之前嘗試很多次都失敗，這次終於成功註冊Controller、Service與Repository了，來記錄一下設定檔。

• AutofacConfig.cs

  /// <summary>
  /// DI設定檔
  /// </summary>
  public class AutofacConfig
  {
  	/// <summary>
  	/// 註冊DI注入物件資料
  	/// </summary>
  	public static void Register()
  	{
  		// 容器建立者
  		ContainerBuilder builder = new ContainerBuilder();
  
  		// 註冊Controllers
  		builder.RegisterControllers(Assembly.GetExecutingAssembly());
  
  		// 註冊Service
  		builder.RegisterAssemblyTypes(Assembly.GetExecutingAssembly())
  			   .Where(t => t.Name.EndsWith("Service"))
  			   .AsSelf();
  
  		// 註冊Repository
  		builder.RegisterAssemblyTypes(Assembly.GetExecutingAssembly())
  			   .Where(t => t.Name.EndsWith("Repository"))
  			   .AsSelf();
  
  		// 建立容器
  		IContainer container = builder.Build();
  
  		// 解析容器內的型別
  		AutofacDependencyResolver resolver = new AutofacDependencyResolver(container);
  
  		// 建立相依解析器
  		DependencyResolver.SetResolver(resolver);
  	}
  }

• Global.asax

  protected void Application_Start()
  {
      //加入這行
      AutofacConfig.Register();
  }
