从方法参考C＃得到的MethodInfo [英] get methodinfo from a method reference C#

问题描述

我们可以使用C＃的typeof 关键字，当我们想要得到的特定类型的类型实例。但我可以使用，如果我想获得的MethodInfo 的方法通过它的参考？

We can use a C# typeof keyword when we want to get Type instance for specified type. But what can I use if I want to get MethodInfo of a method by it's reference?

例如我有一个简单的控制台应用程序。它包含 Program.Main 方法。我想获得的MethodInfo 通过使用类似 methodinfoof（Program.Main）。我有这个问题，因为该方法的名称可能会改变，所以我不能只用 Type.GetMethodInfo（字符串方法名）为

For example I have a simple console app. It contains Program.Main method. I want to get MethodInfo by using something like methodinfoof(Program.Main). I have this problem because the method names might change, so I cannot just use Type.GetMethodInfo(string MethodName) for that.

我有大约10 000的方法，我想获得的MethodInfo ，因此添加任何自定义属性或其他任何以我的方法是不是一个解决方案。

I have about 10 000 methods for which I would like to get MethodInfo, so adding any custom attributes or anything else to my methods is not a solution.
