Powershell foreach + 获取

我是 powershell 的新手，需要你的帮助解决这个问题。

我需要Get-PrinterConfiguration和Get-Printer大家共同努力。

我找到了这个代码：

$Printers = Get-Printer *
Foreach ($Printer in $Printers){Get-PrintConfiguration -PrinterName $Printer.name}

但我仍然需要一些信息Get-Printer，但我不知道如何使它们协同工作。

例如我需要：

Name，，，，来自 和 ，来自。DriverName​PortName​​CommentLocationGet-PrinterColorDuplexingModeGet-PrintConfiguration

你们能帮助我吗？

这...

$Printers = Get-Printer *
Foreach ($Printer in $Printers){Get-PrintConfiguration -PrinterName $Printer.name}

...可以简化为这样...

Get-Printer | 
Foreach {Get-PrintConfiguration -PrinterName $PSItem.name}

在开始之前使用帮助文件了解哪些是可用的/哪些是不可用的

您需要选择所需的内容，然后使用哈希表或自定义对象将它们组合在一起。现在这不是第一天的事情，但同样，关于组合 cmdlet 输出的文章/博客/视频、样本/示例非常丰富。

PowerShell 组合 cmdlet 输出

例子：

Get-Printer | 
Select-Object -First 1 | 
Select-Object -Property Name, DriverName, PortName, Comment, Location, 
@{
    Name       = 'Color'
    Expression = {(Get-PrintConfiguration -PrinterName $PSItem.Name).Color}
},
@{
    Name       = 'DuplexingMode '
    Expression = {(Get-PrintConfiguration -PrinterName $PSItem.Name).DuplexingMode }
}
# Results

要获取所有打印机，请删除此行...

Select-Object -First 1 |

...您的用例不需要 ForLoop。

如果想压缩行数，上面也可以这样写。

Get-Printer | Select-Object -Property Name, DriverName, PortName, Comment, Location, 
@{Name = 'Color';Expression = {(Get-PrintConfiguration -PrinterName $PSItem.Name).Color}},
@{Name = 'DuplexingMode';Expression = {(Get-PrintConfiguration -PrinterName $PSItem.Name).DuplexingMode}}
# Results

然而，我发现这更难阅读。但这只是我个人的看法。使用自然换行符（如 '|'、';'、::'、比较运算符等）可以使内容更易于阅读。

以下脚本演示了如何从多个类中获取属性并将它们全部统一到一个新对象中。

我让你学习和理解所使用的命令并根据您的需要调整脚本。

$Printers = Get-Printer *
Foreach ($Printer in $Printers){
$x = new-object -typename psobject 
$x | Add-Member -Type NoteProperty -Name PrinterName -Value $Printer.name
$x | Add-Member -Type NoteProperty -Name DriverName -Value $Printer.DriverName
$x | Add-Member -Type NoteProperty -Name PortName -Value $Printer.PortName
$x | Add-Member -Type NoteProperty -Name Comment -Value $Printer.Comment
$x | Add-Member -Type NoteProperty -Name Location -Value $Printer.Location
$config = Get-PrintConfiguration -PrinterName $Printer.name
$x | Add-Member -Type NoteProperty -Name Color -Value $config.Color
$x | Add-Member -Type NoteProperty -Name DuplexingMode -Value $config.DuplexingMode
Write-Output $x
}
