可以說我有一個csv文件有5個記錄(實際上大約有80,000個)。Powershell將csv列的值拆分爲兩個單獨的列值

CSV文件:

column1,columnICareAbout,column2 
someRandomValue,John Doe - Generic,someRandomValue 
someRandomValue,Captain Teemo - pocketPet,someRandomValue 
someRandomValue,Pinky Brain - Fictional,someRandomValue 
someRandomValue,Miyamoto Musashi - swordsman,someRandomValue 
someRandomValue,Kato yasunori - troubleMaker - Extreme,someRandomValue 

考慮下面的代碼:

注:我知道數組值是正確的,我只需要知道通過表達陣列如何循環。

$firstNames = @() 
$firstNameCounter = 0 
$lastNames = @() 
$lastNameCounter = 0 

Import-Csv $file1 | 
    foreach { 
     $firstNames += $_.Description.split(" ")[0] 
     $lastNames += $_.Description.split(" ")[1] 
    } 

Import-Csv $file1 | 
    Select-Object *, @{n='First Name'; e={$firstNames[$firstNameCounter];$script:firstNameCounter++}}, @{n='Last Name'; e={$lastNames[$lastNameCounter];$script:lastNameCounter++}} | 
    Export-Csv "testresults.csv" -NoTypeInformation -Force 

我每次只能得到數組中的第一個元素。所以,最終的結果文件看起來像這樣

column1,columnICareAbout,column2,First Name,Last Name 
someRandomValue,John Doe - Generic,someRandomValue,John,Doe 
someRandomValue,Captain Teemo - pocketPet,someRandomValue,John,Doe 
someRandomValue,Pinky Brain - Fictional,someRandomValue,John,Doe 
someRandomValue,Miyamoto Musashi - swordsman,someRandomValue,John,Doe 
someRandomValue,Kato yasunori - troubleMaker - Extreme,someRandomValue,John,Doe 

我想要的文件看起來像這樣

column1,columnICareAbout,column2,First Name,Last Name 
someRandomValue,John Doe - Generic,someRandomValue,John,Doe 
someRandomValue,Captain Teemo - pocketPet,someRandomValue,Captain,Teemo 
someRandomValue,Pinky Brain - Fictional,someRandomValue,Pinky,Brain 
someRandomValue,Miyamoto Musashi - swordsman,someRandomValue,Miyamoto,Musashi 
someRandomValue,Kato yasunori - troubleMaker - Extreme,someRandomValue,Kato,yasunori 

誰能告訴我什麼,我做錯了什麼?

+1

爲什麼在兩個步驟做呢? 'Import-CSV $ File1 |選擇*,@ {l ='First Name'; e = {$ _。Description .Split('')[0]}},@ {l ='Last Name'; e = {$ _。Description.Split '')[1]}} | Export-CSV testresults.csv -NoType -Force' – TheMadTechnician

+0

與第二個循環不同,只需在第一個循環中追加屬性即可。添加成員-MemberType NoteProperty - 名字 - 值$ firstName' – skukx

+0

感謝TheMadTechnician。這工作。儘管我仍然想知道如何在表達式中遍歷數組。這會幫助我解決目前我正面臨的一個問題。 –

Import-Csv $file1 | 
foreach { 
    $firstName = $_.Description.split(" ")[0] 
    $lastName = $_.Description.split(" ")[1] 

    $_ | Add-Member -MemberType NoteProperty -Name FirstName -Value $firstName 
    $_ | Add-Member -MemberType NoteProperty -Name LastName -Value $lastName 
} | Export-Csv 'results.csv'
