//IOC容器,atofac演示
static void Main1(string[] args)
{
//最土的调用
//UserBll userbll = new UserBll();
//基于接口编程
//IUserBll userbll = new UserBll();
//userbll.AddNew("aaa", "123");
//Autofac
//先创建一个ContainerBuilder容器构建者
ContainerBuilder builder = new ContainerBuilder();
//演化1：注册IUserBll是IUserBll接口的实现类
//builder.RegisterType<UserBll>().As<IUserBll>();
//演化2：把UserBll注册为所有实现类，比如UserBll类实现了好几个接口，那么Resolve任何一个接口，都会返回我的对象
//builder.RegisterType<UserBll>().AsImplementedInterfaces();
//builder.RegisterType<DogBll>().AsImplementedInterfaces();
//演化3：首先拿到所有实现类所在程序集的名字
Assembly asm = Assembly.Load("MyBll");
//把MyBll程序集里的类都注册一遍
//builder.RegisterAssemblyTypes(asm).AsImplementedInterfaces();
//把MyBll程序集里的类都注册一遍,给属性自动输入实现类 ,SingleInstance()(单例)创建同一个对象
builder.RegisterAssemblyTypes(asm).AsImplementedInterfaces().PropertiesAutowired().SingleInstance();
IContainer container = builder.Build();
//Resolve获得实现类UserBll,创建IUserBll实现类的对象
//IUserBll bll = container.Resolve<IUserBll>();
//Console.WriteLine(bll.GetType());
//bll.AddNew("aa", "123");
//如果IUserBll有多个实现类，把实现类放到一个集合中
//IEnumerable<IUserBll> blls= container.Resolve<IEnumerable<IUserBll>>();
//foreach (IUserBll bll in blls)
//{
// Console.WriteLine(bll.GetType());
// bll.AddNew("aaa","333");
//}
//IDogBll dogbll=container.Resolve<IDogBll>();
//dogbll.bark();
ISchool school = container.Resolve <ISchool>();
school.FangXue();
ISchool school1 = container.Resolve <ISchool>();
//加了SingleInstance() 判断school和school1是不是同一个引用(对象)
Console.WriteLine(object.ReferenceEquals(school, school1));
Console.WriteLine("OK");
Console.ReadKey();
