How can I get powershell exception descriptions into a string?

Question

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

Example:

This is the excep

Answer 1

Similar to @tomasr, but shorter:

$($error[0])

For all errors in a script:

$($error)

Answer 2

How about:

$x = ($error[0] | out-string)

Is that what you wanted?

Answer 3

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

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

You will get something like:

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

This technical info will be excluded:

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

Answer 4

I took it a bit further because I didn't like the multilines from $error[0].InvocationInfo.PositionMessage.

Function FriendlyErrorString ($thisError) {
    [string] $Return = $thisError.Exception
    $Return += "`r`n"
    $Return += "At line:" + $thisError.InvocationInfo.ScriptLineNumber
    $Return += " char:" + $thisError.InvocationInfo.OffsetInLine
    $Return += " For: " + $thisError.InvocationInfo.Line
    Return $Return
}

[string] $ErrorString = FriendlyErrorString $Error[0]
$ErrorString

You can look at what else is availible to construct your own String via:

$Error | Get-Member
$Error[0].InvocationInfo | Get-Member

Answer 5

Foreach ($Errors in $Error){
  #Log Eintrag wird zusammengesetzt und in errorlog.txt geschrieben
  "[$Date] $($Errors.CategoryInfo.Category) $($Errors.CategoryInfo.Activity) $($Errors.CategoryInfo.Reason) $($Errors.CategoryInfo.TargetName) $($Errors.CategoryInfo.TargetType) $($Errors.Exception.Message)" |Add-Content $Path\errorlog.txt -Encoding UTF8
}

You can also do this and you will get all Informations about the Error
