•  Unity Application Block--通过配置文件读取映射

一、从应用程配置文件中读取映射

            IUnityContainer containerConfig = new UnityContainer();

            UnityConfigurationSection section =
                (UnityConfigurationSection)ConfigurationManager.GetSection("unity");

            section.Containers["containerTest"].Configure(containerConfig);

            ILog log = containerConfig.Resolve<ILog>();
            log.WriteLog("1.从应用程配置文件中读取映射");

            log.WriteLog("*****************************************************");

二、从外部配置文件中读取映射

            IUnityContainer containerExternal = new UnityContainer();

            FileConfigurationSource configExternal = new FileConfigurationSource("external.config");

            UnityConfigurationSection sectionExternal =
                (UnityConfigurationSection)configExternal.GetSection("unity");

            sectionExternal.Containers["containerExternal"].Configure(containerExternal);

            ILog logExternal = containerExternal.Resolve<ILog>();
            logExternal.WriteLog("2.从外部配置文件中读取映射");

 

三、App.config 内容

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Microsoft.Practices.Unity.Configuration" />
    <section name="enterpriseLibrary.ConfigurationSource" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ConfigurationSourceSection, Microsoft.Practices.EnterpriseLibrary.Common" />
  </configSections> 
  <unity>
    <containers>
      <container name="containerTest">
        <types>
          <type type="UnityTest.ILog,UnityTest" mapTo="UnityTest.MessageLog,UnityTest"/>
        </types>
      </container>
    </containers>
  </unity>
  <enterpriseLibrary.ConfigurationSource selectedSource="File Configuration Source">
    <sources>
      <add name="File Configuration Source" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.FileConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common"
        filePath="Config\control.config" />
    </sources>
  </enterpriseLibrary.ConfigurationSource>  
</configuration>

四、外部配置文件（external.config）内容 

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Microsoft.Practices.Unity.Configuration" />
  </configSections>
  <unity>
    <containers>
      <container name="containerExternal">
        <types>
          <type type="UnityTest.ILog,UnityTest" mapTo="UnityTest.MessageLog,UnityTest"/>
        </types>
      </container>
    </containers>
  </unity>
</configuration>
