Enum extensions

Sharing these Enum extension methods I wrote yesterday.

using System;
using System.ComponentModel;

namespace Nitin.Spike.EnumExtensions
{
    class Program
    {
        static void Main()
        {
            const Colors someColor = Colors.Red;
            string description = someColor.Description();
            if (someColor.HasDescription())
            {
                if (someColor.HasDescription("indicates stop", StringComparison.OrdinalIgnoreCase))
                {
                    Console.WriteLine("Works");
                }
            }
        }
    }
    public enum Colors
    {
        [Description("Indicates Stop")]
        Red,
        [Description("Indicates Nothing")]
        Blue,
        [Description("Indicates Go")]
        Green
    }
    public static class EnumExtensions
    {
        public static string Description(this Enum someEnum)
        {
            var memInfo = someEnum.GetType().GetMember(someEnum.ToString());

            if (memInfo != null && memInfo.Length > 0)
            {
                object[] attrs = memInfo[0].GetCustomAttributes(typeof(DescriptionAttribute),false);

                if (attrs != null && attrs.Length > 0)
                    return ((DescriptionAttribute)attrs[0]).Description;
            }
            return someEnum.ToString();
        }
        public static bool HasDescription(this Enum someEnum)
        {
            return !string.IsNullOrWhiteSpace(someEnum.Description());
        }
        public static bool HasDescription(this Enum someEnum, string expectedDescription)
        {
            return someEnum.Description().Equals(expectedDescription);
        }
        public static bool HasDescription(this Enum someEnum, string expectedDescription, StringComparison comparisionType)
        {
            return someEnum.Description().Equals(expectedDescription, comparisionType);
        }
    }
}
