【问题描述】：

我有一组用于团队名称和电子邮件的对象，以及与该团队相关联的票在一个单独的数组中，但是它并没有像预期的那样工作，我已经被这个难住了一段时间......

代码：

$teamConfig = @(
    [pscustomobject]@{
        TeamName='Team1';
    }
)

$query = "select * from INCAutomation"

$results = Invoke-Sqlcmd -query $query -ServerInstance 'localhost' -Database 'AyushTest'

$collectionWithItems = @()
$array = @()

foreach ($i in $results) {
    foreach ($x in $teamConfig) {
        if ($i.TeamName -eq $x.TeamName) {
            $array += $i.TicketID

            $temp = New-Object System.Object
            $temp | Add-Member -MemberType NoteProperty -Name "TeamName" -Value $i.TeamName
            $temp | Add-Member -MemberType NoteProperty -Name "TeamEmail" -Value $i.TeamEmail
            $temp | Add-Member -MemberType NoteProperty -Name "TicketID" -Value $array
            $collectionWithItems += $temp
        }
    }
}

$collectionWithItems = $collectionWithItems | select 'TeamName', 'TeamEmail', 'TicketID' -Unique

$collectionWithItems

输出：

TeamName TeamEmail      TicketID
-------- ---------      --------
Team1    Team1@test.com {INC0001}
Team1    Team1@test.com {INC0001, INC0002}
Team1    Team1@test.com {INC0001, INC0002, INC0003}
Team1    Team1@test.com {INC0001, INC0002, INC0003, INC0004}

期望的输出：

TeamName TeamEmail      TicketID
-------- ---------      --------
Team1    Team1@test.com {INC0001, INC0002, INC0003, INC0004}

我也感到困惑的另一件事是，这需要与多个团队合作，例如：

$teamConfig = @(
    [pscustomobject]@{
        TeamName='Team1';
    }
    [pscustomobject]@{
        TeamName='Team2';
    }
    [pscustomobject]@{
        TeamName='Team3';
    }
)

因此，所需的输出应该是：

TeamName TeamEmail      TicketID
-------- ---------      --------
Team1    Team1@test.com {INC0001, INC0002, INC0003, INC0004}
Team2    Team2@test.com {INC0005, INC0006, INC0007, INC0008}
Team3    Team3@test.com {INC0009, INC0010, INC0011, INC0012}

提前致谢！

【解决方案1】：

您的外部循环应该遍历$teamConfig，这样您就只需要遍历每个团队一次。

要获取与当前团队名称关联的票，您可以使用Where-Object，如下所示：

$ticketIds = $results |Where-Object TeamName -eq $team.TeamName |Select -ExpandProperty TicketID

让你大大简化你的代码：

$teamConfig = @(
    [pscustomobject]@{
        TeamName  = 'Team1'
        TeamEmail = 'team1@domain.tld'
    }
    [pscustomobject]@{
        TeamName  = 'Team2'
        TeamEmail = 'team2@domain.tld'
    }
    [pscustomobject]@{
        TeamName  = 'Team3'
        TeamEmail = 'team3@domain.tld'
    }
)

$query = "select * from INCAutomation"

$results = Invoke-Sqlcmd -query $query -ServerInstance 'localhost' -Database 'AyushTest'

$teamTickets = foreach($team in $teamConfig){
  # Filter tickets based on team name
  $ticketIds = $results |Where-Object TeamName -eq $team.TeamName |Select -ExpandProperty TicketID

  # Output a single object per team, with all ticket IDs attached
  $team |Select TeamName,TeamEmail,@{Name='TicketID';Expression={ $ticketIds }}
}

$teamTickets 现在在$teamConfig 中每个团队只包含一个对象。
