Question

如果物体继承从一个接口继承的抽象类别,则该物体将继承接口。

这种接口能否与依赖性注射集装箱使用?

感谢。

Answer 1

是的,它确实能够实施这一接口,因为这样做是真实的,可以作为一种依赖性注入。

这是一种快速测试,证明接口的实施:

using System;

interface IParent {}
abstract class Parent : IParent {}

class Example : Parent
{
    static void Main()
    {
        Console.WriteLine(new Example() is IParent);
    }
}

Answer 2

I consider interface as a kind of contract. Since the abstract class inherite from the interface, it is surely demanded to implement the functions of the interface. And the object (in fact the class of it) is demanded to override the abstract function of the abstract class. In my opinion, this pattern is only suitable for stable interface or abstract class. Cause once there was change to the contract of the interface or abstract class, that would be a disaster. Oops~~, you screw the build!

我更喜欢将虚拟班级用于基类,使功能变得虚拟,这样,你就可以在子类中凌驾于与接口/组合式解决方案相同的等级,并且能够方便地增加新的超负荷。
