Inheritance at executing time

[André Nobre]

Hi folks,
I don´t know if this is possible. I want to make a class inheritance while
my program is running, depending on my user´s data.

Can I do this? Any ideas?

Thanks!

Sure, using System.Reflection.Emit you can dynamically create an
assembly and create a new type that inherits from a given type.

Hi,

In theory you can , using Reflection, but may I ask the reason why you want
to do this?

I would guess you want some kind of Factory pattern.

Depending on the type of my user I´ll need to instanciate a class. In my
architeture, I don´t want to use Interfaces in this case (and it won´t have
any meaning if I use it..) and I don´t want to agrupate all atributes from
one type and othes in the same class, and just use a some of them.

This is a common escenario for a Factory pattern. depending of some criteria
you instantiate a different type.

Contrary to your opinion though you should use a common interface. In case
that some types use functionality that others dont you should always ask if
a particular instance implement the expected interface using the "as"
operator.
