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

c#, dictionary, generics, list

Solution

You can simply return the enumerator returned by List<T>.GetEnumerator:

public class AlbumList : IEnumerable<Album>
{
    // ...

    public IEnumerator<Album> GetEnumerator()
    {
        return this.albums.GetEnumerator();
    }

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

Problem

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 wrapper around a data structure (in this case a list, but I might need a dictionary later) and add some functions. ``` public class Album { public readonly string Artist; public readonly string Title; public Album(string artist, string title) { Artist = artist; Title = title; } } public class AlbumList { private List<Album> Albums = new List<Album>; public Count { get { return Albums.Count; } } ..... //Somehow GetEnumerator here to return Album } ``` Thanks!
