Powershell - 提示用户然后在 xx 秒后过期提示

Question

我正在尝试显示用户操作提示，如果没有采取任何操作，提示关闭并继续运行脚本。这是我的命令提示符对话框配置

$yes = New-Object System.Management.Automation.Host.ChoiceDescription "&Yes",""
$no = New-Object System.Management.Automation.Host.ChoiceDescription "&No",""
$cancel = New-Object System.Management.Automation.Host.ChoiceDescription "&Cancel",""
$choices = [System.Management.Automation.Host.ChoiceDescription[]]($yes,$no,$cancel)
$caption = "Caption message here"
$dialogmessage = ("Do you want to do something?:`n")

$timer = #set some value
#While the value is grater than zero keep the prompt open

while($timer -gt 0)
{
    $result = $Host.UI.PromptForChoice($caption,$dialogmessage,$choices,0)

    if($result -eq 0){Write-Host "Yes was selected"}

    if($result -eq 1){Write-Host "No was selected"}

    if($result -eq 2){Write-Host "Canceled by user.";exit}
 }

我已经在互联网上上下看了看，我已经看到这是在 C# 中实现的，但对于我的生活，我无法确定 powershell 的最佳方法。我将不胜感激任何帮助。

谢谢

编辑:谢谢诺亚，这是更新的代码，它也更紧凑了!

        $prompt = new-object -comobject wscript.shell 
        $answer = $prompt.popup("Do you want to do something?`n",5,"title",3)              
        if($answer -eq 6) {Write-Host "Yes was selected"}
        if($answer -eq 7) {Write-Host "No was selected"}
        if($answer -eq -1) {Write-Host "Timed out"}
        if($answer -eq 2) {Write-Host "Canceled by user."}

给你...从我的一个旧脚本中挖出这个

#Value  Description   
#0 Show OK button. 
#1 Show OK and Cancel buttons. 
#2 Show Abort, Retry, and Ignore buttons. 
#3 Show Yes, No, and Cancel buttons. 
#4 Show Yes and No buttons. 
#5 Show Retry and Cancel buttons.

$a = new-object -comobject wscript.shell 
$intAnswer = $a.popup("Question?",2,"Title",4) #first number is timeout, second is display.

#7 = no , 6 = yes, -1 = timeout
