PowerShell：如何在ForEach循环中连接结果

Question

我想在第二个ForEach中分组该部分。 我该如何等效$ result = $ result + ...？

$clusters = "cluster1", "cluster2"
ForEach ($item in $clusters)
{
  $clusterNodes = Get-ClusterNode -Cluster $item  ;
  $clusterNodes|select Cluster,NodeName, State|Sort-Object NodeName|Format-Table -Wrap -AutoSize;

  ForEach ($vm in $clusterNodes)
  {
    $result = Get-VM -ComputerName $vm.Name |select VMName, ComputerName, PrimaryOperationalStatus, State, Path, CreationTime, Uptime, IntegrationServicesVersion,ProcessorCount, DynamicMemoryEnabled, MemoryMinimum,MemoryMaximum     |Sort-Object VMName|Format-Table -Wrap -AutoSize;
    $result
  }
}

例如，在我的输出中，每个部分都有其自己的结果。 我想组合结果，对其进行排序，计数，并将其显示为一个结果，而不是$ clusters数量的x倍。

Answer 1

您将多次执行Format-Table ，因此每次都会获得一组新的格式化输出。 代替使用包含Format-Table过滤器的foreach ，在末尾使用带有Format-Table的单个管道。

另外，您的代码中有几个冗余：

• 无需先选择 ，然后通过管道传递给Format-Table 。 您可以只在Format-Table语句中列出要输出的属性。
• 除非您计划在代码的其他位置重用这些结果，否则无需将结果分配给变量。 如果只想输出一次结果，则省略对变量的赋值，结果将自动发送到标准输出流。

用以下内容替换内部的foreach循环：

$clusterNodes | %{Get-VM -ComputerName $_.Name} | Sort-Object VMName `
| Format-Table -Wrap -AutoSize VMName, ComputerName, PrimaryOperationalStatus, State, Path, CreationTime, Uptime, IntegrationServicesVersion,ProcessorCount, DynamicMemoryEnabled, MemoryMinimum,MemoryMaximum
