我可以继承构造函数吗？ [英] Can I inherit constructors?

问题描述

我知道不可能在C＃中继承构造函数，但是可能有一种方法可以做我想做的事情。

I know it's not possible to inherit constructors in C#, but there's probably a way to do what I want to do.

我有一个继承的基类由许多其他类组成，它具有 Init 方法，该方法使用1参数进行一些初始化。所有其他继承类也都需要初始化，但是我需要为它们创建单独的构造函数，例如：

I have a base class that is inherited by many other classes, and it has an Init method that does some initializing taking 1 parameter. All other inheriting classes also need this initializing, but I'd need to create separate constructors for all of them that would like like this:

public Constructor(Parameter p) {
    base.Init(p);
}

这完全违反了DRY原则！

That totally violates the DRY principles! How can I have all necessary stuff initialized without creating dozens of constructors?

推荐答案

您无需创建许多构造函数就可以初始化所有必需的东西吗？全部具有相同的代码；您只创建一个，但是派生类调用了基本构造函数：

You don't need to create loads of constructors, all with the same code; you create only one, but have the derived classes call the base constructor:

public class Base
{
    public Base(Parameter p)
    {
        Init(p)
    }

    void Init(Parameter p)
    {
        // common initialisation code
    }
}

public class Derived : Base
{
    public Derived(Parameter p) : base(p)
    {
 
    }
}
