AutoFac
AutoFac 在系统IOC中占有很大作用，越来越多的项目中使用到AutoFac,但是国内很难看到完整的AutoFac介绍，所以 我打算 通过翻译 AutoFac网站关于AutoFac的介绍、例子、相关扩展等来系统的介绍AutoFac,使更多的人更加了解并能够融会贯通的使用AutoFac。
使用“英文-中文”双语方式。

Autofac is an addictive Inversion of Control container for .NET 4.5, Silverlight 5, Windows Store apps, and Windows Phone 8 apps.
Autofac 是一个为.Net 4.5，Silverlight 5（银光），Windows Store apps（Widnows商店应用）和Windows Phone 8 apps（windows手机应用）的令人激动上瘾的IOC容器。
Register Components
Build up containers with lambdas, types, or pre-built instances of components. You can also scan assemblies for registrations.
注册组件（组成部分）
使用lambdas，类型，预建组件实例来构建容器。你依然能够通过扫描程序集来注册。
var builder = new ContainerBuilder();
// Register individual components//注册单独的组件
builder.RegisterInstance(new TaskRepository)
.As<ITaskRepository>();
builder.RegisterType<TaskController>();
builder.Register(c => new LogManager(DateTime.Now))
.As<ILogger>();
// Scan an assembly for components//为组件注册程序集
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.
表达式依赖
让Auto注入到你的构造器参数。它也能够黑醋栗属性和方法注入。
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.
灵活的模块化系统
努力实现Xml配置部署的好处与使用Autoface Modules代码的优势的平衡。
// 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.
简单的扩展点
Autofac 提供灵活的事件方便你知道组件是在什么时候被激活和被释放的，允许使用较少的代码实现大量的定制化。
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();
