Specify allowed enum values in a property

Question

Is it possible to specify that a enum property can only have a range of values?

enum Type
{
    None,
    One,
    Two,
    Three
}

class Object
{

Same as st4hoo's solution, only with reflection. You can make it as crazy as you would like.

using System;
using System.Linq;

namespace ConceptApplication
{
    static class Program
    {
        static void Main(string[] args)
        {
            var foobar = new Foobar
            {
                SomeProperty = Numbers.Five
            };
        }
    }

    public class Foobar
    {
        private static Numbers _someProperty;

        [NumberRestriction(Allowed = new[] {Numbers.One, Numbers.Two})]
        public Numbers SomeProperty
        {
            get { return _someProperty; }
            set
            {
                RestrictionValidator.Validate(this, "SomeProperty", value);

                _someProperty = value;
            }
        }
    }

    public class NumberRestriction : Attribute
    {
        public Numbers[] Allowed { get; set; }
    }

    public static class RestrictionValidator
    {
        public static void Validate(T sender, string propertyName, Numbers number)
        {
            var attrs = sender.GetType().GetProperty(propertyName).GetCustomAttributes(typeof(NumberRestriction), true);

            if (attrs.OfType().Any(attr => !(attr).Allowed.Contains(number)))
                throw new ArgumentOutOfRangeException();
        }
    }

    public enum Numbers
    {
        One,
        Two,
        Three,
        Four,
        Five
    }
}
