NHibernate中enum的映射集合

我有一个包含枚举集合的类:

类别1.cs

public enum Language
{
    Serbian = 1,
    Croatian,
    Ukrainian,
}

public class Class1
{
   private IList<Language> m_languages = new List<Language>();
   public virtual IList<Language> Languages
   {
          get { return m_languages; }
          set { m_languages = value; }
   }
}
