【问题描述】：

我是 Powershell 新手，我想编写一个脚本，让最终用户更轻松地将网络打印机添加到他们的系统中。

我想在列表框中列出所有网络打印机，但我没有列出所有打印机名称，而是这样：

这是我的代码

#window
$window = New-Object System.Windows.Forms.Form
$window.Text = 'Select a Printer'
$window.Size = New-Object System.Drawing.Size(500, 400)
$window.StartPosition = 'CenterScreen'

#Button
$okButton = New-Object System.Windows.Forms.Button
$okButton.Location = New-Object System.Drawing.Point(340,130)
$okButton.Size = New-Object System.Drawing.Size(75,23)
$okButton.Text = 'OK'
$okButton.DialogResult = [System.Windows.Forms.DialogResult]::OK
$window.AcceptButton = $okButton

 $cancelButton = New-Object System.Windows.Forms.Button
 $cancelButton.Location = New-Object System.Drawing.Point(340,240)
 $cancelButton.Size = New-Object System.Drawing.Size(75,23)
 $cancelButton.Text = 'Cancel'
 $cancelButton.DialogResult = [System.Windows.Forms.DialogResult]::Cancel
 $window.CancelButton = $cancelButton

 $label = New-Object System.Windows.Forms.Label
 $label.Location = New-Object System.Drawing.Point(10,20)
 $label.Size = New-Object System.Drawing.Size(280,20)
 $label.Text = 'Please select a printer'

 $listBox = New-Object System.Windows.Forms.ListBox
 $listBox.Location = New-Object System.Drawing.Point(10,60)
 $listBox.Size = New-Object System.Drawing.Size(260,20)
 $listBox.Height= 280


 $listBox.Items.Add((Get-Printer -ComputerName srvpr01| select $_.Name))


 $window.Controls.Add($listBox)
 $window.controls.Add($label)
 $window.Controls.Add($cancelButton)
 $window.Controls.Add($okButton)
 $result = $window.ShowDialog()

 if ($result -eq [System.Windows.Forms.DialogResult]::OK)
  
     $x = $listBox.SelectedItem
     $x
  

你知道我可以用什么方法列出打印机名称而不是这个对象吗？ 我感谢每一种帮助和反馈！

【参考方案1】：

您需要使用循环将项目添加到列表框。

改变这一行

$listBox.Items.Add((Get-Printer -ComputerName srvpr01| select $_.Name))

到这里：

Get-Printer -ComputerName srvpr01 | ForEach-Object  $listBox.Items.Add($_.Name)
