
        {
            //进行编码，防止XSS攻击
            sn = HttpUtility.HtmlEncode(sn);

            //新增目前使用者上线清单
            UserHandler.ConnectedIds.Add(Context.ConnectionId, new SNInfo(sn, guid));
        }
