Spring.net inject Dictionary.

http://stackoverflow.com/questions/4591638/spring-net-ref-to-dictionary-item

<object name="Paths" id="Paths" type="System.Collections.Generic.Dictionary&lt;string,string&gt;">
    <constructor-arg>
      <dictionary key-type="string" value-type="string">
        <entry key="cfgFile">
          <value>config.txt</value>
        </entry>
      </dictionary>
    </constructor-arg>
  </object> 

You can use the @(object-id-here) expression syntax to retrieve an object from the Spring context using an expression.

<object name="obj1" type="MyTestClass" depends-on="Paths">
  <property name="cfg" expression="@(Paths)['cfgFile']"/>
</object>

Edit - below is the answer that was accepted

I can imagine that you would like this kind of configuration to be available in your app.config. If so, you can use the PropertyPlaceholderConfigurer; see the example in section 5.9.2.1.

In your case, it would look something like this:

<!-- app.config -->
<configuration>

  <configSections>
    <sectionGroup name="spring">
      <section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
    </sectionGroup>
    <section name="PathConfiguration" type="System.Configuration.NameValueSectionHandler"/>
  </configSections>

  <PathConfiguration>
    <add key="cfgFile" value="config.txt"/>
    <add key="otherCfgFile" value="otherconfig.txt"/>
  </PathConfiguration>

  <spring>
    <context>
      <resource uri="mycongfig.xml"/>
    </context>
  </spring>

</configuration>

And your myconfig.xml contains:

<!-- ... -->
<object name="obj1" type="MyTestClass">
    <property name="cfg" value="${cfgFile}"/>
</object>

<object name="appConfigPropertyHolder" 
        type="Spring.Objects.Factory.Config.PropertyPlaceholderConfigurer, Spring.Core">

    <property name="configSections">          
      <value>PathConfiguration</value>                              
    </property>              

</object>
<!-- ... -->

Note that instead of app.config, you can use any other IResource.

An alternative solution is to define the cfgFile as an object in your configuration and then in your dictionary reference this object using value-ref (see spring docs 5.3.2.4 on how to do this). But this (probably) isn't what you are looking for, since you're injecting primitive values (so it's not worth the effort of creating an explicit ConfigurationObject).

The elements of an OrderedDictionary are not sorted by the key, unlike the elements of a SortedDictionary<TKey, TValue> class. You can access elements either by the key or by the index
