public static string GetDescription<T>(this T source)
{
    FieldInfo fi = source.GetType().GetField(source.ToString());

    DescriptionAttribute[] attributes = (DescriptionAttribute[])fi.GetCustomAttributes(
        typeof(DescriptionAttribute), false);

    if (attributes != null && attributes.Length > 0) 
        return attributes[0].Description;
    else

// In Enums.NET you'd use:

string description = ((MyEnum)value).AsString(EnumFormat.Description);
