在C＃中，我可以知道什么样的孩子从我继承了基类？ [英] In C#, can I know in the base class what children inherited from me?

问题描述

我有一个基类的车辆和一些儿童类，如汽车，摩托车等。从车辆的继承。 在每一个儿童类有一个函数围棋（）; 现在我想登录的每一个车辆信息时，函数围棋（）触发，并在登录我想知道哪种车辆做到了。

I have a base class vehicle and some children classes like car, motorbike etc.. inheriting from vehicle. In each children class there is a function Go(); now I want to log information on every vehicle when the function Go() fires, and on that log I want to know which kind of vehicle did it.

例如：

public class vehicle 
{
      public void Go()
      {
           Log("vehicle X fired");
      }
}
public class car : vehicle
{
       public void Go() : base()
       {
           // do something
       }
}

我怎么能知道在功能日志汽车基地时打电话给我（）？ 谢谢你，

How can I know in the function Log that car called me during the base()? Thanks,

推荐答案

调用 的GetType（） 从Vehicle.Go（）会的工作 - 但前提是围棋（）实际上是一个名为

Calling GetType() from Vehicle.Go() would work - but only if Go() was actually called.

执行的一种方法是使用模板方法模式：

One way of enforcing this is to use the template method pattern:

public abstract class Vehicle 
{
    public void Go()
    {
        Log("vehicle {0} fired", GetType().Name);
        GoImpl();
    }

    protected abstract void GoImpl();
}

public class Car : Vehicle
{
    protected override void GoImpl()
    {
        // do something
    }
}
