一．概述

EnterpriseLibrary Configuration Facility就好像是在容器和数据类之间的桥，让我们可以轻松得去读取和操作配置文件。熟悉Enterprise Library的人都知道，在Enterprise Library中有一个Configuration Application Block，它可以使我们方便的从各种存储中读写配置信息，通过EnterpriseLibrary Configuration Facility我们就可以像使用普通的组件那样去注册一个数据类，它会用configurationkey来映射到Enterprise Library的配置文件中。先来看一下该Facility的相关信息：

Facility Information
Uses Proxy	No
Requires Configuration	Yes
Uses Attributes	No
Version	Beta 2

二．使用Facility

1．配置文件，这里使用配置文件注册组件的方式，放在应用程序配置文件中，这里唯一需要注意的是configurationkey，这个特性不能写错：

<？xml version="1.0" encoding="utf-8" ？>
<configuration>
  <configSections>
    <section name="enterpriselibrary.configurationSettings" type="System.Configuration.IgnoreSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
    <section name="castle" type="Castle.Windsor.Configuration.AppDomain.CastleSectionHandler, Castle.Windsor" />
  </configSections>
  <enterpriselibrary.configurationSettings xmlns:xsd="" xmlns:xsi=""
    defaultSection="" applicationName="Application" xmlns="">
    <configurationSections>
      <configurationSection name="EditorSettings" encrypt="false">
        <storageProvider xsi:type="XmlFileStorageProviderData" name="XML File Storage Provider" path="../../EditorSettings.config" />
        <dataTransformer xsi:type="XmlSerializerTransformerData" name="Xml Serializer Transformer">
          <includeTypes />
        </dataTransformer>
      </configurationSection>
    </configurationSections>
    <keyAlgorithmStorageProvider xsi:nil="true" />
  </enterpriselibrary.configurationSettings>
  <castle>
    <facilities>
      <facility id="configuration" type="Castle.Facilities.EnterpriseLibrary.Configuration.EnterpriseConfigurationFacility, Castle.Facilities.EnterpriseLibrary.Configuration" />
    </facilities>
    <components>
      <component id="editorfontdata" type="ConfigurationQuickStart.EditorFontData, Castle.Facilities.EnterpriseLibrary.Configuration.Tests"
        configurationkey="EditorSettings" />
      <component id="editorservice" type="Castle.Facilities.EnterpriseLibrary.Configuration.Tests.EditorService, Castle.Facilities.EnterpriseLibrary.Configuration.Tests" />
    </components>
  </castle>
</configuration>
