We have a enums how we get enums and its values in a list ?

have a look on this for Enum reference

enum EnumRank
       {
           First=1,
           Second=2,
           Third=3

       }
       static void Main(string[] args)
       {
           //To Get the list of enum Values
           List<int> Numbers = Enum.GetValues(typeof(EnumRank)).Cast<int>().ToList();  // 1,2 3

           //To Get the List of Enum Names
           List<string> Names = Enum.GetNames(typeof(EnumRank)).ToList();  //First, Second, Third

           // Cast Enum to a string
           EnumRank value = EnumRank.First;
           string name = Enum.GetName(typeof(EnumRank), value); // First

           // Cast a string value to Enum Object
           string enumInString = "Third";
           EnumRank enumValue = (EnumRank)Enum.Parse(typeof(EnumRank), enumInString); // Third Enum

       }

Solutions 1 and 2 are incomplete. The trouble starts when some enumeration members have the same integer value (which is often needed). Anyway, these approached don't give you enumeration type members as you define them.
