Unity:建立一本字典

Question

我正在将Castle/Monorails应用程序转换为Unity/Asp.NET MVC,我不得不尝试转换此组件配置:

<component
  id="ComponentBaseConfiguration"
  service="MyFakeNamespace.BOL.IConfiguration, MyFakeAppDll"
  type="MyFakeNamespace.BOL.ConfigurableConfiguration, MyFakeAppDll">
  <parameters>
    <!-- Setting Configuration (Dictionary<string,string>)-->
    <Config>
      <dictionary>
        <entry key="localHost">#{LocalHost}</entry>            
        <entry key="contentHost">#{ContentHost}</entry>
        <entry key="virtualDir">#{VirtualDir}</entry>            
      </dictionary>
    </Config>
  </parameters>

似乎Unity支持Array但不支持Dictionary,我想做这样的事情:

<unity>
<containers>
    <container>
        <types>
            <type name="ComponentBaseConfiguration" type="MyFakeNamespace.BOL.IConfiguration, MyFakeAppDll" mapTo="MyFakeNamespace.BOL.ConfigurableConfiguration, MyFakeAppDll">
                <typeConfig extensionType="Microsoft.Practices.Unity.Configuration.TypeInjectionElement, Microsoft.Practices.Unity.Configuration">
                    <property name="Config" propertyType="System.Collections.Generic.Dictionary`2[[System.String, mscorlib], [System.String, mscorlib]],mscorlib">
                        <dictionary>
                            <entry key="localHost">127.0.0.1</keyedValue>
                            <entry key="contentHost">\\content</keyedValue>
                            <entry key="virtualDir">/</keyedValue>
                        </dictionary>
                    </property>
                </typeConfig>
            </type>
        </types>
    </container>
</containers></unity>

我怎样才能实现这样的目标？

我认为你必须使用方法 -element来存档它.这不是一件好事,而是一种解决方法

您的类型必须定义一个方法Add(字符串键,字符串值),unity容器用它来注入值.

<method name="Add">
 <param name="key" parameterType="string">
  <value value="localHost"/>
 </param>
 <param name="value" parameterType="string">
  <value value="127.0.0.1"/>
 </param>
</method>

Unity肯定不支持容器配置的字典.请参阅使用Unity容器构建字典？
