Autofac Beginner (1)

One 、 Create a console project

introduce nuget package

Two 、 Create an interface

using System;
using System.Collections.Generic;
using System.Text;

namespace _02_autofac
{
    
    internal interface Person
    {
    
        void Eat();
        void Say();
    }
}

3、 ... and 、 Create implementation classes

using System;
using System.Collections.Generic;
using System.Text;

namespace _02_autofac
{
    
    public class Student:Person
    {
    
        public void Eat()
        {
    
            Console.WriteLine(" have breakfast ");
        }
        public void Say()
        {
    
            Console.WriteLine(" Say good morning ");
        }
    }
}

Four 、 Create examples

using Autofac;
using System;
using System.ComponentModel;

namespace _02_autofac
{
    
    internal class Program
    {
    
        private static Autofac.IContainer Container {
     get; set; }
        static void Main(string[] args)
        {
    
            // Create a container 
            var builder = new ContainerBuilder();
            // establish builder, And in builder Registration type in .
            builder.RegisterType<Student>().As<Person>();
            // Instantiate container （ You can say the first step is to merge ）
            Container = builder.Build();
            // Where you need to use interfaces , adopt container To parse an instance of an excuse .
            Person person = Container.Resolve<Person>();
            person.Eat();
            person.Say();
        }
    }
}

5、 ... and 、 test result
