(Powershell) 捕获“Get-WinEvent：未找到事件”Get-WinEvent答案

【问题标题】：(Powershell) Catch "Get-WinEvent : No events were found" Get-WinEvent(Powershell) 捕获“Get-WinEvent：未找到事件”Get-WinEvent
【发布时间】：2014-10-31 17:12:00
【问题描述】：

当我运行以下命令按 ID 列出日志时，它显示 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“未找到事件”。

我运行的命令-

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

我在下面尝试过，但无法正常工作-

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";
                 }
    }

请帮忙。谢谢

【解决方案1】：

这是一个非终止错误，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";
                 }
    }
