在 PowerShell 中正确拆分所选数据和格式

Question

到目前为止，我已经在 PowerShell 脚本下创建了。

$myEsxis = Get-VMHost | Select Name,DatastoreIdList,ConnectionState -First 5
 $myEsxiHosts = @()
 foreach ($myEsxi in $myEsxis)
 { Try { $obj = New-Object psobject -Property @{
          "ESXiName" = ($myEsxi).Name
          "ClusterName" = (Get-Cluster -VMHost ($myEsxi).Name).Name
          "ConnectionState" = ($myEsxi).ConnectionState
          "PingState" = Test-Connection ($myEsxi).Name -ErrorAction 0 -Quiet -Count 1
          "PhyNIC" = ((Get-EsxCli -VMHost ($myEsxi).Name).network.nic.list() | Select @{ Name = 'NIC';  Expression = {"$($_.Name)/$($_.Speed)/$($_.LinkStatus)"}} ) -split(";")
          "NumVMs" = (Get-VM -Location ($myEsxi).Name).count
          "ConnectedDatastores" = foreach ($obj in ($myEsxi).DatastoreIdList) {Get-Datastore | Where {($_.Id -eq $obj) -and ($_.Name -notlike '*local*')} | Select-Object -ExpandProperty Name}
          "ESXiVersion" = (Get-VMHost -Name ($myEsxi).Name).ExtensionData.Config.Product.FullName
         }
       }

   Catch { $obj = New-Object psobject -Property @{
           "ESXiName" = ($myEsxi).Name
           "ClusterName" = $_.Exception.Message
           "ConnectionState" = $_.Exception.Message
           "PingState" = Test-Connection ($myEsxi).Name -ErrorAction 0 -Quiet -Count 1
           "NumVMs" = $_.Exception.Message
           "PhyNIC" = $_.Exception.Message
           "ConnectedDatastores" = $_.Exception.Message
           "ESXiVersion" = $_.Exception.Message
           }
         }
 $myEsxiHosts += $obj | Sort-Object -Property ESXiName | Select ESXiName,ClusterName,PingState,ConnectionState,NumVMs,@{Name='ConnectedDatastores';Expression={[string]::join(";", ($_.ConnectedDatastores))}},@{Name='PhysicalNIC';Expression={[string]::join(";", ($_.PhyNIC))}},ESXiVersion
 }
 $myEsxiHosts

我有以下相关问题：

1. ConnectedDatastores 列给出了用分号分隔的连续输出数据，我尝试了Split() 以各种方式但没有成功。
2. PhysicalNIC 列还使用 @{ 提供相同类型的连续输出数据，我也无法消除。

我需要 ConnectedDatastores 列以在新行中显示每个项目。
我需要与 PhysicalNIC 输出相同但没有 @{

试试这个，它应该可以工作：

$myEsxis = Get-VMHost | Select Name,DatastoreIdList,ConnectionState -First 5

# Using Generic List for efficiency
$myEsxiHosts = [system.collections.generic.list[pscustomobject]]::new()

# Wrapping the oneliners inside scriptblocks for readability
$phyNIC={
        ((Get-EsxCli -VMHost $myEsxi.Name).Network.NIC.List() |
        Select @{
            Name = 'NIC'
            Expression = {"$($_.Name)/$($_.Speed)/$($_.LinkStatus)"}
        }).NIC
}

$dataStores={
    foreach ($obj in $myEsxi.DatastoreIdList)
    {
        (Get-Datastore | Where {($_.Id -eq $obj) -and ($_.Name -notlike '*local*')}).Name
    }
}

foreach ($myEsxi in $myEsxis)
{
    Try
    {
        $myEsxiHosts.Add(
            [pscustomobject]@{
                ESXiName = $myEsxi.Name
                ClusterName = (Get-Cluster -VMHost $myEsxi.Name).Name
                ConnectionState = $myEsxi.ConnectionState
                PingState = Test-Connection $myEsxi.Name -ErrorAction 0 -Quiet -Count 1
                PhyNIC = & $phyNIC | Out-String # Executing the scriptblock with '&' and piping the result to Out-String to get our multiline string
                NumVMs = (Get-VM -Location $myEsxi.Name).count
                ConnectedDatastores = & $dataStores | Out-String
                ESXiVersion = (Get-VMHost -Name $myEsxi.Name).ExtensionData.Config.Product.FullName
        })
    }
    Catch
    {
        $myEsxiHosts.Add(
            [pscustomobject]@{
                ESXiName = $myEsxi.Name
                ClusterName = $_.Exception.Message
                ConnectionState = $_.Exception.Message
                PingState = Test-Connection $myEsxi.Name -ErrorAction 0 -Quiet -Count 1
                NumVMs = $_.Exception.Message
                PhyNIC = $_.Exception.Message
                ConnectedDatastores = $_.Exception.Message
                ESXiVersion = $_.Exception.Message
        })
    }
}

$myEsxiHosts | Sort-Object -Property ESXiName 

编辑：我可能是错的，但大多数时候当我看到这个问题时，它与数据的导出方式（CSV、Xlsx 等）有关。拥有数组属性的问题是，当我们想要导出对象时，您将获得如下所示的类型，而不是显示所述属性的内容。有几种解决方法，即-join，如果你想要一个包含所有值的字符串，Out-String，如果你想让你的数组显示为多行字符串。

网上有很多比我能给你更好的解释，即：

• Getting "System.Collections.Generic.List`1[System.String]" in CSV File export when data is okay on screen
• https://www.millersystems.com/powershell-exporting-multi-valued-attributes-via-export-csv-cmdlet/

数组属性：

数组转换为多行字符串：

编辑：

如果对象被转换为 HTML，而不是使用Out-String，您需要使用-join '<br>'，然后在对象转换为 HTML 之后，您需要将'<br>' 替换为'<br>'。这在这里得到了很好的解释：Break lines in powershell array and then convert it to html?

作为一个测试示例，你可以试试这个：

(@(
[PSCustomObject]@{
    Name = 'Value'
    Arr = 1,2,3,4,5,6|Out-String
}

[PSCustomObject]@{
    Name = 'Value2'
    Arr = 1,2,3,4,5,6|Out-String
}

[PSCustomObject]@{
    Name = 'Value'
    Arr = 1,2,3,4,5,6 -join "<br>"
}

[PSCustomObject]@{
    Name = 'Value2'
    Arr = 1,2,3,4,5,6 -join "<br>"
})|ConvertTo-Html) -replace '&lt;br&gt;','<br>' > ./test.html

看起来像这样：

@santiago-squarzon 帮助我从报告中删除了 @、{ 和 ;。
但是，我能够使用 CSS white-space: break-spaces; 打破界限。
