从类型名称转换为字符串 [英] Cast to a type from the type name as a string

问题描述

我有一个现有的基本类型，我想根据类型的名称将其强制转换为派生类型，即字符串，所以像这样：

I have an existing base type and I would like to cast it to a derived type base upon the name of the type as a string, so something like this:

public void DoStuffInDerivedType(string derivedName) {
   (base as Type.GetType(derivedName)).DoThisThing();
}

我很确定这是不可能完成的，但是肯定知道。谢谢

I'm pretty sure this can't be done but would be good to know for sure. Thanks

编辑：我知道我可以使用类型名称的反射来构造对象，但我想使用现有的对象。我也知道这通常是个坏主意。但是，我想将其用于SpecFlow BDD功能。

I understand that I could construct the object using reflection from the type name but I want use an existing object. And also I know this is generally a bad idea. However I wanted to use this for a SpecFlow BDD Feature.

推荐答案

我将重复您可能不需要的建议这样做，但是因为我之前已经做过此操作：

I'll repeat the advice that you probably don't need to do this, but because I have done this operation before:

Convert.ChangeType（ItemToCast，Type.GetType（stringNameOfType）））

应该为您服务。
