Answer 1

The easy and clear way for casting an int to enum in C#:

public class Program
{
    public enum Color : int
    {
        Blue   = 0,
        Black  = 1,
        Green  = 2,
        Gray   = 3,
        Yellow = 4
    }

    public static void Main(string[] args)
    {
        // From string
        Console.WriteLine((Color) Enum.Parse(typeof(Color), "Green"));

        // From int
        Console.WriteLine((Color)2);

        // From number you can also
        Console.WriteLine((Color)Enum.ToObject(typeof(Color), 2));
    }
}
