Powershell-获取任务计划程序运行结果的历史记录

我有一个Powershell脚本,如下所示:

if (something)
{
    # do something
    # will return 0 on success
}
else
{
    exit 12345
}

我希望能够检查在过去24小时内是否至少有一次成功(返回代码0)(脚本将返回大于0的12345)。

在另一个脚本中,我有以下代码:

$events = @(
     Get-WinEvent  -FilterXml @'
     <QueryList>
      <Query Id="0" Path="Microsoft-Windows-TaskScheduler/Operational">
       <Select Path="Microsoft-Windows-TaskScheduler/Operational">
        *[EventData/Data[@Name='taskname']='\My Test']
       </Select>
      </Query>
     </QueryList>
'@  -ErrorAction Stop


$events | Where-Object {$_.ID -eq 102} | Select-Object *

它向我显示了任务运行的历史记录,但我无法从这里找到如何获得运行结果。

我可以按如下方式询问单个历史项目:

$a = $events | Where-Object {$_.ID -eq 102} | Select-Object *
$a[0] | Get-Member

返回

但是,我在任何一处房产中都找不到我需要的信息。我希望它以十六进制格式存储在某个地方 (0x3039) .
