如何从启动进程中捕获窗口命令结果?

Question

$features = Start-Process powershell -Verb runAs -ArgumentList "Get-WindowsOptionalFeature –Online" $features

如何将结果返回到我的$feature变量中？

Answer 1

快速而肮脏的解决方法：您可以使用临时 clixml 文件来存储 Get-WindowsOptionalFeature cmdlet 的结果：

$tempFile = [System.IO.Path]::GetTempFileName()
try
{
Start-Process powershell -Wait -Verb runAs -ArgumentList "-Command Get-WindowsOptionalFeature -Online | Export-Clixml -Path $tempFile"
$features = Import-Clixml -Path $tempFile
# Use $features
}
finally
{
if (Test-Path $tempFile)
{
Remove-Item -Path $tempFile -Force -ErrorAction Ignore
}
}
