Hide base mambers in an inherited class

Hi all,

I'm trying to hide a member from a base class, like so :
public class class1
{
public class1()
{
}
public int i;
}

public class class2 : class1
{
public class2()
{
}
private new int i;
}

This article :
http://msdn.microsoft.com/library/de...ec_3_7_1_2.asp
, like others, states that now, class2 shouldn't have a property i.

Unfortunatelly, it still does.

My goal eventually is to create a custom user control inherited from
CustomValidator that doen not has a ServerValidate event.

Any ideas on how you cab hide properties and events?,
Greetz,

Actually, it doesn't - it doesn't have any properties. It still has a
publically available i variable, however.

Name hiding doesn't actually make anything unavailable, it just changes
how you have to access the member in question.

CustomValidator that doen not has a ServerValidate event.


You won't be able to do that, and a good job too - it would break the
Liskov Substitutabilit y Rule. It sounds like you might want to
encapsulate CustomValidator instead of inheriting from it.

Hi Jon,

Thanx for answering!
I understand what u mean, so I'll just leave the ServerValidate event
available for my users!

When I find the inherited class marker, can I...

Suppose I have a base class "foo". Another class, "bar" derives from it. Base class "foo" has a method called "rob_the_liquor_store()", and the inherited class "bar" overrides this method with one of its own, maybe specifying the liquor store over on 44th Street and 5th Avenue or something. Anyway this is what we have so far: base class:...
