Question

我正在尝试构建一个GUI，该GUI最终将使我们的第二线团队能够轻松地应用查找AD帐户。到目前为止，我仍然无法使用PowerShell来查找在文本框中输入的值，然后评估用户是否存在于AD中。

这是脚本：

Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.Application]::EnableVisualStyles() 

$Form               = New-Object System.Windows.Forms.Form
$Form.ClientSize    = '400,400'
$Form.Text          = "Add DXE Mailbox Permissions"
$Form.TopMost       = $false

$Label1             = New-Object System.Windows.Forms.Label
$Label1.Text        = "Username"
$Label1.AutoSize    = $true
$Label1.Width       = 25
$Label1.Height      = 10
$Label1.Location    = New-Object System.Drawing.Point(15, 145)
$Label1.Font        = 'Microsoft Sans Serif,10'

$TextBox1           = New-Object System.Windows.Forms.TextBox
$TextBox1.Multiline = $false
$TextBox1.Width     = 168
$TextBox1.Height    = 20
$TextBox1.Location  = New-Object System.Drawing.Point(15, 165)
$TextBox1.Font      = 'Microsoft Sans Serif,10'

$Button1            = New-Object System.Windows.Forms.Button
$Button1.Text       = "Check Username"
$Button1.Width      = 120
$Button1.Height     = 30
$Button1.Location   = New-Object System.Drawing.Point(199, 162)
$Button1.Font       = 'Microsoft Sans Serif,10'
$Button1.Add_Click($Button1_Click)

$Form.Controls.AddRange(@($Label1, $TextBox1, $Button1))

$Button1_Click = {
    $username = $Label1.Text
    $Checkuser = Get-ADUser -Identity $username
    if ($Checkuser -eq $null) {
        $Button1.Text = "Can't Find User"
        $button1.ForeColor = "Red"
    } elseif ($Checkuser -ne $null) {
        $Button1.Text = "Found User"
    }
}

[void]$Form.ShowDialog()

我认为我遇到的问题与$username = $Label1.Text行有关。我不确定是否应该将$Label1.Text分配给一个变量，如果可以，我将如何使PowerShell检索已输入的文本？我快速浏览了一下，希望有一种方法可以在不打开和关闭另一个窗口的情况下进行。

Answer 1

您在这里指的是错误的对象

$username = $Label1.text

那是标签。当然，您应该从TextBox中获取值：

$username = $TextBox1.text

Answer 2

您需要在定义之后分配$Button1_Click动作-否则，您只是将$null分配给Click事件：

<# define controls here ... #>
$Form.controls.AddRange(@($Label1,$TextBox1,$Button1))

$Button1_Click = {
  $username = $Label1.text
  $Checkuser = Get-ADUser -Identity $username
  If($Checkuser -eq $null){
    $Button1.Text = "Can't Find User"
    $button1.ForeColor = "Red"
  }
  Elseif($Checkuser -ne $null){
    $Button1.Text = "Found User"
  }
}

$Button1.Add_click($Button1_Click)

[void]$Form.ShowDialog()

如果要从文本框中获取用户名，请将$username = $Label1.text更改为$username = $TextBox1.Text

从数组过滤数组
