I will give you my thoughts on the issue. Firstly by Enumerator I am guessing you mean the primitive enum type. If you actually mean Enumerators in the enumerating over a collection sense then my answer would differ. The big difference between dictionary and enum is that enum is a primitive type which is very simple to create declare and work with. When talking about Dictionary  there is no actual Dictionary type. However there are classes which implement the IDictionary interface. For example the HashTable implements IDictionary  as it is a nongeneric collection of key/value pairs. SortedList also implements IDictionary . So basically if you need to create a collection which uses key/value pairs implementing IDictionary would be the way to go. However if you just want a quick and dirty enumerated list which provides a finite list of options to choose from the enum is more appropriate.
