用CSV導出已安裝程序的輸出

Question

我的當前項目的輸出和導出有幾個問題。我正在使用cmdlet Get-RemoteProgram通過網絡和註冊表項獲取安裝的軟件。

這是我的代碼現在：

function Get-RemoteProgram .... 

$computername = Import-Csv "C:\data\test\test.csv" | 
       select -ExpandProperty PCName 
$regex = @("Program1|Program2|Program3") 
$items = @() 

foreach ($computer in $computername) { 
    if (Test-Connection $computer -ErrorAction SilentlyContinue -Count 1) { 
    $query = Get-RemoteProgram -ComputerName $computer -Property DisplayVersion | 
      where {$_.ProgramName -match $regex} 
    $obj = New-Object -Type PSObject 
    $obj | Add-Member -Name ("Computername") -Value $computer -MemberType NoteProperty -Force 
    $maxcount = $query.ProgramName.Count 
    if ($maxcount -gt 1) { 
     for ($i=0; $i -lt $maxcount; $i++) { 
     $progandversion = $query.ProgramName[$i] + $query.DisplayVersion[$i] 
     $obj | Add-Member -Name ($progandversion) -Value "Available" -MemberType NoteProperty -Force 
     } 
    } elseif ($maxcount -eq 1) { 
     $progandversion = $query.ProgramName + $query.DisplayVersion 
     $obj | Add-Member -Name ($progandversion) -Value "Available" -MemberType NoteProperty -Force 
    } 

    $obj | Add-Member -Name ("ProgrammVersion$i") -Value $query.DisplayVersion[$i] -MemberType NoteProperty -Force 
    $items += $obj 
    } 

    $items | Export-Csv c:\daten\inventur\output_final.csv -Append -Force 
    Write-Host "$computer has been checked.." 
} 

的問題我現在已經是我的腳本沒有列出我尋找各種不同的方案。它應該導出計算機名稱，然後 - 在同一行中 - 如果安裝了該軟件，則輸出一個可用的名稱，或者如果未找到該程序，請將其保持清潔。

這就是輸出我得到現在：

 
#TYPE System.Management.Automation.PSCustomObject 
Computername,"Program1","Program2" 
Computer1,"Available","Available" 
Computer1,"Available","Available" 
Computer2,, 
Computer1,"Available","Available" 
Computer3,, 
Computer2,, 
Computer1,"Available","Available" 

我不知道爲什麼計算機在輸出多次。

我想有這樣的：

 
Computername,Program1,Program2,Program3,Program4 
Computer1,Available,,Available,, 
Computer2,Available,,,, 
Computer3,,,Available, 
Computer4,,,, 

你能幫我不知何故？

Answer 1

你的問題是雙重的。首先，您想要以CSV格式更新現有數據，但在運行Export-CSV時使用-Append。這解釋了存在給定ComputerName的多行。其次，您沒有爲給定的ProgramName設置默認值，因此輸出CSV中不存在任何地方找不到的程序的屬性。要解決您的第一個問題，您需要運行Export-CSV而不用追加將您的整個數據集保存到CSV文件中。爲了解決你的第二個問題，你應該預先填寫新的PSObject的屬性。準備應該做的是這樣的：

$programs=get-content "programs.txt" # one name one line, or an array of names in @() 
$regex='('+($programs -join ',')+')' # regex out of array 

然後在你的主循環，你調用後添加此行New-Object：

$programs | % { $obj | Add-Member -Name $_ -Value "Not found" -MemberType NoteProperty } # create default values 

應該做的。如果您願意，可以換一個空字符串「找不到」。
