I would like to know if 'theObject' is an enum (of any enum type)

 foreach (var item in Enum.GetValues(theObject.GetType())) {

     //make sure we have all the enumeration values in the collection
     if (this.ValuesCollection.Contains(item)) { }
     else {
        this.ValuesCollection.Add(item);
     }

     Console.WriteLine(item.ToString());
     Console.WriteLine(item.GetType().ToString());
 }
