Question

那么近，但是到目前为止...

我正在尝试使用[ADSI]和PowerShell在Windows服务器上更改本地管理员密码，但是我找不到在调用时传递字符串变量并出现以下错误的方法：

Exception calling "Invoke" with "2" argument(s): "Number of parameters specified does not match the expected number."
+ CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : DotNetMethodTargetInvocation
+ PSComputerName        : vmdeploytest1

这有效，并在语句中使用字符串：

$vmName = "vmdeploytest1"

Invoke-Command -ComputerName $vmName -Credential $creds -ScriptBlock {
  $account = [ADSI]("WinNT://localhost/Administrator,user")
  $account.psbase.invoke("setpassword","Password123")
}

这不是：

$vmName = "vmdeploytest1"   
$password = '"Password123"'
$invoke = '"setpassword",'
$invokeStr = $invoke + $password

Invoke-Command -ComputerName $vmName -Credential $creds -ScriptBlock {
$account = [ADSI]("WinNT://localhost/Administrator,user")
$account.psbase.invoke($invokeStr)
}

这不是

$vmName = "vmdeploytest1"   
$password = '"Password123"'

Invoke-Command -ComputerName $vmName -Credential $creds -ScriptBlock {
$account = [ADSI]("WinNT://localhost/Administrator,user")
$account.psbase.invoke("setpassword",$password)
}

这不是：

$vmName = "vmdeploytest1"   
$password = 'Password123'

Invoke-Command -ComputerName $vmName -Credential $creds -ScriptBlock {
$account = [ADSI]("WinNT://localhost/Administrator,user")
$account.psbase.invoke("setpassword",$password)
}

全部给出相同的错误。我需要能够使用变量，因为我将生成一个随机密码。

Jeroen Mostert是正确的

将变量传递到ScriptBlock中时，需要在变量前加上$using:

例如：

$vmName = "vmdeploytest1"   
$password = 'Password123'

Invoke-Command -ComputerName $vmName -Credential $creds -ScriptBlock {
$account = [ADSI]("WinNT://localhost/Administrator,user")
$account.psbase.invoke("setpassword",$using:password)
}

使用PowerShell和[ADSI]远程设置Windows本地管理员密码
