根据我的评论，我会改用Get-BitLockerVolume它，因为它返回一个更容易查询的对象：

Get-BitLockerVolume -MountPoint C: | Select-Object -ExpandProperty ProtectionStatus

我使用类似于上面帖子的内容来确定是否已通过制造商的驱动器启用了 BitLocker，该驱动器在标识字段中始终具有未知或没有。

# Check for OEM configuration of BitLocker

$blidfield = manage-bde -status C: | Select-String 'Identification Field'
$bloemencrypted = manage-bde -status C: | Select-String 'Conversion Status'
if ($blidfield -match 'None' -or $blidfield -match 'Unknown' -and ($bloemencrypted -match 'Fully Encrypted' -or $bloemencrypted -match 'Used Space Only Encrypted')){
    Write-Log "BitLocker appears to be configured with OEM configuration, Starting to decrypt."
    manage-bde -off C:
    exit
} else {
    Write-Log "BitLocker doesn't appear to be configured with OEM configuration"
}

请注意，“manage-bde -off C:”行将解密操作系统驱动器。

如果我理解正确，您想检查它是否在保护状态下匹配关闭？如果是这样，这是我快速完成的一段丑陋的代码，但可以得到你想要的：

$status = manage-bde -status C: | Select-String 'Protection'
if ($status -match 'Off'){
Write-Output $true
} else {
Write-Host $false
}
