或者试试这个。它将输出捕获到变量$scriptOutput:

& "netdom.exe" $params | Tee-Object -Variable scriptOutput | Out-Null

$scriptOutput

你有没有试过:

$OutputVariable = (Shell命令)| Out-String

如果你想重定向错误输出，你必须做:

$cmdOutput = command 2>&1

或者，如果程序名中有空格:

$cmdOutput = & "command with spaces" 2>&1

或者试试这个。它将输出捕获到变量$scriptOutput:

& "netdom.exe" $params | Tee-Object -Variable scriptOutput | Out-Null

$scriptOutput

我得到了以下工作:

$Command1="C:\\ProgramData\Amazon\Tools\ebsnvme-id.exe"
$result = & invoke-Expression $Command1 | Out-String

$result为您提供所需的

我使用以下方法:

Function GetProgramOutput([string]$exe, [string]$arguments)
{
    $process = New-Object -TypeName System.Diagnostics.Process
    $process.StartInfo.FileName = $exe
    $process.StartInfo.Arguments = $arguments
    
    $process.StartInfo.UseShellExecute = $false
    $process.StartInfo.RedirectStandardOutput = $true
    $process.StartInfo.RedirectStandardError = $true
    $process.Start()
    
    $output = $process.StandardOutput.ReadToEnd()   
    $err = $process.StandardError.ReadToEnd()
    
    $process.WaitForExit()
    
    $output
    $err
}
    
$exe = "C:\Program Files\7-Zip\7z.exe"
$arguments = "i"
    
$runResult = (GetProgramOutput $exe $arguments)
$stdout = $runResult[-2]
$stderr = $runResult[-1]
    
[System.Console]::WriteLine("Standard out: " + $stdout)
[System.Console]::WriteLine("Standard error: " + $stderr)
