我正在尝试获取远程计算机路径上的文件夹结构和每个文件夹大小。我能够获取文件夹结构，但无论我指定的任何文件夹路径如何，文件夹大小都会返回 901.00 KB 的标准数字。我可以看到脚本能够正确获取远程文件夹路径，但不能正确获取文件/文件夹大小。

这是我到现在为止想出的代码。

param(
    [Parameter(ValueFromPipeline=$True, Mandatory=$True)]
    [System.String] $ComputerName,
    [Parameter(ValueFromPipeline=$True, Mandatory=$True, ValueFromPipelineByPropertyName=$true)]
    [ValidateNotNullOrEmpty()]
    [System.String] $Path
 )

function Get-FolderSize ($_ = (get-item .))  {
Process {
$RemoteServer = @($ComputerName)
ForEach($Computer in $ComputerName) {
$ErrorActionPreference = "SilentlyContinue"
$length = Invoke-Command -ComputerName $ComputerName { (Get-ChildItem $_.fullname -recurse | Measure-Object -property length -sum).sum 
} -ArgumentList $Path
$obj = New-Object PSObject
$obj | Add-Member NoteProperty Folder ($_.FullName)
$obj | Add-Member NoteProperty Length ($length)
Write-Output $obj

  }
 }
}

Function Class-Size($size)
{
 IF($size -ge 1GB) …

我试图在我的脚本中使用下面的代码片段检索远程服务器的UPTIME.

$lastboottime = (Get-WMIObject -Class Win32_OperatingSystem -ComputerName     $server -Credential $altcreds -ErrorAction SilentlyContinue).LastBootUpTime
$sysuptime = (Get-Date) - [System.Management.ManagementDateTimeconverter]::ToDateTime($lastboottime)
$uptime = "   UPTIME           :    $($sysuptime.days) Days, $($sysuptime.hours) Hours, $($sysuptime.minutes) Minutes, $($sysuptime.seconds) Seconds"

执行脚本时出现以下错误:

Exception calling "ToDateTime" with "1" argument(s): "Specified argument was out of the range of valid values.
Parameter name: dmtfDate"

我无法确定错误消息是什么参数是必需的？

谢谢!
