C#: IEnumerable, GetEnumerator, a simple, simple example please!

Question

Trying to create an uebersimple class that implements get enumerator, but failing madly due to lack of simple / non-functioning examples out there. All I want to do is create a

Answer 1

using System.Collections;
using System.Collections.Generic;

public class AlbumList : IEnumerable
{
    private List Albums = new List();

    public int Count { get { return Albums.Count; } }

    public IEnumerator GetEnumerator()
    {
        return this.Albums.GetEnumerator();
    }

    IEnumerator IEnumerable.GetEnumerator()
    {
        return this.GetEnumerator();
    }
}

or the simplified version:

public class AlbumList
{
    private List Albums = new List();

    public int Count { get { return Albums.Count; } }

    public IEnumerator GetEnumerator()
    {
        return this.Albums.GetEnumerator();
    }
}

I wouldn't advice leaving out the IEnumerable interface, because you loose integration with .NET such as possibilities to use LINQ, but you can iterate over the collection using a foreach in C#.

Or this one is even shorter :-)

public class AlbumList : List
{
}

Of course this last one is a mutable list, which perhaps is not exactly what you want.
