class - Clases and Objects in c#

Question

I have the next situation

Generic class:

public class A {
...
}

and two clases:

public class B: A {
...
}

public class C: A {
...
}

In some part of the code I want to do something like (list is filled previously):

foreach (A item in list) {
   listB.add((B) item);
}

Is it possible to do it? I just want to bind the list of generic ítems to the list of clases extends the generic class.

Thanks

Answer 1

You cannot do what you are trying to do because you won't be able to add items of type C to your list of B items

You can however

foreach(B item in list.OfType<B>())
       listB.add(item);
