事件通过C＃属性发布和订阅

Question

Can we do event publish and subscription through C# attributes being specified on Method or property??

If Property is changed .. then we need to fire a event...
[FirePropertyChangedEvent] SomeProperty

I've answered a similar question to this one, so ill copy my answer:

lets say you are using a local "speed" variable, which you want updated every time the main "speed" variable is updated...

public class SpeedHolder
{
    private float _speed;

    public event Action<float> OnSpeedChange;

    public float Speed
    {
        get { return _speed; }
        set { SetSpeed(value); }
    }

    public SetSpeed(float value)
    {
        _speed = value;
        if(OnSpeedChange != null)
            OnSpeedChange(_speed);
    }
}

now in every 'constructor' method of every script which uses a speed float variable, you need to add this line: SpeedHolder.OnSpeedChange += ChangeSpeed; and have a method like this one:

public void ChangeSpeed(value)
{
    speed = value;
}
