C#:如何在调用时触发事件的方法上创建属性? [英] C#: How to create an attribute on a method triggering an event when it is invoked?

问题描述

在 C# 或 .NET 中，一般有没有办法在调用方法时触发事件的方法上创建属性?理想情况下，我将能够在调用该方法之前和之后运行自定义操作.

Is there a way in C# or .NET in general to create an attribute on a method which triggers an event when the method is invoked? Ideally, I would be able to run custom actions before and after the invocation of the method.

我的意思是这样的:

[TriggersMyCustomAction()]
public void DoSomeStuff()
{
}

我完全不知道怎么做或者如果可能的话，但是System.Diagnostic.ConditionalAttribute 可能会在后台做类似的事情.不过我不确定.

I am totally clueless how to do it or if it possible at all, but System.Diagnostic.ConditionalAttribute might do a similar thing in the background. I am not sure though.

编辑:我忘了提到，由于我的具体情况，性能并不是真正的问题.

EDIT: I forgot to mention that due to the circumstances of my specific case, performance is not really an issue.

推荐答案

我知道如何做到这一点的唯一方法是使用 PostSharp.它会对您的 IL 进行后处理，并且可以执行您要求的操作.

The only way I know how to do this is with PostSharp. It post-processes your IL and can do things like what you asked for.
