解析多字段CSV文件

我有一个CSV文件，看起来像这样

WRK-STATION-1, Room 54 WRK-STATION-2, Room 12 WRK-STATION-3, Room 45 WRK-STATION-4, Room 11 WRK-STATION-5, Room 32 我想弄清楚如何让它理解有两列。

使用而不是

获取内容

。如果输入文件没有标题行，可以通过

-header

参数指定列标题

$computerlist = Import-Csv $COMPUTERLIST -Header Name,Room -ErrorAction Stop

这样，您可以像这样使用它：

$computerlist = Get-Content $COMPUTERLIST -ErrorAction Stop
foreach ($computer in $computerlist) {
    if ((Test-Connection -ComputerName $computer -Quiet) -eq $true) {
        # some stuff happens here
        # I would like to Output to the screen "The computer with tha name
        # WRK-STATION-1 in Room 54 has been completed"
        # Or create an output file that adds a 3rd column to my input saying
        # "COMPLETED"
    } else {
        # I would like to Output to the screen "The computer with tha name
        # WRK-STATION-1 in Room 54 has failed"
        # Or create an output file that adds a 3rd column to my input saying
        # "FAILED"
    }

foreach ($computer in $computerlist) {
    if (Test-Connection -ComputerName $computer.Name -Quiet) {
        ...
    } else {
        "Computer $($computer.Name) in $($computer.Room) has failed."
    }
}

也许，你需要这样的东西

  $computerlist = Get-Content $COMPUTERLIST -ErrorAction Stop
  foreach ($computerInfo in $computerlist) {
       $computer = $computerInfo -split ',' | select -First 1
       if((Test-Connection -ComputerName $computer -Quiet) -eq $true) {
         # some stuff happens here
         # I would like to Output to the screen "The computer with tha name WRK-STATION-1 in Room 54 has been completed"
         # Or create an output file that adds a 3rd column to my input saying "COMPLETED"
       }
       else {
         # I would like to Output to the screen "The computer with tha name WRK-STATION-1 in Room 54 has failed"
         # Or create an output file that adds a 3rd column to my input saying "FAILED"
   }

谢谢，但我如何访问第二个字段？因为foreach（$computerlist中的computer）{将被破坏，因为答案中有2个字段而不是1。您通过说出$computer.name访问第一个字段，然后通过说出$computer.room访问第二个字段。名称“name”和“room”是任意选择，在import csv语句的-header子句中声明。我在我的csv文件中创建了一个标题，并使用了与您相同的语法。它使用标题作为我的测试连接的第一行。是否要跳过它？请再次阅读：如果输入文件没有标题行，您可以通过

-Head指定列标题er
