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

Question

I\'m trying to create a wrapper for a Dictionary.

Dictionary implements IEnumerable

Answer 1

Here's the declaration of IEnumerable:

public interface IEnumerable : IEnumerable
{
    new IEnumerator GetEnumerator();
}

notice the new keyword.

Here's the declaration of IEnumerable:

public interface IEnumerable
{

    IEnumerator GetEnumerator();
}

So now you have a GetEnumerator method, but which one of those two are you implementing? Therefore, you need to add an explicit implementation of the non-generic version:

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