C#3.0 Automatic properties with extra logic

Question

How can I rewrite he following code using C#3.0 automatic properties?

private int _myValue;
        public int MyProperty 
        {
            get { return _myValue;}
            set
            {
                if (value > 0)
                {
                    _myValue = value;
                }
            }
        }

If it is not possible, What is the alternative?

Answer 1

Answer: You can't do this with automatic properties.

Answer 2

No, automatically implemented properties have no declared implementation. Any extended implementation that you wish to provide would have to use a regular property.

I am not sure what you are looking for in terms of an alternative - the syntax you have used in your question is the alternative.
