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
  
  C#

  /// <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); } }
