Tip: C# dynamic 'Enum' like solution.

Hi,
This is very usefull if you wish to be able to create dynamic enums.

Motivation
* You need to enumerate something but wish to add items to it in runtime (e.g. your server should support v1 protocol and v2 protocol where v2 protocol extends v1.enum).

* You wish to extand this enum dynamically by an outside addin.

Solution and prof

Code Snippet

12. enum MyEnum : ulong
13. {
14.     // NOTICE: string_name = ulong_value,
15.     first = 2<<0,
16.     second = 2<<1,
17.     last = 2<<2,
18.  
19.     max = 2 << 63
20.     // dynamic string name = dynamic ulong value!
21. }
22.  
23. Dictionary<string, ulong> DynamicEnum1 = new Dictionary<string, ulong>()
24. {
25.     {"first", 2 << 0},
26.     {"second", 2 << 1},
27.     {"last", 2 << 2},
28.  
29.     {"max", 2 << 63}
30. };
31.  
32. public void usage()
33. {
34.     MyEnum qwe = MyEnum.first;
35.  
36.     DynamicEnum1.Add("another_one", 2 << 3);
37.     UInt64 qwe2 = DynamicEnum1["first"];
38.  
39.     // (UInt64)qwe == qwe2!!
40. }

Hope it helps.
