.NET DateTimePicker 日历未出现在 PowerShell 表单中

Question

我试图在 PowerShell 的 WinForms 表单中显示 DateTimePicker。出现表单时，可以更改日期，但点击下拉按钮不会显示日历。好像有什么事情发生了，只是看不见而已。

我在这里错过了什么愚蠢的东西？

$form = New-Object Windows.Forms.Form
$form.Size = New-Object Drawing.Size @(400, 400)
$form.StartPosition = "CenterScreen"
$form.Text = "When do you want the snapshot to be taken?"
$form.Font = New-Object Drawing.Font("Microsoft Sans Serif",12)
$form.FormBorderStyle = [Windows.Forms.FormBorderStyle]::Fixed3D

$panel = New-Object Windows.Forms.FlowLayoutPanel
$panel.Height = 400
$panel.Width = 400
$panel.AutoScroll = $true
$panel.FlowDirection = [Windows.Forms.FlowDirection]::TopDown
$panel.WrapContents = $false

$titleText = New-Object Windows.Forms.Label
$titleText.AutoSize = $true
$titleText.Text = "When do you want the snapshot to be taken?"
$panel.Controls.Add($titleText)

$datePicker = New-Object Windows.Forms.DateTimePicker
$datePicker.ShowUpDown = $false
$datePicker.MinDate = $now
$datePicker.MaxDate = $now.AddMonths(3); #arbitrary
$datePicker.MaxSelectionCount = 1
$datePicker.Width = 350
$datePicker.Enabled = $false
$panel.Controls.Add($datePicker)

$form.Controls.Add($panel)
$drc = $form.ShowDialog()

你的代码似乎在我的电脑上运行良好。我复制粘贴了您的代码并将 Add-Type 添加到顶部：

Add-Type -AssemblyName System.Windows.Forms

并更改了 $datePicker.Enabled:

$datePicker.Enabled = $true

当运行时，我可以更改 date/time 并且下拉列表也按预期工作：
