Exception Powershell WMIOObject异常处理

我很难捕获一些管理异常和ComException。这是我得到的两个错误代码，System.UnauthorizedAccessException似乎工作正常。

获取WmiObject:
在C:\Scripts\Exception\u CheckDiskSpace.ps1:141 char:26
+$disks=Get WmiObject根据Frode F.的上述评论向Get WmiObject添加-ErrorAction Stop有效。
您是否尝试将
-ErrorAction Stop
添加到您的
Get WmiObject
命令中？您太棒了，尽管我不知道为什么哈哈。谢谢
ErrorAction
参数定义cmdlet（
Get WmiObject
）将如何对错误做出反应。通常，它会给您一个错误，但仍然会继续执行脚本，除非错误是终止（致命）错误。通过将属性设置为
Stop
，您可以告诉它在每次发生错误时抛出异常。
