如何不将 class 暴露给任何其他 class 而不是一个？ （C＃）

Question

I have a namespace ABC, which has one form class, F and an ordinary class C. Now I have another namespace XYZ with many different classes. Now, F is used only from C and nowhere else in the program. Every other classes use C, not F.

In visual studio (2010), from classes in XYZ namespace I can see F listed in the intellisense dropdown (since I've referenced ABC to use C). How can I prevent that?I want only C there. Any method would suffice as long as I can use C from XYZ.

Thanks.

Answer 1

Can you make F a nested class inside of your C class?

public class C
{
    public C()
    { }

    class F : Form
    {
        ...
    }
}

I'm not sure if this works for your scenario, but it would solve the Intellisense problem, while satisfying the requirements listed above.

Answer 2

Is there any reason why you can't put it in another namespace to hide it from the other classes, eg namespace ABC.Forms?

If it were anything other than a form class (therefore is a partial class if you are using a recent version of .net) - I would say, why not make it an inner class to C - but I doubt that would be neat with a form class.

I would go with the namespace change.
