Thoughts on... "Fetching" a readonly "version" of a object from its editable "version"

juddaman posted on Wednesday, March 28, 2007

Is it appropriate to allow readonly objects to be fetched from a editable object. For example make a PersonInfo from a Person.

        public static PersonInfo GetPersonInfo(Person p)
        {
            return new Person(p);
        }

        private PersonInfo(Person p)
        {
               _Name = p.Name;
        }

Thanks, George.

 oops thats should have been:

        public static PersonInfo GetPersonInfo(Person p)
        {
            return new PersonInfo(p);
        }

        private PersonInfo(Person p)
        {
               _Name = p.Name;
        }

There is no right or wrong way to to do this. In my opinion, I would not use a static method for this. Since you are requiring passing in an instance of Person, I would make GetPersonInfo an instance method that takes no parameters.
