Question

我有一组自定义对象，并且需要对每个对象执行以下步骤：

将“ Team1组”替换为“ Team2组”
将结果更新保存到哈希表中，然后将其传递给API

对象看起来像这样：

id             : 1
groupId        : 1
name           : Customer1 Dashboard
fullName       : Customer Dashboards/Team2 Group/Customer1 Group/Customer1 Dashboard
groupName      : Customer1 Group
groupFullPath  : Customer Dashboards/Team2 Group/Customer1 Group
widgetTokens   : { @{type = owned; name = defaultResourceGroup; value = Client Teams/Team1 Group/Customers/Customer1*; inheritList = System.Object[] }, @{type = owned; name = defaultWebsiteGroup; value = Client Teams/Team1 Group/Customers/Customer1; inheritList = System.Object[]}}

这是我到目前为止所拥有的：

Foreach ($dashboard in $allDashboards) {
    $dashboardProperties = @{ }
    $dashboard.psobject.properties | ForEach-Object {         $dashboardProperties[$_.Name] = $_.Value }
@($dashboardProperties.GetEnumerator()) | Where-Object { $_.Name -eq 'widgetTokens' } | Select-Object -ExpandProperty Value | Where-Object { $_.Value -match "Team1 Group" } | ForEach-Object { $dashboardProperties[$_.Key] = @($_.value.replace('Team1 Group', 'Team2 Group')) }
$dashboardProperties
#Code to interact with an API

}

因为有两个项目与“ @（$ dashboardProperties.GetEnumerator（））| Where-Object {$ _。Name -eq'widgetTokens'} ...”行匹配（至少，我认为这是原因），出现以下错误：

Index operation failed; the array index evaluated to null.
At line:1 char:200
+ ... ch-Object { $dashboardProperties[$_.Key] = @($_.value.replace('Team1 ...
    +                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : NullArrayIndex

    Index operation failed; the array index evaluated to null.
    At line:1 char:200
    + ... ch-Object { $dashboardProperties[$_.Key] = @($_.value.replace('Team1 ...
+                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : NullArrayIndex

运行此命令时，我看到了两行，如预期的那样：

@($dashboardProperties.GetEnumerator()) | Where-Object { $_.Name -eq 'widgetTokens' } | Select-Object -ExpandProperty Value | Where-Object { $_.Value -match "Team1 Group" }

有什么想法，我不确定该如何克服？

谢谢

根据Reddit的反馈，看起来应该可以：

$DashboardProperties.WidgetTokens |
Where-Object { $_['Name'] -eq 'widgetTokens' -and $_['Value'] -match 'Team1 Group' } |
ForEach-Object { $_['Value'] = $_['Value'] -replace '1','2' }
