C＃相当于Python的追溯库 [英] C# equivalent to Python's traceback library

问题描述

在这篇文章，python有追溯库，以获取一些详细的错误信息（行号，文件名...）。

In this post, python has traceback library to get some detailed error information (line number, file name ...).

C＃有类似的功能来知道什么文件/行号产生异常？

Does C# have similar functions to know what file/line number that generates the exception?

我想出了以下代码答案。

I came up with the following code based on the answers.

using System;

// https://stackoverflow.com/questions/4474259/c-exception-handling-with-a-string-given-to-a-constructor

class WeekdayException : Exception {
    public WeekdayException(String wday) : base("Illegal weekday: " + wday) {}
}

class TryCatchFinally 
{
    public static void Main() 
    {
        try
        {
            throw new WeekdayException("thrown by try");
        }
        catch(WeekdayException weekdayException) {
            Console.WriteLine(weekdayException.Message);
            Console.WriteLine(weekdayException.StackTrace);
        }
    }
}

它给我这个消息：

Illegal weekday: thrown by try
  at TryCatchFinally.Main () [0x00000] in <filename unknown>:0 

推荐答案

当您捕获异常时，您可以查看堆栈跟踪，应该给出类似的结果：

When you catch an exception you can view its stack trace, which should give similar results:

catch(Exception e)
{
    Console.WriteLine(e.StackTrace);
}

如果可以加载调试数据（如果.pdb文件是相同的目录作为可执行文件/您在调试模式下构建），这将包括文件名行行号。如果不是，它只会包含方法名称。

If debug data can be loaded (if the .pdb file is in the same directory as the executable/you build in debug mode) this will include file names line numbers. If not it will only include method names.
