Export-Csv 导出列表属性而不是内容答案

【问题标题】：Export-Csv Exporting List Properties Instead of ContentExport-Csv 导出列表属性而不是内容
【发布时间】：2021-04-02 16:11:20
【问题描述】：

我正在尝试将列表导出到 CSV 文件。输出应该如下所示：

Computer Name	BIOS	Operating System	Version	Disk Number	Size (GB)	Partition Type
DEVICE1	UEFI	Microsoft Windows 10 Pro	10.0.19042.0	0	954	GPT
DEVICE1	UEFI	Microsoft Windows 10 Pro	10.0.19042.0	1	119	GPT
etc...

但是，CSV 文件中的输出如下所示：

Count	Length	LongLength	Rank	SyncRoot	IsReadOnly	IsFixedSize	IsSynchronized
2	2	2	1	System.Object[]	FALSE	TRUE	FALSE

相关代码

$Result = New-Object System.Collections.Generic.List[System.Object]

#Irrelevant Code...
foreach($Device in $Devices){
#More irrelevant code...

Write-Host "`tCompiling device information... " -NoNewline
try{
    $Cmd = Invoke-Command -Session $Session -ScriptBlock{
        Get-Disk | Foreach-Object{
            [PSCustomObject]@{
                "Computer Name"    = $env:COMPUTERNAME
                "BIOS"             = if (Test-Path HKLM:\System\CurrentControlSet\control\SecureBoot\State) {"UEFI"} else {"Legacy"}
                "Operating System" = Get-WmiObject -Class Win32_OperatingSystem | Select-Object -ExpandProperty Caption
                "Version"          = [Environment]::OSVersion | Select-Object -ExpandProperty Version
                "Disk Number"      = $_.number
                "Size (GB)"        = [int]($_.size/1GB)
                "Partition Type"   = $_.PartitionStyle
            }
        }
    
    }
    $Cmd = $Cmd | Select * -ExcludeProperty PSComputerName, RunspaceId 
    $Result.Add($Cmd)
    Write-Host "Success" -ForegroundColor Green
}catch{
    Write-Host "Failed" -ForegroundColor Red
    $Result.Add(
        [PSCustomObject]@{
            "Computer Name"    = $Device
            "BIOS"             = $QueryErrorMsg
            "Operating System" = $QueryErrorMsg
            "Version"          = $QueryErrorMsg
            "Disk Number"      = $QueryErrorMsg
            "Size (GB)"        = $QueryErrorMsg
            "Partition Type"   = $QueryErrorMsg
        }
    )
    Continue
}finally{
    Remove-PSSession $Session
    Write-Host "`tConnection terminated."
}
$Count++
}

if($DisplayResults){
    $Result | ft -a
}

if($ExportToCsv){
    $Result | Export-Csv -Path ($OutputDirectory + "\DiskPartitionAudit $((Get-Date).ToString('MM-dd-yyyy hh-mm-ss tt')).csv") -NoTypeInformation
}

有什么办法可以解决这个问题吗？谢谢！

【问题讨论】：

如果您已经定义了自己的 PSCustomObject 属性，为什么还要$Cmd = $Cmd | Select * -ExcludeProperty PSComputerName, RunspaceId？
如果我没有在其中包含它，而不是在导出或显示$Result 时，那么这些属性将包含在我的输出中。接受的答案为我解决了这个问题。
@iRon 因为 Invoke-Command 会为您添加这些内容。您知道，为了您的方便。我一直讨厌这样。即使是 -HideComputerName 你仍然可以得到一个 psscomputername 属性！

问题是您要将$cmd 中收集的所有记录作为单个对象添加到$result。相反，请使用AddRange()。当我在我的 csvs 中获取 PSComputerName 和 PSShowComputerName 时，我还更改了选择对象

$Result = New-Object System.Collections.Generic.List[System.Object]

#Irrelevant Code...
foreach($Device in $Devices){
#More irrelevant code...

Write-Host "`tCompiling device information... " -NoNewline
try{
    $Cmd = Invoke-Command -Session $Session -ScriptBlock{
        Get-Disk | Foreach-Object{
            [PSCustomObject]@{
                "Computer Name"    = $env:COMPUTERNAME
                "BIOS"             = if (Test-Path HKLM:\System\CurrentControlSet\control\SecureBoot\State) {"UEFI"} else {"Legacy"}
                "Operating System" = Get-WmiObject -Class Win32_OperatingSystem | Select-Object -ExpandProperty Caption
                "Version"          = [Environment]::OSVersion | Select-Object -ExpandProperty Version
                "Disk Number"      = $_.number
                "Size (GB)"        = [int]($_.size/1GB)
                "Partition Type"   = $_.PartitionStyle
            }
        }
    } -HideComputerName 

    $Result.AddRange($Cmd)

    Write-Host "Success" -ForegroundColor Green
}catch{
    Write-Host "Failed" -ForegroundColor Red
    $Result.Add(
        [PSCustomObject]@{
            "Computer Name"    = $Device
            "BIOS"             = $QueryErrorMsg
            "Operating System" = $QueryErrorMsg
            "Version"          = $QueryErrorMsg
            "Disk Number"      = $QueryErrorMsg
            "Size (GB)"        = $QueryErrorMsg
            "Partition Type"   = $QueryErrorMsg
        }
    )
    Continue
}finally{
    Remove-PSSession $Session
    Write-Host "`tConnection terminated."
}
$Count++
}

if($DisplayResults){
    $Result | ft -a
}

if($ExportToCsv){
    $Result | Select * -ExcludeProperty RunspaceId,PSComputerName,PSShowComputerName |
        Export-Csv -Path ($OutputDirectory + "\DiskPartitionAudit $((Get-Date).ToString('MM-dd-yyyy hh-mm-ss tt')).csv") -NoTypeInformation
}

【讨论】：

完美，谢谢！以前没遇到过这个问题。

【解决方案2】：

您需要将“Select-Object”与属性列表一起使用：

$Result | Select-Object -Property "Computer Name", "BIOS", "Operating System", "Version", "Disk Number", "Size (GB)", "Partition Type" | Export-Csv -Path ($OutputDirectory + "\DiskPartitionAudit $((Get-Date).ToString('MM-dd-yyyy hh-mm-ss tt')).csv") -NoTypeInformation
