Help with Enum...

Consider that you have enumeration of numbers:
  enum Numbers
        {
            One, Two, Three
        }
        static void Main(string[] args)
        {           
            Numbers n = (Numbers)Enum.Parse(typeof(Numbers), "Three"));                    
        } 

Enum.Parse function will return an enumerated object if your string will match name of one from Numbers.
Then you explicitly cast it to your Numbers enum.

public T GetOne(object o)
    {
        T one = (T)Enum.Parse(typeof(T), o.ToString());
        return one;
    }
This is a generic function which does the same but with some enumeration T.
The previous example could be done with your function like that:
 enum Numbers
        {
            One, Two, Three
        }
        static void Main(string[] args)
        {
            Numbers n = GetOne("Three");
            Console.WriteLine(n.ToString());    
        }
        public static T GetOne(object o)
        {
            T one = (T)Enum.Parse(typeof(T), o.ToString());
            return one;
        }      
String "Three" is passed as param but you can pass any object.
