利用来自同步哈希表（Runspacepool 6000+客户端）的结果

调整脚本以执行多个功能，从测试连接开始收集数据，将会遇到6000多台机器，因此我使用的是从以下站点改编的RunspacePools;

http://learn-powershell.net/2013/04/19/sharing-variables-and-live-objects-between-powershell-runspaces/

数据如下所示，我想把它分成一个数组（我认为这是术语），所以我可以通过结果对数据进行排序。这将适用于从序列号到IAVM数据的任何其他功能。

有什么方法可以使用逗号分隔的数据并让它将下面的值吐出到列中？ IE 

Name    IPAddress    ResponseTime    Subnet
x        qwe           qweeqwe        qweqwe

此时添加的值并不重要，只是能够添加值并将其拉出来。 

Name                           Value

当您使用运行空间时，您可以为运行空间编写脚本块，就像对函数一样。您可以将要返回的任何内容写入管道，然后将其分配给变量，将其传递给另一个cmdlet或函数，或者只是将其输出到控制台。不同之处在于，虽然函数会自动返回结果，但它们会在运行空间输出缓冲区中收集它们的运行空间，并且在运行空间句柄上执行.EndInvoke（）之前不会返回。

作为一般规则，Powershell脚本的目标是（或应该）创建对象，使用运行空间的目的是通过多线程加速进程。您可以将字符串数据从运行空间返回到主脚本，然后使用它在那里创建对象，但这将是一个单线程进程。在运行空间中创建对象，以便它也是多线程的。

这是一个示例脚本，它使用一个运行空间池来执行C类子网的ping操作：

Param (
 [int]$timeout = 200
 )

 $scriptPath = (Split-Path -Path $MyInvocation.MyCommand.Definition -Parent)


While (
        ($network -notmatch "\d{1,3}\.\d{1,3}\.\d{1,3}\.0") -and -not
        ($network -as [ipaddress])
       )

   { $network = read-host 'Enter network to scan (ex. 10.106.31.0)' }

$scriptblock = 
{
  Param (
   [string]$network,
   [int]$LastOctet,
   [int]$timeout
   )

  $options = new-object system.net.networkinformation.pingoptions
  $options.TTL = 128
  $options.DontFragment = $false
  $buffer=([system.text.encoding]::ASCII).getbytes('a'*32)
  $Address = $($network.trim("0")) + $LastOctet
  $ping = new-object system.net.networkinformation.ping
  $reply = $ping.Send($Address,$timeout,$buffer,$options)

  Try { $hostname = ([System.Net.Dns]::GetHostEntry($Address)).hostname }
  Catch { $hostname = 'No RDNS' }

  if ( $reply.status -eq 'Success' )
    { $ping_result = 'Yes' }

   else { $ping_result = 'No' }

  [PSCustomObject]@{
   Address = $Address
   Ping    = $ping_result
   DNS     = $hostname
   }
}

$RunspacePool = [RunspaceFactory]::CreateRunspacePool(100,100)
$RunspacePool.Open()
$Jobs = 
   foreach ( $LastOctet in 1..254 )
    {
     $Job = [powershell]::Create().
            AddScript($ScriptBlock).
            AddArgument($Network).
            AddArgument($LastOctet).
            AddArgument($Timeout)
     $Job.RunspacePool = $RunspacePool

     [PSCustomObject]@{
      Pipe = $Job
      Result = $Job.BeginInvoke()
     }
}

Write-Host 'Working..' -NoNewline

Do {
   Write-Host '.' -NoNewline
   Start-Sleep -Seconds 1
} While ( $Jobs.Result.IsCompleted -contains $false)

Write-Host ' Done! Writing output file.'
Write-host "Output file is $scriptPath\$network.Ping.csv"

$(ForEach ($Job in $Jobs)
{ $Job.Pipe.EndInvoke($Job.Result) }) |
 Export-Csv $scriptPath\$network.ping.csv -NoTypeInformation

$RunspacePool.Close()
$RunspacePool.Dispose()

runspace脚本对每个地址执行ping操作，如果ping成功，ping会尝试从DNS解析主机名。然后，它从该数据构建一个自定义对象，并输出到管道。最后，当在运行空间作业上完成.EndInvoke（）并将其直接传送到Export-CSV时，会返回这些对象，但它可以很容易地输出到控制台，或保存到变量中。
