Question

我有一个有效的PowerShell脚本，可以从我们网络中的计算机上获取Windows产品密钥。该脚本在powershell命令行中运行良好，但在我尝试从C＃运行时返回错误。我需要这样做才能在我们公司中制作许可证。

Powershell代码：

function Get-WindowsKey {
$target = '$server'
$hklm = 2147483650
$regPath = "Software\Microsoft\Windows NT\CurrentVersion\DefaultProductKey"
$regValue = "DigitalProductId4"
$productKey = $null
$win32os = $null
$wmi = [WMIClass]"\\$target\root\default:stdRegProv"
$data = $wmi.GetBinaryValue($hklm,$regPath,$regValue)
$binArray = ($data.uValue)[52..66]
$charsArray = "B","C","D","F","G","H","J","K","M","P","Q","R","T","V","W","X","Y","2","3","4","6","7","8","9"
For ($i = 24; $i -ge 0; $i--) {
    $k = 0
    For ($j = 14; $j -ge 0; $j--) {
        $k = $k * 256 -bxor $binArray[$j]
        $binArray[$j] = [math]::truncate($k / 24)
        $k = $k % 24
    }
    $productKey = $charsArray[$k] + $productKey
    If (($i % 5 -eq 0) -and ($i -ne 0)) {
        $productKey = "-" + $productKey
    }
}
$productkey
}
Get-WindowsKey | Format-Table -AutoSize

只需用$替换$ server。或你的IP

运行脚本的C＃代码：

private void RunWindowsKeyScript(string IP)
{
    try
    {
        Assembly keyAssembly = this.GetType().Assembly;
        ResourceManager keyResMan = new ResourceManager("LanMap.Resources.PS script", keyAssembly);
        string keyScript = keyResMan.GetString("WindowsKey");
        keyScript = keyScript.Replace("$server", IP);
        Runspace keyRunspace = RunspaceFactory.CreateRunspace();
        keyRunspace.Open();
        Pipeline keyPipeline = keyRunspace.CreatePipeline();
        keyPipeline.Commands.AddScript(keyScript);
        keyPipeline.Commands.Add("Out-String");
        Collection<psobject> keyResults = keyPipeline.Invoke();
        keyRunspace.Close();
        StringBuilder keyStringBuilder = new StringBuilder();
        foreach (PSObject obj in keyResults)
        {
            keyStringBuilder.AppendLine(obj.ToString());
        }
    }
    catch (Exception ex)
    {
        string s = "";
        s += " ";
    }
}

如果可以，请帮忙。我已经知道错误是在C＃GetBinaryValue中返回null。我无法让它发挥作用。

Answer 1

我不确定你是如何以脚本形式使用它的：

$target = '$server'

单引号字符串不会扩展其中的变量。这应该可以正常工作：

$target = "$server"

这通常就足够了$target = $server但是因为你正在进行字符串替换，所以最好坚持使用双引号。

另一种可能性是您的C＃代码正在以x86身份运行，并且您正在读取WOW64注册表而不是64位注册表。这可以解释为什么在运行脚本和通过C＃应用程序运行之间会看到不同的结果。

更新：请参阅底部了解理论。

从ISE测试PowerShell代码：看起来GetBinaryValue失败了：

$target = 'localhost'
$hklm = 2147483650
$regPath = "Software\Microsoft\Windows NT\CurrentVersion\DefaultProductKey"
$regValue = "DigitalProductId4"
$productKey = $null
$win32os = $null
$wmi = [WMIClass]"\\$target\root\default:stdRegProv"
$data = $wmi.GetBinaryValue($hklm,$regPath,$regValue)

if ($data -eq $null) { Write-DEbug "Data is NULL"; return "STOP 2" }

write-debug '$Data'
write-debug ("$($data): " + ($data | gm | out-string))
write-debug ("$($data): " + ($data | fl * | out-string))

if ($data.uValue -eq $null) { Write-Debug "Data.uValue is NULL"; return "STOP 3" }
# rest cut for testing

结果：

DEBUG: $Data
DEBUG: System.Management.ManagementBaseObject:

ReturnValue: 2对应于ERROR_FILE_NOT_FOUND（假设ReturnValue成员反映GetBinaryValue的返回值，其中0表示成功，否则返回标准Windows API错误。）

更新

根据ISE实例，即使得到这个：

PS [32] C:\ #50> gp "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DefaultProductKey"
gp : Cannot find path 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DefaultProductKey' because it does not exist.
At line:1 char:1
+ gp "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DefaultProductKey"

    + FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.GetItemPropertyCommand

但是我可以看到密钥......但是ISE的64位实例却有效。

该密钥仅可用于（直接）64位进程，最近Visual Studio版本的默认设置是大多数应用程序构建为32位（大多数应用程序不需要额外的地址空间），32位.NET应用程序将加载32位PowerShell运行时程序集。

您是否尝试构建64位应用程序？
