C# getter and setter shorthand

Question

If my understanding of the internal workings of this line is correct:

public int MyInt { get; set; }

Then it behind the scenes does this:

Answer 1

I'm going to add on to Simon Hughes' answer. I propose the same thing, but add a way to allow the decorator class to update a global IsDirty flag automatically. You may find it to be less complex to do it the old-fashioned way, but it depends on how many properties you're exposing and how many classes will require the same functionality.

public class IsDirtyDecorator
{
    private T _myValue;
    private Action _changedAction;

    public IsDirtyDecorator(Action changedAction = null)
    {
        _changedAction = changedAction;
    }

    public bool IsDirty { get; private set; }

    public T Value
    {
        get { return _myValue; }
        set
        {
            _myValue = value;
            IsDirty = true;
            if(_changedAction != null)
                _changedAction(IsDirty);
        }
    }
}

Now you can have your decorator class automatically update some other IsDirty property in another class:

class MyObject
{
    private IsDirtyDecorator _myInt = new IsDirtyDecorator(onValueChanged);
    private IsDirtyDecorator _myOtherInt = new IsDirtyDecorator(onValueChanged);

    public bool IsDirty { get; private set; }

    public int MyInt
    {
        get { return _myInt.Value; }
        set { _myInt.Value = value; }
    }

    public int MyOtherInt
    {
        get { return _myOtherInt.Value; }
        set { _myOtherInt.Value = value; }
    }

    private void onValueChanged(bool dirty)
    {
        IsDirty = true;
    }

}
