Unity创建实例：普通实例，单例，线程单例

//Unity容器，默认情况下生成普通对象
//在注册时传入参数new ContainerControlledLifetimeManager()，可以创建单例对象
//在注册的时候传入参数new PerThreadLifetimeManager(),可以创建线程单例对象
//容器不知可以生成对象，还可以管理对象的生命周期
IUnityContainer ucontainer = new UnityContainer();//ContainerControlledLifetimeManager
ucontainer.RegisterType<IPhone, ApplePhone>(new ContainerControlledLifetimeManager());
//单例是只要通过容器生成的对象都是同一个实例，在系统中不同地方获取的单利都是同一个实例
IPhone phone1 = ucontainer.Resolve<IPhone>();
IPhone phone2 = ucontainer.Resolve<IPhone>();
Console.WriteLine($"{object.ReferenceEquals(phone1, phone2)}");

//线程单例：同一个线程就是同一个实例，不同线程就是不同的实例
IPhone phone1 = null;
IPhone phone2 = null;
IPhone phone3 = null;
IPhone phone4 = null;
IPhone phone5 = null;
IUnityContainer ucontainer = new UnityContainer();
ucontainer.RegisterType<IPhone, AndroidPhone>(new PerThreadLifetimeManager());
phone1 = ucontainer.Resolve<IPhone>();
phone2 = ucontainer.Resolve<IPhone>();
Console.WriteLine($"12的当前线程ID:{Thread.CurrentThread.ManagedThreadId}");

new Action(() =>
{
phone3 = ucontainer.Resolve<IPhone>();
Console.WriteLine($"3的当前线程ID:{Thread.CurrentThread.ManagedThreadId}");
}).BeginInvoke(null, null);

new Action(() =>
{
phone4 = ucontainer.Resolve<IPhone>();
Console.WriteLine($"4的当前线程ID:{Thread.CurrentThread.ManagedThreadId}");
}).BeginInvoke(arg =>
{
phone5 = ucontainer.Resolve<IPhone>();
Console.WriteLine($"5的当前线程ID:{Thread.CurrentThread.ManagedThreadId}");
}, null);
Thread.Sleep(5000);
Console.WriteLine($"12:{object.ReferenceEquals(phone1, phone2)}");
Console.WriteLine($"13:{object.ReferenceEquals(phone1, phone3)}");
Console.WriteLine($"14:{object.ReferenceEquals(phone1, phone4)}");
