从C#中的两个类继承 [英] inherit from two classes in C#

问题描述

可能重复:
C#中的多重继承

我有两个类A和B.这两个类不能互相继承.我正在创建一个名为Class C的新类.现在，我想通过继承来实现A类和B类中的方法.我知道在C#中无法进行多重继承，但是还有其他方法可以做到这一点吗?

I have two classes Class A and Class B. These two classes cannot inherit each other. I am creating new class called Class C. Now, I want to implement the methods in class A and class B by inheriting. I am aware that multiple inheritance is not possible in C# but is there any other way to do this?

推荐答案

在C#中无法进行多重继承，但是可以使用接口模拟多重继承，请参见

Multitiple inheritance is not possible in C#, however it can be simulated using interfaces, see Simulated Multiple Inheritance Pattern for C#.

基本思想是为要访问的类 B 上的成员(称为 IB )定义一个接口，然后使 C 从 A 继承并通过内部存储 B 的实例来实现 IB ，例如:

The basic idea is to define an interface for the members on class B that you wish to access (call it IB), and then have C inherit from A and implement IB by internally storing an instance of B, for example:

class C : A, IB
{
    private B _b = new B();

    // IB members
    public void SomeMethod()
    {
        _b.SomeMethod();
    }
}

该页面上还说明了其他两种交替模式.
