NHibernate:查找属性是否映射到字段

是否有办法确定属性是否映射到字段。 我希望这可以生成类似“通用搜索”的内容：

如果我添加一个未映射到NHibernate的属性，搜索将抛出一个NHibernate.QueryException，其描述为“无法解析属性：Text1 of:C”

我正在映射如下属性：

class C
{    
    [Property(0, Column = "comment")]
    public virtual string Comment {get; set;}
}

使用NHibernate元数据API

ISessionFactory sessionFactory;

Type type = typeof(T);
IClassMetadata meta = sessionFactory.GetClassMetadata(type);

Disjunction disjunction = new Disjunction();
foreach (string mappedPropertyName in meta.PropertyNames)
{
    IType propertyType = meta.GetPropertyType(mappedPropertyName);

    if (propertyType == NHibernateUtil.String)
    {
        foreach (string word in words)
        {
            disjunction.Add(
                Expression.InsensitiveLike(
                    mappedPropertyName,
                    "%" + word + "%"));
        }
    }
}

ISessionFactory sessionFactory;

Type type = typeof(T);
IClassMetadata meta = sessionFactory.GetClassMetadata(type);

Disjunction disjunction = new Disjunction();
foreach (string mappedPropertyName in meta.PropertyNames)
{
    IType propertyType = meta.GetPropertyType(mappedPropertyName);

    if (propertyType == NHibernateUtil.String)
    {
        foreach (string word in words)
        {
            disjunction.Add(
                Expression.InsensitiveLike(
                    mappedPropertyName,
                    "%" + word + "%"));
        }
    }
}
