我有一个属性域类的IList＆LT;字符串＆GT; ，我想要映射到一个表，一个单一的数据值（即它有一个ID，一个外国密钥ID域实体表，并varchar数据列）。

I have a domain class with a property IList<string> that I want to map to a table with a single data value (i.e. it has an ID, a foreign key ID to the domain entity table, and a varchar data column).

我不断收到错误：协会引用未映射类：System.String 。

我如何能表映射到字符串的集合？

How can I map a table to a collection of strings?

推荐答案

我只是碰到了类似的情况;而且我发现它确实有可能映射字符串的集合。 请注意，您必须对这些字符串作为映射值对象。

I just ran into a similar situation; and I found that it is indeed possible to map a collection of strings. Note that you'll have to map those strings as value objects.

这是我有：

public class Chapter
{
    private ISet<string> _synonyms = new HashedSet<string>();

    public ReadOnlyCollection<string> Synonyms
    {
       get { return new List<string>(_synonyms).AsReadOnly(); }
    }
}

映射：

<class name="Chapter" table="Chapter">
   <set name="Synonyms" table="ChapterSynonyms">
       <key column="ChapterId" />
       <element column="ChapterCode" type="string" />
   </set>
</class>
