How do I implement IEnumerable in my Dictionary wrapper class that implements IEnumerable?

Dictionary implements IEnumerable

Answer 1

You've already had several answers to your main question. I'll answer the question raised in your edit...

The List class actually has three different GetEnumerator methods: The public method that's called when the compile-time instance is typed as List itself, and two explicit interface implementations to meet the IEnumerable/IEnumerable contracts. The enumerator objects returned by all three methods are all the same List.Enumerator type behind-the-scenes.

// Public method
public List.Enumerator GetEnumerator() { /* ... */ }

// IEnumerable explicit interface implementation
IEnumerator IEnumerable.GetEnumerator() { /* ... */ }

// IEnumerable explicit interface implementation
IEnumerator IEnumerable.GetEnumerator() { /* ... */ }
