Question

我正在尝试创建Powershell脚本，该脚本将搜索指定的文件夹并将所有子文件夹列出到列表框中。当用户从列表框中选择文件夹时，将执行操作。

我对Powershell还是很陌生，所以我不知道我是否走在正确的轨道上，但是我尝试将目录放入数组中，我只是不知道如何将数组放入列表框中。

$items = Get-ChildItem -Path $path


foreach ($item in $items)

{

  # if the item is a directory, then process it.

  if ($item.Attributes -eq "Directory")

  {

        Write-Host $item.Name

  }

}

Answer 1

对于演示，这是一个简单的表单，其中用子文件夹路径填充列表框。

$rootFolder = 'PATH TO YOUR ROOTFOLDER HERE'

# get an array of subfolder full names in the $rootFolder
$subfolders = (Get-ChildItem -Path $rootFolder -Recurse -Directory).FullName

Add-Type -AssemblyName System.Windows.Forms
$form = New-Object System.Windows.Forms.Form 
$form.Text = "SubFolders"
$form.Size = New-Object System.Drawing.Size(300,300) 
$form.StartPosition = "CenterScreen"

$listBox = New-Object System.Windows.Forms.ListBox
$listBox.Location = New-Object System.Drawing.Point(10,40) 
$listBox.Size = New-Object System.Drawing.Size(260,180)
$listBox.Anchor = 'Top,Right,Bottom,Left' 

# fill the listbox with subfolder names
$listBox.items.AddRange($subfolders)

# add an event handler on the listbox to do something with the selected item
$listBox.Add_Click({
    # here put your code to perform some action with the selected subfolder
    $selected = $listBox.GetItemText($listBox.SelectedItem)
    # for demo, simply show a messagebox
    [System.Windows.Forms.MessageBox]::Show("You selected subfolder`r`n`r`n$selected", "Subfolder")
})

$form.Controls.Add($listBox) 

$form.ShowDialog()
$form.Dispose()

更新

根据您的评论，您想在显示LastWriteTime（lastModified）日期的列表框中添加第二列。

可以很容易地改编早期代码，以添加字符串项，这些字符串项是文件夹FullNames的组合，并使用某种分隔字符将其与LastWriteTime组合在一起。稍后，将所选字符拆分到该字符上，以仅获取文件夹名称。

但是，就用户体验而言，这会使整个事情变得一团糟。.
添加新列会更好，但是尽管Listbox对象确实具有MultiColumn属性，但使用它的结果很可能不您期望的结果。

在下面的更新的代码中使用了ListView对象而不是ListBox对象中的多个列。

$rootFolder = 'PATH TO YOUR ROOTFOLDER HERE'

# get an array of subfolder objects in the $rootFolder
$subfolders = Get-ChildItem -Path $rootFolder -Recurse -Directory

Add-Type -AssemblyName System.Windows.Forms
$form = New-Object System.Windows.Forms.Form 
$form.Text = "SubFolders"
$form.Size = New-Object System.Drawing.Size(600,400) 
$form.StartPosition = "CenterScreen"

$listView = New-Object System.Windows.Forms.ListView
$listView.Location = New-Object System.Drawing.Point(10,40) 
$listView.Size = New-Object System.Drawing.Size(560,280) 
$listView.Anchor = 'Top,Right,Bottom,Left'
$listView.View = 'Details'
$listView.FullRowSelect = $true
$listView.GridLines = $true

[void]$listView.Columns.Add("Folder", 338);
[void]$listView.Columns.Add("LastModified", 200);
# fill the listbox with subfolder names and Last Modified dates
$subfolders | ForEach-Object {
    $row = New-Object System.Windows.Forms.ListViewItem( $_.FullName)  # the folder path goes into the first column
    [void]$row.SubItems.Add($_.LastWriteTime.Tostring())               # the LastWriteTime goes into the second column
    [void]$listView.Items.Add($row)
}

# add an event handler on the listbox to do something with the selected item
$listView.Add_Click({
    # here put your code to perform some action with the selected subfolder
    $selected = $listView.SelectedItems[0].Text
    # for demo, simply show a messagebox
    [System.Windows.Forms.MessageBox]::Show("You selected subfolder`r`n`r`n$selected", "Subfolder")
})

$form.Controls.Add($listView) 

[void]$form.ShowDialog()
$form.Dispose()
