详细异常消息(C#) [英] Verbose Exception Message (C#)

问题描述

我已经设置了一些代码来在我的C#Web应用程序中记录错误，这很好用，但是我想要一些额外的信息.

当我在Web浏览器中查看异常时，它会向我显示引发错误的行号，并且通常是周围代码的一些摘录.

在我的日志中，此消息丢失.

我试过了:

Hi,

I have setup some code to log errors in my c# web app which works great but I want some extra info.

When I view an exception in the web browser it shows me the line number that threw the error and usually a little excerpt of the surrounding code.

In my logs this message is missing.

I have tried:

ex.Message
ex.Message
ex.Source
ex.TargetSite
ex.StackTrace
Environment.StackTrace

这构成了异常的大多数信息，但是我不知道要获得消息的一部分，而行号和代码摘录正是我真正需要的.

有人知道如何访问此信息吗?我一直在尝试搜索此信息，但找不到任何涵盖它的信息.

This makes up most of the information of the exception but I don''t know to get the part of the message with the line number and excerpt of code which to be honest is all I really need.

Anyone know how to access this info? I have been trying to google this info but cant find anything that covers it.

推荐答案

您需要的是System.Exception.Stack，以一个字符串的形式.另外，通常应该递归获取System.Exception.InnerException(因为InnerException，如果不为null，也是Exception).要获得更多，请使用System.Environment.StackTrace.创建StackTrace的实例以及捕获异常的位置；您可以将堆栈帧(一次不需要全部)或一次全部堆栈起来；分别使用GetFrame或GetFrames.

参见System.Exception:
http://msdn.microsoft.com/en-us/library/system.exception.aspx [ ^ ].

System.Diagnostics.StackTrace:

如果您已经了解所有相关的班级和成员，我不知道您怎么看不到所有这些可能性.

What you need is System.Exception.Stack, in the form of one string. Also, you should generally get System.Exception.InnerException, recursively (because InnerException, if not null, is also Exception). To get a lot more, use System.Environment.StackTrace. Create an instance of StackTrace and the point where an exception was caught; you can get the stack frames on-by-one (good when you don''t need them all) or all at once; use GetFrame or GetFrames, respectively.

See System.Exception:
http://msdn.microsoft.com/en-us/library/system.exception.aspx[^].

System.Diagnostics.StackTrace:
http://msdn.microsoft.com/en-us/library/system.diagnostics.stacktrace.aspx[^].

I have no idea how you failed to see all that possibilities if you already knew all the relevant classes and members.
