Powershell 尝试按嵌套值对对象进行分组
Powershell Attempting to Group object by a nested value
我有一个 json 文件，我正在将其转换为一个名为 $sets 的对象，并且我试图通过嵌套在每个对象中的值对这些对象进行分组。每个对象看起来像这样

有许多与此类似的对象，它们的值不同，但我想根据自定义属性下 account_number 的值对它们进行分组，因为这些是唯一帐户。
根据我阅读其他帖子的理解，您应该能够使用计算出的 属性 来执行此操作，但我终究无法弄清楚该怎么做。
我试过了
$sets | Select-Object Account_Number, @{Name = 'Account_Number'; Expression = { $_ | Select-Object -ExpandProperty CustomAttributes | Where-Object { Name -eq "Account_Number" } | Select-Object -Property Value } } | Group-Object -Property Account_Number
当我尝试时，我收到了消息
The property cannot be processed because the property "Account_Number" already exists.
我相信我对对象分组有相当的把握，因为我可以通过任何 属性 在第一级 IE 中相当容易地做到这一点我可以通过说 BatteryStatus 或 BuildVersion 轻松地做到这一点，但我似乎没有要掌握的是如何从对象的自定义属性中select取正确的值。
我一直在寻找最接近我想做的事情的主要事情是这个条目
试图从提供的答案中收集我自己的答案

给定 CustomAttributes 嵌套对象：
$type Name Value DataType
----- ---- ----- --------
DeviceCustomAttribute Account_Name example account name Text
DeviceCustomAttribute Account_Number 0001 Text
DeviceCustomAttribute example name True Boolean
DeviceCustomAttribute example wave example value Enumerator
并将问题分解成小块，可以得到 Value 属性 的 Value Name 属性 等于 Account_Number 的对象的以下表达式（使用问题中发布的 Json 作为示例):
$json.CustomAttributes.where{ $_.Name -eq 'Account_Number' }.Value # => 0001
从这个意义上说，假设您有一组这些对象作为发布的对象，您可以使用与 Group-Object:
相同的表达式对它们进行分组
$json | Group-Object { $_.CustomAttributes.where{ $_.Name -eq 'Account_Number' }.Value }
例如，我重新创建了 6 个对象并修改了其中一些值，结果是：
Count Name Group
----- ---- -----
4 0001 {@{$type=DeviceIos; ActivationLockBypassCode=example....
1 0002 {@{$type=DeviceIos; ActivationLockBypassCode=example....
1 0003 {@{$type=DeviceIos; ActivationLockBypassCode=example....
