ASP.NET Core中使用Autofac

⒈添加相关依赖

Install-Package Autofac

⒉扫描项目接口实现类　

 using Autofac;
 using System;
 using System.Collections.Generic;
 using System.Reflection;
 using System.Text;

 namespace Unity_Test.Autofac
 {
     public class AutofacConfig
     {
         private static Lazy<IContainer> container = new Lazy<IContainer>(() =>
         {
             var containerBuilder = new ContainerBuilder();
             RegisterTypes(containerBuilder);
             var container = containerBuilder.Build();
             return container;
         });

         public static IContainer GetConfiguredContainer()
         {
             return container.Value;
         }

         private static void RegisterTypes(ContainerBuilder containerBuilder)
         {

             var dataAccess = Assembly.GetExecutingAssembly();

             containerBuilder.RegisterAssemblyTypes(dataAccess)
                 .Where(w => w.Namespace.Contains("Unity_Test"))
                 .AsImplementedInterfaces();
         }
     }
 }

⒊代码中注入

 using Autofac;
 using Autofac.Core;
 using System;
 using Unity_Test.Autofac;

 namespace Unity_Test
 {
     class Program
     {
         static void Main(string[] args)
         {
             IService service = AutofacConfig.GetConfiguredContainer().Resolve<IService>();
             service.sayHello();
             Console.ReadKey();
         }
     }
 }
