如何在PowerShell中获取错误的行号 [英] How to get the line number of error in PowerShell

问题描述

我试图在运行 PowerShell 脚本时获取错误的行号.这是我目前正在使用的:

I'm trying to get the line number of an error when running a PowerShell script. Here is what I'm using at the moment:

$e = $_.Exception
$line = $_.Exception.InvocationInfo.ScriptLineNumber
$msg = $e.Message 

Write-Host -ForegroundColor Red "caught exception: $e at $line"

有时这行得通，有时却行不通.我想知道我是否做错了什么，或者我可以做些什么来使这项工作更加一致.

Sometimes this works and sometimes it doesn't. I'm wondering if I'm doing anything wrong, or what I can do to make this work more consistently.

推荐答案

我想出了问题所在:

代替:

$e = $_.Exception
#this is wrong
$line = $_.Exception.InvocationInfo.ScriptLineNumber
$msg = $e.Message 

Write-Host -ForegroundColor Red "caught exception: $e at $line"

应该是

$e = $_.Exception
$line = $_.InvocationInfo.ScriptLineNumber
$msg = $e.Message 

Write-Host -ForegroundColor Red "caught exception: $e at $line"
