如何在 C# 中向类动态添加字段 [英] How can I dynamically add a field to a class in C#

问题描述

有什么方法可以在运行时将 Field(或 FieldInfo，也许是一样的)添加到类中?

Is there any way to add Field (or FieldInfo, maybe this is the same) to a class at runtime?

推荐答案

您不能在运行时更改类定义.但是，您可以创建一个继承自原始类的新类(如果它不是 sealed)并声明该字段.您可以通过使用 System.Reflection.Emit 发出适当的 IL 代码来实现这一点.

You can't alter a class definition at runtime. However, you can create a new class that inherits from the original class (if it's not sealed) and declares the field. You can do this by emitting the appropriate IL code using System.Reflection.Emit.
