Question

因此，我有一个解析器，该解析器遍历两个不同的日志（两个.csv文件），并根据我选择的正则表达式代码检查某些行。

此文件从文件名的开头（1234-randomfile.csv）抓取IDNumber，然后将文件位置添加到变量（$ Validate），然后基于正则表达式，将文件添加到某些变量（$ Scriptdone， $ Updatedone，$ Failed），然后开始检查以查看它们是否具有它们。

我正在尝试使其成为一行一行，因为我解析的文件具有相同的IDNumbers。例如：

当前输出：

1234 Script Completed
1234 Update Completed

我要如何输出：

1234 Script Completed Update Completed

无论如何，谢谢您的协助！

如果要将新消息追加到现有输出，则必须告诉PowerShell应该将新信息添加到哪个条目。由于我认为操作字符串不是很直观，因此建议您使用一个对象。

首先，您必须定义数据结构：

// Before ForEach
$array = @()
$properties = @{'ID'="";
            'Results'=""}
// In ForEach
$object = New-Object –TypeName PSObject –Prop $properties
$object.ID = $IDNumber

接下来，在您的if中，您可以设置值（也可以按照@LotPings的建议使用Switch进行设置，但为了简单起见，请将其保留不变）：

$object.Results = $Done // or $Fail or $Fail2

然后，您应该首先检查带有$ID的条目是否已经存在，如果是，则添加新结果。如果否，则只需将新元素添加到数组中。这样的事情应该起作用：

$line = $array | Where-Object ID -eq $object.id
if ($line) {
  $line.Results += " $($object.Results)"
}
else {
  $array += $object
}

当然，这还需要更改数据输出方式（例如，使用Export-Csv）：

$array | Export-Csv $CSVPath -Append -NoTypeInformation
