Mini 容器学习笔记6——组件的获取(应用)

1. 通过组件Id获取组件实例：

       [Test]public void GetByIdTest(){ServiceRegistry.Register<Person>("person");var person = ServiceLocator.Get<IPerson>("person");Assert.IsTrue(person != null);var person2 = ServiceLocator.Get<Person>("person");Assert.IsTrue(person2 != null);Assert.AreSame(person, person2);Assert.IsTrue(Person.HasVisited);}

2. 通过契约类型获取组件实例：

       [Test]public void GetByTypeTest(){ServiceRegistry.Register<Person>();var person = ServiceLocator.Get<IPerson>();Assert.IsTrue(person != null);var person2 = ServiceLocator.Get<IPerson,Person>();Assert.IsTrue(person2 != null);Assert.AreSame(person, person2);Assert.IsTrue(Person.HasVisited);}

3. 通过契约类型获取所有组件实例：

   [Contract]interface IPerson{string Name { get; set; }}class Person : IPerson{public string Name { get; set; }public static bool HasVisited;public Person(){HasVisited = true;}}[Contract]interface IHorse{}[Component]class RedHorse : IHorse{}class BlackHorse : IHorse{}class Person2 : IPerson{public string Name { get; set; }public IHorse Horse { get; set; }public Person2(IHorse horse){Horse = horse;}public Person2() { }}[Test]public void GetAllTest(){ServiceRegistry.Register<Person>().Register(typeof(Person2));var person = ServiceLocator.Get<IPerson>();Assert.IsTrue(person != null);Assert.IsTrue(typeof(IPerson).IsAssignableFrom(person.GetType()));var items = ServiceLocator.GetAll<IPerson>().ToArray();Assert.IsTrue(items.Length == 2);Assert.IsTrue(items[0] is Person);Assert.IsTrue(items[1] is Person2);}

4. 通过向组件的构造函数传递参数数组的方式获取：

    [Contract]interface IParameterConstructorInterface{int Id { get; }string Name { get; }IPerson Person { get; }}class ParameterConstructorClass : IParameterConstructorInterface{public int Id { get; private set; }public string Name { get; private set; }public IPerson Person { get; private set; }public ParameterConstructorClass(int id, string name, IPerson person){Id = id;Name = name;Person = person;}}

       //传递数组的方式

       [Test]public void NeedParameterConstructorTest(){var person = new Person();ServiceRegistry.Register<ParameterConstructorClass>();var instance = ServiceLocator.Current.Get(typeof(IParameterConstructorInterface), 10, "ZhangSan", person) as IParameterConstructorInterface;Assert.IsNotNull(instance);Assert.IsNotNull(instance);Assert.AreEqual(10, instance.Id);Assert.IsTrue("ZhangSan"== instance.Name);Assert.AreSame(person, instance.Person);}

        //传递命名参数字典[Test]public void NeedNamedParameterConstructorTest(){var ps = new Dictionary<string, object>();var person = new Person();ps["id"] = 10;ps["name"] = "ZhangSan";ps["person"] = person;ServiceRegistry.Register<ParameterConstructorClass>();var instance = ServiceLocator.Current.Get(typeof(IParameterConstructorInterface), ps) as IParameterConstructorInterface;Assert.IsNotNull(instance);Assert.AreEqual(10, instance.Id);Assert.IsTrue("ZhangSan" == instance.Name);Assert.AreSame(person, instance.Person);}
