不实现继承的抽象成员 [英] Does not implement inherited abstract member

问题描述

嗨
我有一个抽象类

Hi I have a abstract class

public abstract class Service
    {
        public abstract void DoWork();

    }

和子课程

and sub classes are

public class Updater : Service
 {

 }

和

and

public class Sweeper : Service
{
    public string Path
    {
        get;
        set;
    }

    public int DaysToKeep
    {
        get;
        set;
    }
}

但是当我想构建项目时它会给我一个错误：

but when I want to build the project it give me an error :

'MyService.Sweeper' does not implement inherited abstract member 'MultiPurposeService.Service.DoWork() '

我尝试了什么：



解决了这个错误：

不实现继承的抽象成员

What I have tried:

solve this error :
does not implement inherited abstract member

推荐答案

有时候阅读错误的文档可能是个好主意...

Reading the error's documentation can be good idea sometimes...

MSDN [ ^ ]：

需要一个类来实现所有摘要基类中的成员，除非该类也是抽象的。

A class is required to implement all the abstract members in the base class, unless the class is also abstract.

如果你问自己为什么......抽象方法根据定义没有实现， howev呃，现在你创建了一个新类 - Sweeper - 它已经（继承）了一个方法 - DoWork。

当你打电话给Sweeper.DoWork时会发生什么？有些混乱，因为根本没有实现该方法。因此，链中的第一个非抽象类必须实现方法...

And if you ask yourself why... Abstract methods has no implementation by definition, however, now you created a new class - Sweeper - which has (inherited) a method - DoWork.
What should happen when you call Sweeper.DoWork? Some mess, as there is no implementation at all to that method. Therefore, the first non-abstract class in the chain must implement the method...
