ASP.NET AutoFac注入步骤

Autofac注入的步骤：
1.在项目UI层新建一个文件夹Dependcy创建一个AutofacConfig类添加一个RegisterAutofac方法

 public static void RegisterAutofac() {
            // 创建一个容器
            var builder = new ContainerBuilder();
            Type basetype = typeof(IDenpendecy);
            var assemblys = AppDomain.CurrentDomain.GetAssemblies().ToList();
            builder.RegisterAssemblyTypes(assemblys.ToArray())
                .Where(t => basetype.IsAssignableFrom(t) && t != basetype)
                .AsImplementedInterfaces().InstancePerLifetimeScope();

            Type repository = typeof(IDenpendecyRepository);
            builder.RegisterAssemblyTypes(assemblys.ToArray())
                .Where(t => repository.IsAssignableFrom(t) && t != repository)
                .AsImplementedInterfaces().InstancePerLifetimeScope();
            builder.RegisterControllers(assemblys.ToArray());
            var container = builder.Build();
            DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
  }

2.在Global.asax中调用方法
 //注册Autofac
 AutofacConfig.RegisterAutofac();

3.数据访问层创建IRepositor接口文件夹和Repository类文件夹
public interface IAdminInfoRepository:IDenpendecyRepository
{
}

public class AdminInfoRepository:IAdminInfoRepository
{
}

4.业务层创建IService接口文件夹和Service类文件夹
 public  interface IAdminInfoService: IDenpendecy
 {
}

public class AdminInfoService:IAdminInfoService
 {
        private IAdminInfoRepository adminInfoRepository;
        public AdminInfoService(IAdminInfoRepository iadminInfoRepository)
        {
            adminInfoRepository = iadminInfoRepository;
        }
}

5.在控制器AdminController中
public class AdminController : Controller
 {
        private IAdminInfoService adminInfoService;
        public AdminController(IAdminInfoService iadminInfoService)
        {
            adminInfoService = iadminInfoService;
        }
}
