What is the best way to iterate over a dictionary?

Question

I\'ve seen a few different ways to iterate over a dictionary in C#. Is there a standard way?

Answer 1

I wrote an extension to loop over a dictionary.

public static class DictionaryExtension
{
    public static void ForEach(this Dictionary dictionary, Action action) {
        foreach(KeyValuePair keyValue in dictionary) {
            action(keyValue.Key, keyValue.Value);
        }
    }
}

Then you can call

myDictionary.ForEach((x,y) => Console.WriteLine(x + " - " + y));
