asp.net-mvc get a dictionary in post action or how to transform FormCollection into a dictionary

This is just an equivalent of Omnu's code, but it seems more elegant to me:

Dictionary<string, string> form = formCollection.AllKeys.ToDictionary(k => k, v => formCollection[v]);

I did it like this:

            var form = new Dictionary<string, string>();
            foreach (var key in formCollection.AllKeys)
            {
                var value = formCollection[key];
                form.Add(key, value);
            }
