如何将Powershell异常描述放入字符串中？ [英] How can I get powershell exception descriptions into a string?

问题描述

当您将错误记录发送到输出流时，我希望访问Powershell打印的相同消息

I want to have access to the same message that Powershell prints when you send an error record to the output stream

示例：

这是例外消息，位于
C：\Documents和
Settings\BillBillington\Desktop\psTest\exThrower.ps1： 1
char：6
+掷<<<< （新对象ArgumentException（这是
异常））；
+ CategoryInfo：OperationStopped：（:) []，
ArgumentException
+ FullyQualifiedErrorId：这是例外情况

This is the exception message At C:\Documents and Settings\BillBillington\Desktop\psTest\exThrower.ps1:1 char:6 + throw <<<< (New-Object ArgumentException("This is the exception")); + CategoryInfo : OperationStopped: (:) [], ArgumentException + FullyQualifiedErrorId : This is the exception

当我通过执行$ Error [0]获得最后的ErrorRecord时，我似乎无法弄清楚如何以简单的方式获取此信息

I when a get the last ErrorRecord by doing $Error[0] I can't seem to figure out how to get this information in a simple way

我从社区扩展这里可以大致执行我想要的操作，但是它会打印大量不需要的东西的半格式列表，然后我就必须剥离

I found this 'Resolve-Error' function from the community extensions here which does roughly what I want but it prints a huge semi-formatted list of stuff I don't need that I have to then strip

是否可以访问Powershell使用的消息，或者无法通过一种更简单的方式来获取我关心的值的散列，从而可以将它们放入我选择的格式的字符串中？

Is there way of accessing the message that Powershell uses or failing that a simpler way of getting hash of the values I care about so I can put them into a string in a format of my choosing?

推荐答案

如果您想要一条比@tomasr短的消息（有时对用户更友好？），建议这样做：

If you want a bit shorter message (more user friendly sometimes?) than @tomasr suggests this will do:

$error[0].ToString() + $error[0].InvocationInfo.PositionMessage

您将得到类似的内容：

Cannot find path 'C:\TEMP\_100804_135716\missing' because it does not exist.
At C:\TEMP\_100804_135716\test.ps1:5 char:15
+   Get-ChildItem <<<<  missing

此技术信息将被排除：

+ CategoryInfo          : ObjectNotFound: (C:\TEMP\_100804_135716\missing:String) [Get-ChildItem], ItemNotFoundException
+ FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.GetChildItemCommand
