CSV中的單元格計算不正確。顯示錯誤的數字。獲取錯誤

Question

我想獲得一個單元格輸出另一個單元格的行的計算。有些單元格計算錯誤。

這裏是我的樣本數據：

 Total Devices Vulnerability Description  Comments 
Row1  3    Plugin:1234     Host1.Domain 
         Device Affected:   Host4.Domain 
         Host1.Domain    Host5.Domain 

---

Row2  12   Plugin:5678     Host2.Domain 
         Device Affected:   Host3.Domain 
         Host2.Domain 

應該

 Total Devices Vulnerability Description  Comments 
Row1  3    Plugin:1234     Host1.Domain 
         Device Affected:   Host4.Domain 
         Host1.Domain    Host5.Domain 

---

Row2  1   Plugin:5678     Host2.Domain 
         Device Affected:   
         Host2.Domain 

我的代碼：

＃定義我們要刪除 $ PendingRemoval = 「Host3.Domain」， 「Host6.Domain」 主機名

# Import the original data set 
$Data = Import-Csv .\Old.csv 

for($i = 0; $i -lt $data.Count; $i++) 
{ 
    # Grab all hostnames from the comments field 
    $HostNames = $Data[$i].Comments -split "`r?`n" 

    #Set Vulnerability Column Variable 
    [string]$VulnerabilityDesc = $Data[$i].'Vulnerability Description' 

    #Remove the Hostnames from Vulnerability Cells 
    foreach ($HostName in $HostNames) { 
    $VulnerabilityDesc = $VulnerabilityDesc.Replace($HostName, "") 
    } 
    $VulnerabilityDesc = $VulnerabilityDesc.Replace("Devices Affected", "") 
    $VulnerabilityDesc = $VulnerabilityDesc.TrimEnd() 
    $Data[$i].'Vulnerability Description' = $VulnerabilityDes 

    # Filter out unwanted ones 
    $HostNames = $HostNames |Where-Object {$_ -notin $PendingRemoval} 

    # Update original row 
    $Data[$i].Comments = $HostNames -join [System.Environment]::NewLine 
    $Data[$i].'Total Devices' = $HostNames.Length 
} 

# Export it to same csv 
$Data | Export-Csv .\New.csv -NoTypeInformation

對於我，它看起來像你的Import-CSV需要一個-delimiter '\t'正常工作。

您究竟在哪裏撥打.replace？
