Question

我想创建一个词典列表，以便我将其导出为CSV。正如您在PowerShell中可能知道的那样，如果要将填充了字符串的数组导出到CSV文件，它就无法工作，所以我必须为此创建对象。

但是如果我回避这种方式就行了，而且我觉得这不是创建词典/哈希表列表的正确方法，但我并没有创造一个重复代码的功能（对不起）。

#add the log file.
$savegrp = Get-Content "J:\savegrp.dec.2015.log"
#filtering into a var just Succeeded/Failed data then replace  space with ';' and remove ','
$succeded = ($savegrp -cmatch "Succeeded:") -replace "\s+",";" -replace ",",""
$failed = ($savegrp -cmatch " Failed: ") -replace "\s+",";" -replace ",",""

#creating container where all data will be added
$container = @()
#just a date to save the csv file if this script will be scheduled 
$date =  Get-Date -format dd.MMMM.yyyy

#take each line of data with 'Succeeded' match and iterate it
for($i=0;$i -le ($succeded.count-1);$i++) {

    #split each line by ';' to see how many items are per one line
    $s1 = ($succeded[$i]).split(";")

    #if in one 'Succeeded' line are just 6 element then is just one server which is ok
    if ($s1.count -eq 6){

        $PropertyHash = @{}
        $PropertyHash =  @{
            "Date" = $s1[1] + " " + $s1[0]
            "Time" = $s1[2]
            "Client" = $s1[5]
            "Status" = $s1[4].Substring(0,9)
        }
        $container += New-Object -TypeName PSObject -Property $PropertyHash
    }
    #if in one 'Succeeded' line are more servers, then stick all sererers to the same info in the line
    else{
        $count = ($s1.count)

        for($a = $count-1;$a -ge 5){

            $PropertyHash = @{}
            $PropertyHash +=  @{
                "Date" = $s1[1] + " " + $s1[0]
                "Time" = $s1[2]
                "Client" = $s1[$a]
                "Status" = $s1[4].Substring(0,9)
            }
            $container += New-Object -TypeName PSObject -Property $PropertyHash
            $a--
        }
    }
}

如果你有PowerShell v3或更新版本，这样的东西应该可以正常工作：

for ($i = 0; $i -lt $succeded.Count; $i++) {
  $date1, $date2, $time, $null, $status, $clients = $succeded[$i].Split(';')
  $clients | ForEach-Object {
    New-Object -Type PSObject -Property @{
      'Date'   = "$date2 $date1"
      'Time'   = $time
      'Client' = $_
      'Status' = $status.Substring(0,9)
    }
  } | Export-Csv 'C:\path\to\output.csv' -NoType -Append
}

PowerShell允许您将数组分配给变量列表，每个变量都从数组中获取一个元素，最后一个元素除外，它接受所有剩余的数组元素。声明

$date1, $date2, $time, $null, $status, $clients = $succeded[$i].Split(';')

在相应变量$date1，$date2，$time和$status中收集日期，时间和状态。将第4个值分配给$null，将其丢弃。分割操作产生的数组的其余部分（客户端列表）被分配给＆＃34; catch-all＆＃34;变量$clients。然后，您可以将该变量传递到ForEach-Object语句，在该语句中为每个客户端创建一个对象，并将它们附加到CSV文件中（请注意，至少需要PowerShell v3才能附加到CSV）。

修改：如果您遇到PowerShell v2或更早版本，您也可以在循环外进行导出。但是，要实现这一点，您需要在子表达式中运行它：

(for ($i = 0; $i -lt $succeded.Count; $i++) {
  $date1, $date2, $time, $null, $status, $clients = $succeded[$i].Split(';')
  $clients | ForEach-Object {
    New-Object -Type PSObject -Property @{
      'Date'   = "$date2 $date1"
      'Time'   = $time
      'Client' = $_
      'Status' = $status.Substring(0,9)
    }
  }
}) | Export-Csv 'C:\path\to\output.csv' -NoType

或首先在变量中收集结果：

$container = for ($i = 0; $i -lt $succeded.Count; $i++) {
  $date1, $date2, $time, $null, $status, $clients = $succeded[$i].Split(';')
  $clients | ForEach-Object {
    New-Object -Type PSObject -Property @{
      'Date'   = "$date2 $date1"
      'Time'   = $time
      'Client' = $_
      'Status' = $status.Substring(0,9)
    }
  }
}

$container | Export-Csv 'C:\path\to\output.csv' -NoType
