不寻常的反思问题 [英] An unusual reflection question

问题描述

想象一个抽象基类 Base ，它暴露了几个受保护的构造函数Base（），Base（string）和Base（int）。

Imagine an abstract base class Base that exposes several protected constructors Base(), Base(string) and Base(int).

然后想象来自 Base 的派生类，名为 Derived ，它实现了构造函数Derived（）：base（）和Derived（string）：base（string）但是
不派生（int）：base（int）。

Then imagine a derived class from Base called Derived that implements constructors Derived():base() and Derived(string):base(string) but not Derived(int):base(int).

是否可以使用反射一般创建派生
的实例为如果有 Derived （int）：base（int）？

Is it possible using reflection to generically create an instance of Derived as if there were a Derived(int):base(int)?

创建方法为T CreateInstance< T>（int）其中T：基础

The create method being T CreateInstance<T>(int) where T : Base

在每个派生构造函数中，除了调用相应的基础构造函数之外，还有无处理。

In each of the Derived constructors there is no processing other than invoking the corresponding base constructor.

我的代码适用于由 Derived
实现的所有构造函数，但我还需要以某种方式"假装" Derived 也实现了Derived（int）：base（int）。我的代码使用反射来获取相关的Derived构造函数然后调用它，但是如果构造函数实际上没有在
Derived 中实现（但存在于基础中）我没有尝试过（但是）

My code works fine for all constructors that are implemented by Derived but I need to somehow also "pretend" that Derived also implements Derived(int):base(int) too. My code uses reflection to get the relevant Derived constructor and then calls it but in the case of a constructor not actually implemented in Derived (but present in the base) I haven't tried (yet).

如果这是不可能，FormatterServices.GetUninitializedObject（）是否有用？

If this is not possible, might FormatterServices.GetUninitializedObject() be of use?

推荐答案

我还没试过它要么，但我认为它应该工作。你为什么不尝试看看......

I haven't tried it either, but I think it should work. Why don't you try it and see ....
