Re: Can I cast a generic list, or do I need another approach

I have an abstract class Domain which is responsible for validation of my
model. All classes in the model inherit from Domain for operations such as
bool IsValid {get;}.

<snip>

However List<Addressand List<PhoneNumberdoes not cast to List<Domain>..
Is there a way to do this, or are there any other options other than
repeating the code?

Yes, there's a way to do it - you need to make the method generic:

public bool IsChildListValid<T>(List<TdomainList) where T : Domain
{
...
}

That should work with no problems.

Thanks, just what I was after.
