REPOST:Hiding base class property from derived class instance

[Baski]

Base class:
class AssetBase
{
string _clli;

public string CLLI
{
get
{
return _clli;
}
set
{
_clli = value
}
}
}
In Derived Class I want to give different name to the base class property
and internally refer the base class property like below
class Asset: BaseAsset
{
public string Location
{
get
{
base.CLLI;
}
set
{
base.CLLI = value;
}
}
}

Now , when the developer use this dll in their project and create Asset
instance I want to hide the AssetBase Property CLLI , all i want to see them
is Location. I can do this by making base class properties to protected ,
but I want some of the property to be exposed to the developer
as it's defined in base class. How can I do that ?
Thanks

Please give a brief example that illustrates what you really want to do. In
the example you give, there is no reason to hide the base property with
another, since it is exactly the same as the derived one, and also nothing
the developer could possibly want to use in the base that is not exposed by
the derived property.

If you can give us an understanding of what you really want to do, we very
likely can suggest a solution for your problem.

Rachel,

I have base framework , which will be used for multiple clients , each
client will call the properties in different names. Base class will not be
used by the developer any where. We are using the inheritance to get most
functionality(r eusability) from base class and easily adopt the new client
with simple name customization.

If the base class properties is not renamed in the derived class , I want
the developer to see as it's defined in base class from derived class
instance variable.

If you need more explanation, plese feel free to email me.

Thanks

Ah, now I understand.

When you rename the properties, do you need the originals to be unusable by
the user/developer, or do you just want them not to show up in the
"properties " window of the designer?

If any properties is renamed in derived class I want to mask that
propoerty from developer derived class instance(just like Explicit interface
implementation hide).

It sounds like you want to use an interface instead of inheritance.

If you have public properties in a base class, you won't be able to mask
them in inherited classes. The reason for this is simple.

We'll say that you have object X, we'll call it a ListBox, but you need
to use it with object Y, which only takes WebControls. If X hid members
of the WebControls class, it would no longer be considered a WebControl,
and wouldn't work with object Y.

An interface of common properties will be easier for you to control.
Let those properties be the external items that the dev's work with, but
keep everything else internal.

Essentially, you can't rename properties in child classes, because then
those classes would no longer be children.

Well, then I don't think you can get that for free. I think you will have to
give it a protected modifier in the base class, and add a public property of
the same name in the derived class, if you want that property available.
Something like this:

// Base class protected property
protected string LabelText
{
get { return label.Text; }
set { label.Text = value;}
}

// Derived class hides it with a public property
public new string LabelText
{
get{return base.LabelText; }
set{base.LabelT ext = value;}
}

So you copy/paste the 2nd property into each derived class that doesn't
actually have a rename.

Oh, I just tried the opposite, and it did compile....

What I mean is having a public property in the base class, and then hiding
it ...
------------------
protected new string CCLI...
------------------------

I haven't tried to actually use something like that, though. I'd be leery of
taking away from the public signature of a base class in a derived class,
although I can see where it might make sense if the base class is
abstract... As long as it's clear that the base class's public property
isn't really part of the type's interface (ahh... ?!?)
