Getting attributes of Enum's value

This should do what you need.

var enumType = typeof(FunkyAttributesEnum);
var memberInfos = enumType.GetMember(FunkyAttributesEnum.NameWithoutSpaces1.ToString());
var enumValueMemberInfo = memberInfos.FirstOrDefault(m => m.DeclaringType == enumType);
var valueAttributes = 
      enumValueMemberInfo.GetCustomAttributes(typeof(DescriptionAttribute), false);
var description = ((DescriptionAttribute)valueAttributes[0]).Description;

This piece of code should give you a nice little extension method on any enum that lets you retrieve a generic attribute. I believe it's different to the lambda function above because it's simpler to use and slightly - you only need to pass in the generic type.

public static class EnumHelper
{
    /// <summary>
    /// Gets an attribute on an enum field value
    /// </summary>
    /// <typeparam name="T">The type of the attribute you want to retrieve</typeparam>
    /// <param name="enumVal">The enum value</param>
    /// <returns>The attribute of type T that exists on the enum value</returns>
    /// <example><![CDATA[string desc = myEnumVariable.GetAttributeOfType<DescriptionAttribute>().Description;]]></example>
    public static T GetAttributeOfType<T>(this Enum enumVal) where T:System.Attribute
    {
        var type = enumVal.GetType();
        var memInfo = type.GetMember(enumVal.ToString());
        var attributes = memInfo[0].GetCustomAttributes(typeof(T), false);
        return (attributes.Length > 0) ? (T)attributes[0] : null;
    }
}

This is a generic implementation using a lambda for the selection

public static Expected GetAttributeValue<T, Expected>(this Enum enumeration, Func<T, Expected> expression)
    where T : Attribute
{
    T attribute =
      enumeration
        .GetType()
        .GetMember(enumeration.ToString())
        .Where(member => member.MemberType == MemberTypes.Field)
        .FirstOrDefault()
        .GetCustomAttributes(typeof(T), false)
        .Cast<T>()
        .SingleOrDefault();

    if (attribute == null)
        return default(Expected);

    return expression(attribute);
}

Call it like this:

string description = targetLevel.GetAttributeValue<DescriptionAttribute, string>(x => x.Description);
