如何选择对象＆＃34;在多个多值属性？

我试图检索Google日历事件并将它们批量复制到SQL Server表中。

$requestUri = "https://www.googleapis.com/calendar/v3/calendars/.../events"
$calEvents = Invoke-RestMethod -Headers @{Authorization = "Bearer $accessToken"} -Uri $requestUri -Method Get -Body $Parameters -ContentType "application/json; charset=utf-8"
$dt = $calEvents.items | Select-Object id, ????????? | Out-DataTable
...
$bulkCopy.WriteToServer($dt)

所以我的问题是要投入什么？所以我可以将组织者 - 电子邮件，创建者 - 电子邮件，开始日期，结束日期保存到表格中。

$calEvents.items看起来像这样：

created     : 2017-08-28T07:18:19.000Z
updated     : 2017-08-29T16:41:00.441Z
summary     : Vacation
creator     : @{email=XXX@YYY.com; displayName=XXX}
organizer   : @{email=XXX@YYY.com}
start       : @{date=2018-03-26}
end         : @{date=2018-03-31}
...

所以我想只从@{}多值中检索电子邮件和日期元素。 知道怎么样？ （我知道我只能扩展一个属性）。

这些很可能是嵌套对象。你应该能够“平坦化”＃34;您的数据使用calculated properties：

$dt = $calEvents.items |
      Select-Object id, @{n='creator';e={$_.creator.email}},
          @{n='organizer';e={$_.organizer.email}},
          @{n='start';e={$_.start.date}},
          @{n='end';e={$_.end.date}} |
      Out-DataTable
