Help with Enum...

Question

Can someone please give me a explenation of what this code below would do and explain how this works? I came across this example and do not even know where to start.
public T GetOne<T>(object o)
    {
        T one = (T)Enum.Parse(typeof(T), o.ToString());
        return one;
    }

Thanks,

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.
