How to have an Iterator for a Dictionary?

Question

I have a Class that uses a dictionary to store some data.

But I want to hide that implementation detail from the outside, to iterate all my data I would like to send an iterator to the ouside of my class

how can I do this?

Answer 1

public IEnumerable<KeyValuePair<int, string>> Foo()
{
    var implementationDetail = new Dictionary<int, string>
    {
        { 1, "foo" },
        { 2, "bar" },
    };

    return implementationDetail;
}

Answer 2

You may call the Dictinary.GetEnumerator() that returns an enumerator.
