为什么堆栈跟踪显示我的开发文件路径？ [英] Why does the Stack Trace shows my development files path?

问题描述

Visual Studio 2010 SP1，已编译的WCF应用程序，将其放在服务器上，当然，在第一次运行时（新功能）出现错误，将堆栈跟踪输出到日志文件。

Visual Studio 2010 SP1, compiled WCF app, put it on a server, and of course it got an error on the first run (what's new), outputted Stack Trace to log file.

正在看到通往我的开发环境的道路。为什么？是因为与Release相比，我将其部署为Debug还是有其他东西，还是我应该更小心地输出堆栈跟踪信息？

It's seeing the path to my development environment. Why? Is it because I deployed it as Debug compared to Release or is there something else, or shall I be more careful about outputting Stack Traces regardless?

推荐答案

这是因为您复制了.pdb文件以及可执行文件。 CLR在生成堆栈跟踪时将寻找它们，以尝试提供有关跟踪中堆栈帧的尽可能多的信息。 .pdb存储源文件名和行号。

It is because you copied the .pdb files as well as the executables. The CLR will look for them when it generates a stack trace to try to give as much info as possible about the stack frames in the trace. The .pdb stores the source file name and line number.

您应该部署代码的Release版本。这样可以进行优化，从而使您的代码运行更快。您仍然可以复制该版本的.pdb文件，它们通常会删除该调试信息。在Project + Properties中，切换到Release build，Build，Advanced， Debug Info设置。对于发行版本，此处的正常设置是仅pdb而不是完整。这意味着不包括源文件和行号。这很有道理，在抖动优化代码后，堆栈跟踪往往会变得不可靠。

You are supposed to deploy the Release build of your code. That enables optimizations that can make your code run a lot faster. You can still copy the .pdb files for that build, they normally have that debug info stripped. Project + Properties, switch to the Release build, Build, Advanced, "Debug Info" setting. The normal setting here for release builds is "pdb-only" instead of "full". Which implies that source file and line number is not included. Which makes sense, stack traces tend to be a bit unreliable after the jitter has optimized the code.
