Question

I have been delved in C++ world for a while, but now I’m in .NET world again, VB and C# and I wondered if you have a class that represents a collection of something, and you want the ability to use this in a foreach loop, etc… is it better to implement IEnumerable and IEnumerator yourself or should you inherit from the List<T> where T is the object type in it’s singular form?

I know in C++ for example, inheriting from a container is considered a bad idea.

But what about .NET.

EDIT:

It seems my question was slightly misunderstood. I am not unhappy at all with existing collections in .NET. Here is my problem, I have a class called ‘Person’ and I need a collection called ‘Scouts’, which I want in an Class called ‘Scouts’, at this point I’d like to be able to write

foreach Person in Scouts …

What is the best way to get this Scouts as a collection of People, and be able to use it in a foreach loop?

You said:

I have a class called ‘Person’ and I
need a collection called ‘Scouts’,
which I want in an Class called
‘Scouts’, at this point I’d like to be
able to write

foreach Person in Scouts ...

If I understand you correctly, you want:

class Scouts : IEnumerable<Person>
{
    private List<Person> scouts;

    public IEnumerator<Person> GetEnumerator()
    {
        return scouts.GetEnumerator();
    }
}
