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();
        }
    }
}
