将 PSCustom 对象添加到数组

Question

我正在使用双 for 循环来列出所有团队的频道及其类型，以便将它们导出为 CSV：

$TeamsPool = Get-Team | Select DisplayName,GroupID # Existing Teams
$Report = @() # Final Report

foreach($team in $TeamsPool)
{
    $TeamsChannel = @{} | Select Teams,Channel,Type
    $TeamsChannel.Teams = $team.DisplayName
    $teamschannels = Get-TeamChannel -GroupId $team.GroupID
    foreach($Channel in $teamschannels)
    {
        $TeamsChannel.Channel=$Channel.DisplayName
        $TeamsChannel.Type=$Channel.MembershipType
        $Report+=$TeamsChannel
    }
}

该代码在具有单个通道的 Teams 上运行良好，但一旦有多个通道，该 Teams 的“$Report”中的所有值都会被最后一个值替换：

预期结果：

Teams	Channel	Type
Teams 1	General	Public
Teams 1	Public Channel 1	Public
Teams 2	General	Public
Teams 2	Public Channel 2	Public
Teams 2	Private Channel 2	Private

实际结果：

Teams	Channel	Type
Teams 1	Public Channel 1	Public
Teams 1	Public Channel 1	Public
Teams 2	Private Channel 2	Private
Teams 2	Private Channel 2	Private
Teams 2	Private Channel 2	Private

将 PSCustomObject 添加到 Arrays 时似乎有一个特殊的交互，但我一直无法找出是哪个。

您目前正在为每个团队创建一个输出对象，而不是每个频道 - 所以您最终会覆盖点击最后一个频道时的前一个输出对象。

将您的代码更改为：

$TeamsPool = Get-Team | Select DisplayName,GroupID # Existing Teams
$Report = @() # Final Report

foreach($team in $TeamsPool)
{
    $teamschannels = Get-TeamChannel -GroupId $team.GroupID
    foreach($Channel in $teamschannels)
    {
        # Create new object per-channel
        $TeamsChannel = @{} | Select Teams,Channel,Type

        $TeamsChannel.Teams = $team.DisplayName
        $TeamsChannel.Channel=$Channel.DisplayName
        $TeamsChannel.Type=$Channel.MembershipType

        $Report += $TeamsChannel
    }
}

我个人的偏好是使用 [pscustomobject] 而不是 select，并将整个循环表达式分配给 $Report 而不是 +=:

$TeamsPool = Get-Team | Select DisplayName,GroupID # Existing Teams

$Report = foreach($team in $TeamsPool)
{
    $teamschannels = Get-TeamChannel -GroupId $team.GroupID
    foreach($Channel in $teamschannels)
    {
        # Create new object per-channel
        [pscustomobject]@{
            Teams = $team.DisplayName
            Channel = $Channel.DisplayName
            Type = $Channel.MembershipType
        }
    }
}
