Extend a base class during runtime

[Guest]

Hi,

I have two classes, a base clase ItemType and a class which inherits from it
called Item. During the runtime of my program, I create an instance of
ItemType, then later, I would like to extend it into an object of class Item.
What is the best practice to extend the base class object into a class that
inherits from it?

Thanks,

James

You can accomplish this by using CodeDOM.
But why on earth would you want to do such a thing? Do you hate maintainers?

Similar question, and a "How" for Michael,

Using the strong typed dataset generator - instead of the generator
producing code from the xml schema file, and that code being used within the
VStudio IDE (intelisense, compiler etc), would it be possible to have a base
class which emitted nested methods based on the contents of the xml file
(without producing the intermediate code).

For example: I select the "MySchema" data control and drop it on my form. On
the property grid of 'MySchema' I enter a path to an xml file, this file is
read when the property is set. 'MySchema' then emits a new set of methods
that can be detected by the VStudio intelisence and by the compiler (this is
the tricky part).

Hello

class Item : ItemType
{

...

public Item(ItemType it)
{
// do something
}

...

}

ItemType it = new ItemType();
Item i = new Item(it);
