(Powershell)捕获"Get-WinEvent :找不到任何事件“Get-WinEvent

Question

当我运行下面的命令按ID列出日志时，它显示为Get-WinEvent : No events were found that match the specified selection criteria.

如何捕获此异常并显示一条简单的消息“找不到事件”。

我运行的命令-

Get-WinEvent -FilterHashtable @{LogName="Application";ID="191"}

我在下面试过了，但不能让它工作-

try { Get-WinEvent -FilterHashtable @{LogName="Application";ID="191"}
    }

catch [Exception] {
        if ($_.Exception -match "No events were found that match the specified selection criteria") {
        Write-Host "No events found";
                 }
    }

请帮帮忙。谢谢

这是一个非终止性错误，不会被try/catch捕获。使用-ErrorAction Stop。

try { Get-WinEvent -FilterHashtable @{LogName="Application";ID="191"} -ErrorAction Stop
    }

catch [Exception] {
        if ($_.Exception -match "No events were found that match the specified selection criteria") {
        Write-Host "No events found";
                 }
    }
