配置文件接口。通过在配置文件中配置工厂，在Unity中实现Client类构造函数自动注入。

配置文件：
<configSections>
<section name="unity"
type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection,Microsoft.Practices.Unity.Configuration" />
</configSections>
<unity>
<typeAliases>
<!-- Lifetime manager types -->
<typeAlias alias="singleton"
type="Microsoft.Practices.Unity.ContainerControlledLifetimeManager,
Microsoft.Practices.Unity" />
</typeAliases>
<containers>
<container>
<types>
<!-- Lifetime managers specified using the type aliases -->
<type type= "LibraryTest.Test.IFactory, LibraryTest"
mapTo="LibraryTest.Test.SGIPFactory, LibraryTest">
<lifetime type="singleton" />
</type>
<type type= "LibraryTest.Test.IFactory, LibraryTest" name="CMPP"
mapTo="LibraryTest.Test.CMPPFactory, LibraryTest">
<lifetime type="singleton" />
</type>
</types>
</container>
</containers>
</unity>
</configuration>
调用代码:
private static void AnotherWays2()
{
IUnityContainer container = new UnityContainer();
UnityConfigurationSection section =
(UnityConfigurationSection)ConfigurationManager.GetSection("unity");
section.Containers.Default.Configure(container);
SmsPlatform smf = container.Resolve<SmsPlatform>();
smf.Run();
Console.ReadLine();
}
