how to get a socket ID after connecting

HI, im using https://github.com/mattleibow/Socket.IO.Client . how i can get socketID after connection is successfull? is there any other socket through which i can get the desired result.

here is my code:

var socket = IO.Socket("http://10.175.8.65:1337/");
socket.Connect();

        socket.On("new_message", data =>
        {
            Device.BeginInvokeOnMainThread(() =>
            {

                var jobject = data as JObject;

                var geo = JsonConvert.DeserializeObject<MessageData>(jobject.ToString());
                bool from;
                bool to;

                items.Add(new MessageData { user_id = geo.user_id, message = geo.message, user_name = geo.user_name });

            });
        });
