所以我有一个名为 $monitors 的数组。我认为它包含的内容并不重要，但它是一个 SCOM 监视器列表，由以下两行创建：
Start-OperationsManagerClientShell -ManagementServerName: "your-mgmt-server" -PersistConnection: $false -Interactive: $false;
$monitors = Get-SCOMMonitor | Where-Object -Property XmlTag -eq "UnitMonitor"
输出这个数组，它的成员似乎有两个属性，称为 Overridden 和 Target（一直向右滚动）：
PS D:\Daniel> $monitors
Enabled DisplayName ParentMonitorID Overri Target

但根据Get-Member，“覆盖”不存在：

Target 属性确实存在，但如果我尝试使用以下方式打印它，它的值会完全不同Format-Table：
PS D:\Daniel> $monitors | Format-Table Target
Target
------
ManagementPackElementUniqueIdentifier=e817d034-02e8-294c-3509-01ca25481689
ManagementPackElementUniqueIdentifier=0302db52-58b0-43ff-65fe-0b492a1461ae
ManagementPackElementUniqueIdentifier=979b9385-5195-5be8-ce28-1467a6323c36
ManagementPackElementUniqueIdentifier=2d34f1de-ce5d-9a5d-bce1-67b75619d3a6
扩展属性仍然没有显示我们之前看到的值：
PS D:\Daniel> $monitors | Select-Object -ExpandProperty Target | Format-List *

如何访问 Target 和 Overridden 参数，以便对它们进行排序、将它们导出为 CSV 等？
