Powershell实现捕获系统内置EXE程序的异常
支持所有版本。
当你运行控制台EXE命令,如robocopy.exe, ipconfig.exe或类似命令。你可以用Powershell获得他们引起的错误:
代码如下:
try { $current = $ErrorActionPreference $ErrorActionPreference = 'Stop' # this will cause an EXE command to emit an error # (replace with any console-based EXE command) net.exe user nonexistentUser 2>&1 $ErrorActionPreference = $current } catch { Write-Host ('Error occured: ' + $_.Exception.Message) }
要捕获错误你需要设置$ErrorActionPreference 为$stop,与此同时,你需要更改错误的输出方式添加“2>&1”
这样设置后,你就可以通过Powershell捕获.net中的错误了。
