C＃相当于Python的回溯库 [英] C# equivalent to Python's traceback library

问题描述

在这个帖子，Python已经回溯库得到一些详细的错误信息（行号，文件名...）。

C＃有类似的功能要知道什么样的文件/行号产生的例外呢？

ADDED

我想出了基于以下代码。答案

 使用系统; 
 
 // http://stackoverflow.com/questions/4474259/c-exception-handling-with-a-string-given-to-a-constructor 
 
级WeekdayException：异常{
公共WeekdayException（字符串wday）：基地（非法平日：+ wday）{} 
} 
 
类TryCatchFinally 
 {
酒店的公共静态无效的主要（）
 {
试
 {
抛出新WeekdayException（通过试抛出）; 
} 
赶上（WeekdayException weekdayException）{
 Console.WriteLine（weekdayException.Message）; 
 Console.WriteLine（weekdayException.StackTrace）; 
} 
} 
} 
  

和它给了我这个消息

 非法平日：上述<通过试
在TryCatchFinally.Main（）[0x00000]抛出;文件名不明> ：0 
  

解决方案

当你发现一个异常可以查看其堆栈跟踪，这应该给类似的结果：

 赶上（例外五）
 {
 Console.WriteLine （e.StackTrace）; 
} 
  

如果调试数据可以被加载（如果.pdb文件是在相同的目录作为可执行/你在调试模式下建立），这将包括文件名，行号。如果不是，将只包括方法名。

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

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

ADDED

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

using System;

// http://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);
        }
    }
}

And it gives me this message:

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

解决方案

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

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

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.
