Question

下面是我用来检查不同文件夹的代码的简化版本，检查最新的日志文件，然后报告最近的3个时间戳（用[表示）。

$LogLocations = "C:\Powershell\Test\Scenario1",
                "C:\Powershell\Test\Scenario2"

$style = @"
<style>BODY{font-family: Arial; font-size: 10pt;}
TABLE{border: 1px solid black; border-collapse: collapse;}
TH{border: 1px solid black; background: #dddddd; padding: 5px; }
TD{border: 1px solid black; padding: 5px; }
</style>
"@

$body = ""

foreach ($logpath in $LogLocations) {
    $log  = Get-ChildItem -Path $logpath |
            sort LastWriteTime |
            select -ExpandProperty FullName -Last 1
    $text = Get-Content -Path $log |
            Select-String -SimpleMatch "[" |
            select Line -Last 3
    $body += ($text |
             select Line |
             ConvertTo-Html -Body "<p>Timestamps of 3 most recent files processed $log</p>" -Head $style |
             Out-String)
}

$emailbody = ConvertTo-Html -PostContent $body | Out-String
$subject = "Processing Logs Error Checking at " + (Get-Date -Format g)

Send-MailMessage -From "xxxxxxxxx" -To "xxxxxxxxx" -Subject $subject -Body $emailbody -BodyAsHtml -SmtpServer "xxxxxxxxx"

我得到的结果是：

Timestamps of 3 most recent files processed C:\Powershell\Test\Scenario1\20160520163102.txt
*
[05/21/2016 00:37:52]
[05/21/2016 00:37:52]
[05/21/2016 00:37:52]
Timestamps of 3 most recent files processed C:\Powershell\Test\Scenario2\20160524142045.txt
*
[05/24/2016 14:38:48]
[05/24/2016 14:38:51]
[05/24/2016 14:38:51]

哪个好。我得到了我想要的信息，只是格式不是最好的。我试图找到一种方法将结果放在同一个表中，但是无法使代码生效，我会得到错误，没有结果或者格式化结果非常糟糕。

有什么想法吗？我正在将当前foreach语句嵌套在表列的另一个foreach语句中。

如果您不想要多个表格，请不要创建多个表格。

$emailbody = $LogLocations | ForEach-Object {
    $dir = $_
    Get-ChildItem $dir |
        Sort-Object LastWriteTime |
        Select-Object -Last 1 |
        Get-Content |
        Where-Object { $_ -like '*[*' } |
        Select-Object -Last 3 @{n='File';e={$dir.FullName}},
            @{n='Timestamp';e={$_}}
} | ConvertTo-Html -Head $style

ForEach循环导致单个HTML表
