Is it possible to hide a method from inheriting from a parent class ?

[nirmallyakoley]

Suppose I have a class

class A
  {
    public void Foo()
    {
 
     }
}

i want to inherit A to class B & C

class B:A
  {
 
  }
 
class C:A
{
 
}

How can I write the class A so that I can access Foo() by object of class B but by C object Foo() will be unavailable.Is it possible?.

TIP: When you are writing your question, there is a button on the tool bar that wraps the [code] tags around your copy/pasted code. It helps a bunch. Its the button with a '#' on it. More on tags. They're cool. Check'em out.

I don't think you can do what you want. I think the best you can hope for is to make the class a sealed class so that it can't be inherited. Here, have a look at this link, hopefully it explains things better than I can, inheritance has never been a strong suit of mine.

Dear Gary,
Thank you so much for your kind respone.

Quote MSDN:

The sealed modifier can be applied to classes, instance methods and properties. A sealed class cannot be inherited. A sealed method overrides a method in a base class, but itself cannot be overridden further in any derived class. When applied to a method or property, the sealed modifier must always be used with override (C# Reference).

Says you can seal an individual method, which might work for you.


Your other option might be to mark things internal. Which means only classes in the same assembly can use it. So if you are say compiling a DLL with a base class and a class deriving from it. Only the deriving classes in your DLL can use the function. At least that's how I've come to understand it.

This is why I love this forum, you learn something new almost every day. Nice work, Plater! :)
