.net core中使用autofac进行IOC

.net Core中自带DI是非常简单轻量化的，但是如果批量注册就得扩展，下面使用反射进行批量注册的

 public void AddAssembly(IServiceCollection services,string assemblyName)
         {
             if (!string.IsNullOrEmpty(assemblyName))
             {
                 var assembly = Assembly.Load(assemblyName);
                 var ts = assembly.GetTypes().Where(n => n.IsClass && !n.IsAbstract && !n.IsGenericType).ToList();
                 foreach (var item in ts.Where(s => !s.IsInterface))
                 {
                     var interfaceType = item.GetInterfaces();
                     if (interfaceType.Length == )
                         services.AddScoped(interfaceType[], item);
                     if (interfaceType.Length > )
                         services.AddScoped(interfaceType[], item);
                 }
             }
         }

下面是将自带的DI换成AutoFac进行批量DI

（NuGet引入Autofac，Autofac.Configuration，Autofac.Extensions.DependencyInjection）

 public class AutofacModule : Autofac.Module
     {
         //重写Autofac管道Load方法，在这里注册注入
         protected override void Load(ContainerBuilder builder)
         {
             //注册Service中的对象,Service中的类要以Service结尾，否则注册失败
              builder.RegisterAssemblyTypes(Assembly.Load("CoreDemo")).Where(a => a.Name.EndsWith("Service")).AsImplementedInterfaces();
         }
     }

 public IServiceProvider ConfigureServices(IServiceCollection services)
         {
             services.AddMvc();
             services.Configure<ConnectionOptions>(_configuration.GetSection("ConnectionStrings"));

             #region 注册Autofac
             //实例化Autofac容器
             var builder = new ContainerBuilder();
             //将Services中的服务填充到Autofac中
             builder.Populate(services);
             //新模块组件注册
             builder.RegisterModule<AutofacModule>();
             //创建容器
             var Container = builder.Build();
             //Autofac接管.net core内置DI容器
             return new AutofacServiceProvider(Container);
             #endregion
         }
