arrays - Powershell CSV嵌套哈希表/数组查找

我有两个CSV文件。 TeamCSV和TeamDetailsCSV。请参阅下面的格式。

我想通过使用TeamCSV(团队，名称，数字，颜色)作为基础并在TeamDetailsCSV(形状和代码)中进行一些查找来输出第三个CSV(下面的所需输出)。

但是，团队A和团队E组成一个阵列(请参见下面的BadOutputCSV)。我想按DesiredOutputCSV中的说明逐行导出thirdCSV。我在下面发布了我的代码。

感谢对此的任何帮助。现在已经裂了几天头。非常感谢大家。

PS C:\temp1> $TeamCSV

Team   Name  Number Color
----   ----  ------ -----
Team A John  1      Blue
Team A Mary  2      Blue
Team A James 5      Red
Team B Mark  5      Red
Team C Joey  3      Green
Team D Amy   3      Green
Team E Rose  4      Green
Team E Janet 2      Red

PS C:\temp1> $TeamDetailCSV

Team   Shape    Code
----   -----    ----
Team A Circle   TC01
Team B Square   TC01
Team C Triangle TC01
Team D Hexagon  TC02
Team E Pentagon TC03

PS C:\temp1> $DesiredOutput | ft

Team   Name  Number Color Shape    Code
----   ----  ------ ----- -----    ----
Team A John  1      Blue  Circle   TC01
Team A Mary  2      Blue  Circle   TC01
Team A James 5      Red   Circle   TC01
Team B Mark  5      Red   Square   TC01
Team C Joey  3      Green Triangle TC01
Team D Amy   3      Green Hexagon  TC02
Team E Rose  4      Green Pentagon TC03
Team E Janet 2      Red   Pentagon TC03

PS C:\temp1> $BadOutput | ft

Team            Name            Number          Color           Shape    Code
----            ----            ------          -----           -----    ----
System.Object[] System.Object[] System.Object[] System.Object[] Circle   TC01
Team B          Mark            5               Red             Square   TC01
Team C          Joey            3               Green           Triangle TC01
Team D          Amy             3               Green           Hexagon  TC02
System.Object[] System.Object[] System.Object[] System.Object[] Pentagon TC03

这是我的代码

    $TeamCSV = Import-Csv .\Team-conv.csv
    $TeamDetailCSV = Import-Csv .\TeamDetail-conv.csv



    $TeaminBoth = Compare-Object -ReferenceObject $TeamCSV.Team -DifferenceObject $TeamDetailCSV.team -IncludeEqual | #Posh v3
    Where-Object {$_.SideIndicator -eq "=="} |
    Select-Object -ExpandProperty InputObject

    $OutputCSV = ForEach($Team in $TeaminBoth) {
        $columnTeamCSV = $TeaminBoth | Where-Object {$_.Team -eq $Team}
        $columnTeamDetailCSV = $TeaminBoth | Where-Object {$_.Team -eq $Team}

           [PSCustomObject][Ordered] @{


                Team = $columnTeamCSV.Team
                Name = $columnTeamCSV.Name
                Number = $columnTeamCSV.Number
                Color = $columnTeamCSV.Color
                Shape = $columnTeamDetailCSV.Shape
                Code = $columnTeamDetailCSV.Code
            }



$OutputCSV | Export-CSV -NoTypeInformation -Path $xlsxPath\teamdetails.csv

最佳答案

这是使用哈希表完成此操作的一种方法:

Import-Csv .\TeamDetail.csv |
    ForEach-Object {$teamLookup=@{}}{
        $teamLookup[$_.Team] = $_
    }

Import-Csv .\Team.csv |
    ForEach-Object {
        $_ | Add-Member -MemberType NoteProperty -Name Shape -Value $teamLookup[$_.Team].Shape -PassThru |
                Add-Member -MemberType NoteProperty -Name Code -Value $teamLookup[$_.Team].Code -PassThru
    } | Export-csv .\DesiredOutput.csv

如果导入DesiredOutput.csv，则会得到:

Team   Name  Number Color Shape    Code
----   ----  ------ ----- -----    ----
Team A John  1      Blue  Circle   TC01
Team A Mary  2      Blue  Circle   TC01
Team A James 5      Red   Circle   TC01
Team B Mark  5      Red   Square   TC01
Team C Joey  3      Green Triangle TC01
Team D Amy   3      Green Hexagon  TC02
Team E Rose  4      Green Pentagon TC03
Team E Janet 2      Red   Pentagon TC03
