如何在C#中派生两个抽象类 [英] How to derive two abstract classes in C#

问题描述

我有应用结构-

public abstract class a 
{
}
//defined in a.dll
public abstract class b
{
}
//defined in b.dll

//Above 2 DLL reference added in main project where I want to derive both of this abstract classee like

public abstract class proj : a, b
{
}

我能够推导其中的任何一个，而不能同时推导两者.因此，请指导我有关我遗失的东西或我做的错误编码.

I am able to derive any one of it only not both. So pls guide me on missing things or wrong coding I had done.

推荐答案

您不能使用C#多重继承.但是，您可以使用接口.

You can't multiple inherit using C#. You can however achieve this by using an interface.

public interface Ia 
{

}

public interface Ib 
{

}

public abstract class MainProject : Ia, Ib  
{

}

C#接口仅允许方法，属性，事件和索引器的签名.您必须在proj(MainProgram)类中定义这些实现.

C# interfaces only allow signatures of methods, properties, events and indexers. You will have to define the implementation of these in the proj (MainProgram) class.
