一、基本配置

　　<?xml version="1.0"?>
　　<configuration>
  　　<configSections>
    　　<section name="autofac" type="Autofac.Configuration.SectionHandler, Autofac.Configuration"/>
  　　</configSections>
  　　<autofac defaultAssembly="ConsoleApplication3">
    　　<components>
      　　<component type="ConsoleApplication3.Worker, ConsoleApplication3" service="ConsoleApplication3.IPerson" />
    　　</components>
  　　</autofac>
　　</configuration>

    static void Main(string[] args)
    {
        ContainerBuilder builder = new ContainerBuilder();
        builder.RegisterType<AutoFacManager>();
        builder.RegisterModule(new ConfigurationSettingsReader("autofac"));
        using (IContainer container = builder.Build())
        {
            AutoFacManager manager = container.Resolve<AutoFacManager>();
            manager.Say();
        } 
            
        Console.ReadKey();
    }

    builder.RegisterModule(new ConfigurationSettingsReader("autofac"));
    builder.Register(c => new AutoFacManager(c.Resolve<IPerson>()));
