C# - How to implement IEnumerator on a class

Question

How to implement IEnumerator on this class so that I can use it in foreach loop.

public class Items
    {
        private Dictionary

        

Answer 1

You should be able to implement IEnumerator like this:

public class Items : IEnumerator>  
{        
    private Dictionary _items = new Dictionary();        
    public Configuration this[string element]       
    {            
        get
        {
            if (_items.ContainsKey(element))
            {
                return _items[element];
            }
            else
            {
                return null;
            }
        }
        set
        {
             _items[element] = value;
        }
    }

    int current;
    public object Current
    {
        get { return _items.ElementAt(current); }
    }

    public bool MoveNext()
    {
        if (_items.Count == 0 || _items.Count <= current)
        {
            return false;
        }
        return true;
    }

    public void Reset()
    {
        current = 0;
    }

    public IEnumerator GetEnumerator()
    {
        return _items.GetEnumerator();
    }

    KeyValuePair IEnumerator>.Current
    {
        get { return _items.ElementAt(current); }
    }

    public void Dispose()
    {
        //Dispose here
    }
}

But as already noted you could also just implement IEnumerable.
