推荐答案

MethodInfo是一个抽象类，因此您的问题不能直接回答.最常见的情况是，您获得了带有反射的引用，并获得了RuntimeMethodInfo实例.是的，它具有对Equals()方法以及GetHashCode()的精心重写.它处理了通用方法的特殊情况.链接的博客文章仅与GetCurrentMethod()有关.使用调试器查找具体的类类型.

MethodInfo is an abstract class so your question is not directly answerable. The most common case is where you obtained a reference with Reflection, you get a RuntimeMethodInfo instance. And yes, it has an elaborate override for the Equals() method, as well as GetHashCode(). It deals with the special case of the method being generic. The linked blog post is only relevant for GetCurrentMethod(). Use the debugger to find the concrete class type.
