Please, can someone help me? Thank you

public void SocketSet(bool b, int action_type)
    {
        if (currentState != b)
        {
            if (b && !connected)
            {
                var obj = new JObject();
                obj["room"] = "Bb";
                obj["content"] = "test";
                obj["from"] = "test";
                obj["dir"] = "left";
                obj["avatar"] = "";
                connected = true;
                manualResetEvent = new System.Threading.ManualResetEvent(false);
                var options = CreateOptions();
                socket = IO.Socket("http://localhost:3000", options);

                socket.Emit("new-message", obj);

                socket.Open();
            }
    }
