如何让Do-While Loop在基于网络的PowerShell脚本中工作？

问题描述：

谢谢所有帮我弄清楚发生了什么的人。如何让Do-While Loop在基于网络的PowerShell脚本中工作？

我正在使用的代码搜索猪品种的响应并验证响应不是垃圾。如果它是垃圾，do循环根据响应重复或退出。

#Get the location of this script 
$ScriptPath = (Split-Path $Myinvocation.MyCommand.path -Parent) 

    $TemPath = "$ScriptPath\_Template" 
    $NewTemPath = "$ScriptPath\_New_TEMPLATE" 
    $EarNotchPath = "$ScriptPath\EarNocthes" 
    $BoarPath = "$ScriptPath\_Boar_Samples" 
    $SowPath = "$ScriptPath\_Sow_Samples" 
    $GiltPath = "$ScriptPath\_Gilt_Samples" 
    $BarrowPath = "$ScriptPath\_Barrow_Samples" 
    $LittersPath = "$ScriptPath\_Litters_Samples" 

Do { 
#Create variables and collect information from user of script. 
$CUST= Read-Host 'Enter Customer Name ' 
$BoarPath= Read-Host 'Enter Selected Boar Name (example: WildHog)' 
$SowPath= Read-Host 'Enter Selected Sow Name (example: TrueBlue)' 
$HogBreeds= Read-Host 'Enter Hereford, Yorkshire, Hampshire, Duroc, China_Poland' 


#@Error Check $HogBreeds 
    If ('Hereford', 'Yorkshire', 'Hampshire', 'Duroc', 'China_Poland' -cnotcontains $HogBreeds){ 

     If ('Hereford', 'Yorkshire', 'Hampshire', 'Duroc', 'China_Poland' -contains $HogBreeds){ 
      $TextInfo = (Get-Culture).TextInfo 

      Switch ($HogBreeds) { 
       {$_ -in 'Hereford','Yorkshire','Duroc'} { $HogBreeds = $HogBreeds.ToUpper() } 
       'CHINA_Poland'  { $HogBreeds = $HogBreeds.Substring(0,7).ToUpper() + $HogBreeds.Substring(7,5).ToLower() } 
      } 
      $Restart = 'StopDoLoop' 
     } Else { 

      Write-Warning 'You didnt enter one of: Hereford, Yorkshire, Hampshire, Duroc, China_Poland or Your response was not recongized.' 
      $ANSWER = Read-Host 'Do you want to start over (Yes/No) - type Yes or No' 
      If ($ANSWER -eq 'Yes') { $Restart = 'StopDoLoop'} 
      If ($ANSWER -eq 'No') { Exit } 
     }     
    } 

} Until ($Restart -eq 'StopDoLoop')

如果我运行这段代码使用Windows PowerShell ISE Administrator的 'DO-虽然' 循环，没有任何问题执行。但是，如果我只需右键单击在PowerShell非ISE中打开的Do-While.ps1脚本，“Do-While”循环将重复并且永不中断。是什么赋予了？

您是否看到过改进代码的方法？我也想知道如何在$ Answer变量中添加一个字符串长度检查，我完全承认除了与朋友的对话外，我还没有研究过这个问题。

定义了$ EMVType吗？这将是一个大问题，因为它在你的脚本中看起来是空的。您的ISE会话范围可能会定义它，但您的脚本当然不会。 – Matt

@Matt，这是一个错字。 – Underdog

这是一个错字：“-cnotcontains”？ – rrirower

我想通了这个问题，现在我有我的代码工作，并希望给你所有的问题的解决方案。

#Run as Adminstrator 

    If (-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) 

    { 
    $arguments = "& '" + $myinvocation.mycommand.definition + "'" 
    Start-Process powershell -Verb runAs -ArgumentList $arguments 

    #Get the location of this script 
    $ScriptPath = (Split-Path $Myinvocation.MyCommand.path -Parent) 

     $TemPath = "$ScriptPath\_Template" 
     $NewTemPath = "$ScriptPath\_New_TEMPLATE" 
     $EarNotchPath = "$ScriptPath\EarNocthes" 
     $BoarPath = "$ScriptPath\_Boar_Samples" 
     $SowPath = "$ScriptPath\_Sow_Samples" 
     $GiltPath = "$ScriptPath\_Gilt_Samples" 
     $BarrowPath = "$ScriptPath\_Barrow_Samples" 
     $LittersPath = "$ScriptPath\_Litters_Samples" 

    Do { 
    #Create variables and collect information from user of script. 
    $CUST= Read-Host 'Enter Customer Name ' 
    $BoarPath= Read-Host 'Enter Selected Boar Name (example: WildHog)' 
    $SowPath= Read-Host 'Enter Selected Sow Name (example: TrueBlue)' 
    $HogBreeds= Read-Host 'Enter Hereford, Yorkshire, Hampshire, Duroc, China_Poland' 


    #@Error Check $HogBreeds 
     If ('Hereford', 'Yorkshire', 'Hampshire', 'Duroc', 'China_Poland' -cnotcontains $HogBreeds){ 

      If ('Hereford', 'Yorkshire', 'Hampshire', 'Duroc', 'China_Poland' -contains $HogBreeds){ 
       $TextInfo = (Get-Culture).TextInfo 

       Switch ($HogBreeds) { 
        {$_ -in 'Hereford','Yorkshire','Duroc'} { $HogBreeds = $HogBreeds.ToUpper() } 
        'CHINA_Poland'  { $HogBreeds = $HogBreeds.Substring(0,7).ToUpper() + $HogBreeds.Substring(7,5).ToLower() } 
       } 
       $Restart = 'StopDoLoop' 
      } Else { 

       Write-Warning 'You didnt enter one of: Hereford, Yorkshire, Hampshire, Duroc, China_Poland or Your response was not recongized.' 
       $ANSWER = Read-Host 'Do you want to start over (Yes/No) - type Yes or No' 
       If ($ANSWER -eq 'Yes') { $Restart = 'StopDoLoop'} 
       If ($ANSWER -eq 'No') { Exit } 
      }     
     } 

    } Until ($Restart -eq 'StopDoLoop') 

}

结束语我不只是我的“DO-while循环”，但我的所有代码的第一个“IF”语句解决了，我现在可以运行我的管理员PowerShell窗口中的所有代码，而无需PowerShell中的问题ISE。

我确实希望这可以帮助所有发现此贴子的人。

谢谢大家的帮助。
