C# 遍历枚举（枚举是目的，遍历（获取）是手段）

  public enum Suits
    {
        Spades,
        Hearts,
        Clubs,
        Diamonds,
        NumSuits
    }

 private static void Main(string[] args)
        {
            foreach (Suits suit in Enum.GetValues(typeof(Suits)))
            {
                Console.WriteLine((int)suit+ ":" + suit);
            }
        }
