powershell - 变量中具有多个ID的Get-WinEvent -FilterHashTable不起作用

Question

这项工作对我来说:

Get-WinEvent -FilterHashTable @{Logname = "ForwardedEvents" ; ID = 4625,4740}

(...我期望的结果...)

这有效:

$EventId = "4625"

Get-WinEvent -FilterHashTable @{Logname = "ForwardedEvents" ; ID = $EventId}

这不起作用:

$EventId = "4625,4740"

Get-WinEvent -FilterHashTable @{Logname = "ForwardedEvents" ; ID = $EventId}

错误...

  Get-WinEvent : No events were found that match the specified selection criteria.
At line:1 char:13
+ Get-WinEvent <<<<  -FilterHashTable @{Logname = "ForwardedEvents" ; ID = $EventIds}
+ CategoryInfo          : ObjectNotFound: (:) [Get-WinEvent], Exception
+ FullyQualifiedErrorId : NoMatchingEventsFound,Microsoft.PowerShell.Commands.GetWinEventCommand

有人可以帮忙吗？

Answer 1

在您的示例中，使用多个ID，您正在做两种不同的事情。
$EventId = "4625,4740"定义一个字符串。您的工作示例使用一个定义为逗号分隔数字的整数数组。

只需将其更改为$EventId = 4625,4740(去掉引号)即可。查看documentation for Get-WinEvent and the -FilterHashTable ，我们看到:

-- ID=<Int32[]>

因此，它期望一个数组而不是一个字符串。
