PowerShell Pscx Expand-Archive方法故障检测 [英] PowerShell Pscx Expand-Archive method failure detection

问题描述

PowerShell片段：

PowerShell snippet:

Import-Module Pscx
Expand-Archive ConsoleApplication1.zip ./
Write-Host $?
Write-Host $LastExitCode

$都不？或 $ LastExitCode 报告有关错误。但是有错误，因为文件ConsoleApplication1.exe被锁定（我启动了此应用程序）。我可以通过以下输出看到失败：

Neither $? nor $LastExitCode report about error. But there is error, because file ConsoleApplication1.exe is locked (i started this app). I can see failure by following output:

WARNING: ArchiveCallBack->GetStream error: System.IO.IOException:
The process cannot access the file 'D:\tmp\ConsoleApplication1.exe'
 because it is being used by another process.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
...

问题：如何在Powershell中检测到Expand-Archive失败

Question: how can I detect in powershell that Expand-Archive failed

谢谢

推荐答案

好像我找到了可行的解决方案：

Looks like I've found solution that works:

$w = $null
Expand-Archive ConsoleApplication1.zip ./ -WarningVariable w

如果错误发生（或称警告），它们收集在$ w变量中。如果 $ w.Count -gt 0 表示发生了一些错误/警告。

If error occurs (or call them warnings) they are collected in $w variable. If $w.Count -gt 0 it means some error/warning have occured.
