Question

I’m trying to create a class (in C#) that serves as an environment for my application.

I’m trying to make the class dynamic, and send it as a parameter to entities in my application. The problem is, that I want to be able to change the properties of this environment class (public setters), but at the same time I want the classes that receive the environment to be unable to use these setters.

I can’t seem to find a good way to phrase my question (which I figure is a part of the reason I can’t find anything like this on Google or msdn), but to put shortly, I want to create a class with setters that are public only for some of my objects and not for all.

I’m currently amusing the following idea:
Avoiding the public setters all together, and expose the private fields using event registration.

The class will register to events in a new third object (sent as a parameter to the constructor). The methods that will be registered by the environment are not much more then setters, and so triggering these events will “allow access” to the private fields.

I’d love some ideas (seeing as I feel that mine isn’t all that great), or better yet some patterns I could make use of.

Thanks in advance

Answer 1

You could create a proxy, and send that proxy to your entity classes.

class MyClass
{
    public int MyProperty { get; set; }
}

class MyProxyClass
{
    public MyProxyClass(MyClass myClass)
    {
        _myClass = myClass;
    }

    private MyClass _myClass;

    public int MyProperty
    {
        get { return _myClass.MyProperty; }
    }
}
