What is the best way to access properties from the same class, via accessors or directly?

I am still learning C#. Anyway I have a simple question but I am unsure the normal way to do this. Say I have the following in a class

private int _questionNo;

public int QuestionNo

    {
        get
        {
            return _questionNo;
        }

        private set
        {
            _questionNo = value;
            PropChanged("QuestionNo");
        }

    }

If I want to set the property within the class itself should I use

_questionNo = number;

or

QuestionNo = number;

You should always use the Public getter-setter, and should NEVER touch the private backing field away from inside the Getter-Setter, unless of course you don’t want the events inside of the Setter to occur.

QuestionNo = number;

The reason for this is that if you ever need to change something in the Setter that you want to happen you won’t have to change all your variables.
