我是 PowerShell 的新手，我正在尝试使用一个脚本来列出我的并行端口。我从这里获取了 PowerShell 脚本：

On Error Resume Next

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")

Set colItems = objWMIService.ExecQuery("Select * from Win32_ParallelPort")

For Each objItem in colItems
    Wscript.Echo "Availability: " & objItem.Availability
    For Each strCapability in objItem.Capabilities
        Wscript.Echo "Capability: " & strCapability
    Next
    Wscript.Echo "Description: " & objItem.Description
    Wscript.Echo "Device ID: " & objItem.DeviceID
    Wscript.Echo "Name: " & objItem.Name
    Wscript.Echo "OS Auto Discovered: " & objItem.OSAutoDiscovered
    Wscript.Echo "PNP Device ID: " & objItem.PNPDeviceID
    Wscript.Echo "Protocol Supported: " & objItem.ProtocolSupported
Next

执行脚本后，我得到：

PS C:\> .\script.ps1
Unexpected token '_' in expression or statement.
At C:\script.ps1:4 char:44
+ Set objWMIService = GetObject("winmgmts:" _ <<<<
    + CategoryInfo          : ParserError: (_:String) [], ParseException
    + FullyQualifiedErrorId : UnexpectedToken

我什至尝试更改&，$正如我在这个脚本中看到的那样，它也不起作用。是我的 PowerShell 有问题还是导致问题的脚本？

PS：我在 Windows XP 32bit 中使用 PowerShell v2.0

先感谢您！

根据答案，它不是 PowerShell 脚本，而是 vbscript。所以我现在的问题是，如果它确实是一个 PowerShell 脚本，为什么这个脚本不起作用：

$strComputer = "." 

$colItems = get-wmiobject -class "Win32_ParallelPort" -namespace "root\CIMV2" ` 
-computername $strComputer 

foreach ($objItem in $colItems) { 
      write-host "Availability: " $objItem.Availability 
      write-host "Capabilities: " $objItem.Capabilities 
      write-host "Capability Descriptions: " $objItem.CapabilityDescriptions 
      write-host "Caption: " $objItem.Caption 
      write-host "Configuration Manager Error Code: " $objItem.ConfigManagerErrorCode 
      write-host "Configuration Manager User Configuration: " $objItem.ConfigManagerUserConfig 
      write-host "Creation Class Name: " $objItem.CreationClassName 
      write-host "Description: " $objItem.Description 
      write-host "Device ID: " $objItem.DeviceID 
      write-host "DMA Support: " $objItem.DMASupport 
      write-host "Error Cleared: " $objItem.ErrorCleared 
      write-host "Error Description: " $objItem.ErrorDescription 
      write-host "Installation Date: " $objItem.InstallDate 
      write-host "Last Error Code: " $objItem.LastErrorCode 
      write-host "Maximum Number Controlled: " $objItem.MaxNumberControlled 
      write-host "Name: " $objItem.Name 
      write-host "Operating System Auto-Discovered: " $objItem.OSAutoDiscovered 
      write-host "PNP DeviceID: " $objItem.PNPDeviceID 
      write-host "Powe rManagement Capabilities: " $objItem.PowerManagementCapabilities 
      write-host "Power Management Supported: " $objItem.PowerManagementSupported 
      write-host "ProtocolS upported: " $objItem.ProtocolSupported 
      write-host "Status: " $objItem.Status 
      write-host "Status Information: " $objItem.StatusInfo 
      write-host "System Creation Class Name: " $objItem.SystemCreationClassName 
      write-host "System Name: " $objItem.SystemName 
      write-host "Time Of Last Reset: " $objItem.TimeOfLastReset 
      write-host 
}

我收到此错误：

Missing expression after unary operator '-'.

    + CategoryInfo          : ParserError: (-:String) [], ParseException

在您修改后的脚本中，第 3 行的反引号后有一个空格，因此无法识别延续。在 PowerShell 中使用反引号 to 续行时，它后面不能跟空格字符。消除该空间，或将其全部设为一行：

$colItems = get-wmiobject -class "Win32_ParallelPort" -namespace "root\CIMV2" -computername $strComputer

您的示例脚本不是 PowerShell，而是 vbscript。

PowerShell 要简单得多，您可以使用以下内容：

Get-WmiObject Win32_ParallelPort
