假设我有一类SomeClass的，有一个查找字典： DataDictionary;

Assume I have a class "SomeClass" that has a lookup dictionary: DataDictionary;

我目前在SomeClass.hbm.xml一个这样的映射：

I currently have a mapping in SomeClass.hbm.xml like this:

<class name="SomeClass>

  <id name="ID" type="System.Guid">
    <generator class="guid" />
  </id>

  <map name="DictionaryProperty" table="SomeClass_Data">
    <key column="SomeClassID" />
    <index column="Key" type="System.String" />
    <element column="Value" type="System.String" />
  </map>

</class>

我想使用NHibernate的新（版本3.2）在code映射。我将如何映射上面的字典属性？

I want to use NHibernate's new (version 3.2) By Code mappings. How would I map the dictionary property above?

目前我有：

  public class SomeClassMap :ClassMap<SomeClass>
  {

     public SomeClassMap()
     {
        Id(x => x.ID, mapping => mapping.Generator(Generators.Guid));
        Map(x = x.DictionaryProperty, mapping =>
           {
              mapping.Key(k => k.Column("SomeClassID"));
              mapping.Table("SomeClassData");
           });
     }

  }

晴我在对于如何指定索引的等效和为一个字典映射的元素的损失。

Mostly I am at a loss for how to specify the equivalent of the index and the element for a dictionary mapping.

推荐答案

字典映射的每个部分都需要一个单独的委托：

Each part of the dictionary mapping requires a separate delegate:

Map(x => x.DictionaryProperty,
    mapping =>
    {
        mapping.Key(k => k.Column("SomeClassID"));
        mapping.Table("SomeClassData");
    },
    mapping => mapping.Element(k => k.Column("Key")),
    mapping => mapping.Element(k => k.Column("Value")));

第一个元素是地图键（首页是过时的地图），而第二个是元素。

The first Element is the map-key (index is obsolete for map), and the second one is the element.
