WebAPi依賴注入  使用記錄 筆記

1.NuGet包安裝

2.控制器加入構造函數

 

3.Global.asax  ----Application_Start 

應用程序啟動時

using Autofac.Integration.WebApi;

 /*依賴注入*/
            var builder = new ContainerBuilder();
            builder.RegisterApiControllers(Assembly.GetExecutingAssembly());
            builder.RegisterType<DbService>();
            var container = builder.Build();
            var resolver = new AutofacWebApiDependencyResolver(container);
            GlobalConfiguration.Configuration.DependencyResolver = resolver;
