是否可能在运行时扩展或修改C＃类的代码？

Is it possible to extend or modify the code of a C# class at run-time?

不可以在.NET中执行此操作。您可以编写派生类和覆盖方法（如果它们是虚拟的），但是不能修改现有类。想象一下，如果您所要求的是可能的：您可以修改一些现有系统类的行为，如System.String。

No it is not possible to do this in .NET. You could write derived classes and override methods (if they are virtual) but you cannot modify an existing class. Just imagine if what you were asking was possible: you could modify the behavior of some existing system classes like System.String.

您还可以查看扩展方法将功能添加到现有类。

You may also take a look at Extension methods to add functionality to an existing class.
