“ [轻量级功能]”在调用堆栈中 [英] "[Lightweight Function]" in the call stack

问题描述

我正在调试程序（VS2008），并且正在逐步执行代码行。我碰到了一条正在调用委托函数的行，并且我尝试着一步。但是，没有像我期望的那样进入该方法，而是绕过了该方法，调试器改为进入了我认为是委托调用的函数。在调用堆栈中，我期望委托方法的行将以灰色显示，其内容为 [Lightweight Function] 。

I'm debugging a program (VS2008), and I was stepping through lines of code. I came across one line where a delegate function was being called, and I tried to step into it. However, rather than stepping into the method as I expected, the method was bypassed, with the debugger instead stepping into what I assume is a function called by the delegate. In the call stack, the line where I expected the delegate method to be is greyed out with the text [Lightweight Function].

轻量级功能部分是什么意思？有没有办法进入此功能？

What does the "Lightweight Function" part mean? Is there a way to step into this function?

推荐答案

我相信轻量级功能是指 DynamicMethod ，即在运行时发出，使用然后卸载的一种

I believe a lightweight function refers to a DynamicMethod, i.e. one that is emitted at runtime, used, and then unloaded.

此博客文章与Iron Python有关，但该信息对于任何.NET项目都应该是有用的：查看发射的IL 。作者向您展示了如何使用较低级别的调试器（windbg.exe）来查看这些轻量级函数。

This blog post is related to Iron Python, but the information should be good for any .NET project: Viewing Emitted IL. The author shows you how to use a lower level debugger (windbg.exe) to see these "lightweight functions."
