AutoFac

AutoFac 在系統IOC中佔有很大做用，愈來愈多的項目中使用到AutoFac,可是國內很難看到完整的AutoFac介紹，因此 我打算 經過翻譯 AutoFac網站關於AutoFac的介紹、例子、相關擴展等來系統的介紹AutoFac,使更多的人更加了解並可以融會貫通的使用AutoFac。

使用「英文-中文」雙語方式。

Autofac is an addictive Inversion of Control container for .NET 4.5, Silverlight 5, Windows Store apps, and Windows Phone 8 apps.

Autofac 是一個爲.Net 4.5，Silverlight 5（銀光），Windows Store apps（Widnows商店應用）和Windows Phone 8 apps（windows手機應用）的使人激動上癮的IOC容器。

 

Register Components

Build up containers with lambdas, types, or pre-built instances of components. You can also scan assemblies for registrations.

註冊組件（組成部分）

使用lambdas，類型，預建組件實例來構建容器。你依然可以經過掃描程序集來註冊。

 

var builder = new ContainerBuilder();

// Register individual components//註冊單獨的組件

builder.RegisterInstance(new TaskRepository)

       .As<ITaskRepository>();

builder.RegisterType<TaskController>();

builder.Register(c => new LogManager(DateTime.Now))

       .As<ILogger>();

// Scan an assembly for components//爲組件註冊程序集

builder.RegisterAssemblyTypes(myAssembly)

       .Where(t => t.Name.EndsWith("Repository"))

       .AsImplementedInterfaces();

var container = builder.Build();

 

Express Dependencies

Let Autofac inject your constructor parameters for you. It can also handle property and method injection.

表達式依賴

讓Auto注入到你的構造器參數。它也可以黑醋栗屬性和方法注入。

 

public class TaskController

{

  private ITaskRepository _repository;

  private ILogger _logger;

  // Autofac will automatically find the registered

  // values and pass them in for you.

  public TaskController(

    ITaskRepository repository,

    ILogger logger)

  {

    this._repository = repository;

    this._logger = logger;

  }

}

 

Flexible Module System

Strike a balance between the deployment-time benefits of XML configuration and the power of code with Autofac modules.

靈活的模塊化系統

努力實現Xml配置部署的好處與使用Autoface Modules代碼的優點的平衡。

 

// Specify complex registrations in code

public class CarTransportModule : Module

{

  public bool ObeySpeedLimit { get; set; }

  protected override void Load(ContainerBuilder builder)

  {

    builder.RegisterType<Car>().As<IVehicle>();

    if (ObeySpeedLimit)

      builder.RegisterType<SaneDriver>().As<IDriver>();

    else

      builder.RegisterType<CrazyDriver>().As<IDriver>();

  }

}

 

<!-- Change deployment-time behavior with XML -->

<autofac>

  <module type="CarTransportModule">

    <properties>

      <property name="ObeySpeedLimit" value="true" />

    </properties>

  </module>

</autofac>

 

Simple Extension Points

Autofac provides activation events to let you know when components are being activated or released, allowing for a lot of customization with little code.

簡單的擴展點

Autofac 提供靈活的事件方便你知道組件是在何時被激活和被釋放的，容許使用較少的代碼實現大量的定製化。

 

var builder = new ContainerBuilder();

// Once a listener has been fully constructed and is

// ready to be used, automatically start listening.

builder.RegisterType<Listener>()

       .As<IListener>()

       .OnActivated(e => e.Instance.StartListening());

// When a processor is being constructed but before

// it's ready to be used, call an initialization method.

builder.RegisterType<Processor>()

       .OnActivating(e => e.Instance.Initialize());

var container = builder.Build();
