.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 == 1)
                        services.AddScoped(interfaceType[0], item);
                    if (interfaceType.Length > 1)
                        services.AddScoped(interfaceType[1], 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
        }
