Powershell UI - DialogResult - PropertyAssignmentException

Question

我正在为某些脚本创建一个powershell UI。

现在我跑错了。但首先，这是我的表格代码：

$form_appBase = New-Object System.Windows.Forms.Form
        $form_appBase.Text = 'APP Policy creator'
        $form_appBase.Width = 350
        $form_appBase.Height = 150
        $form_appBase.AutoSize = $true

        $label_appFilename = New-Object System.Windows.Forms.Label
        $label_appFilename.Location = '10,10'
        $label_appFilename.Size = '200,15'
        $label_appFilename.Text = 'Program'

        $Textbox_appFilename = New-Object System.Windows.Forms.TextBox
        $Textbox_appFilename.Location = '10,30'
        $Textbox_appFilename.Size = '200,25'

        $label_appVersion = New-Object System.Windows.Forms.Label
        $label_appVersion.Location = '220,10'
        $label_appVersion.Size = '100,15'
        $label_appVersion.Text = 'Version:'

        $Textbox_appVersion = New-Object System.Windows.Forms.TextBox
        $Textbox_appVersion.Location = '220,30'
        $Textbox_appVersion.Size = '100,25'

        $label_appProgPath = New-Object System.Windows.Forms.Label
        $label_appProgPath.Location = '10,60'
        $label_appProgPath.Size = '130,15'
        $label_appProgPath.Text = 'Path to PROG Policy'

        $textbox_appProgPath = New-Object System.Windows.Forms.TextBox
        $textbox_appProgPath.Location = '150,60'
        $textbox_appProgPath.Size = '170,25'

        $Radio_appBaseSW = New-Object System.Windows.Forms.RadioButton
        $Radio_appBaseSW.Location = '10,90'
        $Radio_appBaseSW.Size = '100,15'
        $Radio_appBaseSW.Text = "Software"
        $Radio_appBaseSW.DialogResult = [System.Windows.Forms.DialogResult]::SW

        $Radio_appBaseHW = New-Object System.Windows.Forms.RadioButton
        $Radio_appBaseHW.Location = '10,110'
        $Radio_appBaseHW.Size = '100,15'
        $Radio_appBaseHW.Text = "Hardware"
        $Radio_appBaseHW.DialogResult = [System.Windows.Forms.DialogResult]::HW

        $Button_appConfirm = New-Object System.Windows.Forms.Button
        $Button_appConfirm.Location = '220,95'
        $Button_appConfirm.Size = '100,30'
        $Button_appConfirm.Text = "Create"

        $form_appBase.Controls.Add($label_appFilename)
        $form_appBase.Controls.Add($Textbox_appFilename)
        $form_appBase.Controls.Add($label_appVersion)
        $form_appBase.Controls.Add($Textbox_appVersion)
        $form_appBase.Controls.Add($label_appProgPath)
        $form_appBase.Controls.Add($textbox_appProgPath)
        $form_appBase.Controls.Add($Radio_appBaseSW)
        $form_appBase.Controls.Add($Radio_appBaseHW)
        $form_appBase.Controls.Add($Button_appConfirm)

        $form_appBase.AcceptButton = $Button_appConfirm

        $dialogResultSHW = $form_appBase.ShowDialog()

        }

        $Button_appConfirm.Add_click(
        {

        if ($dialogResultSHW -eq "SW"){$appSHW = "SW"}

        elseif ($dialogResultSHW -eq "HW"){

        $appSHW = "HW"

        $appFilename = $Textbox_appFilename.Text
        $appVersion = $Textbox_appVersion.Text
        $appProgPath = $textbox_appProgPath.Text
        $appUNCPath = "\\zen\netlogon\applocker\Output + '\' + $appSHW + '-' + $appFilename + '-' $appVersion + '.' + 'xml' "

        Write-Host "$appFilename"
        Write-Host "$appVersion"
        Write-Host "$appProgPath"
        Write-Host "$appSHW"
        Write-Host "$appUNCPath"

        powershell.exe -file \\zen\netlogon\applocker\applockerwork.ps1 -application -in $appProgPath -out $appUNCPath 
        
        }
        }
        )

检查完所有内容后，我得到以下错误：

错误

有人能帮我找出为什么这个错误仍然存在吗？我尝试了很多我在WWW上发现的想法，但似乎没有什么效果。

Answer 1

首先，[System.Windows.Forms.DialogResult]枚举没有像"SW"或"HW"这样的值。

删除$Radio_appBaseSW.DialogResult = ...和$Radio_appBaseHW.DialogResult = ...行，因为作为评论的准则，RadioButtonClass没有这样的属性。

还将$dialogResultSHW = $form_appBase.ShowDialog()转换为[void]$form_appBase.ShowDialog()

然后，在您的$Button_appConfirm.Add_click({..})事件中，执行

$appSHW = if ($Radio_appBaseSW.Checked) { "SW" } elseif ($Radio_appBaseHW.Checked) {"HW"}

并使用$appSHW的值执行不同的操作，或者简单地执行

if ($Radio_appBaseSW.Checked) { 
    # perform action for choice Software
}
elseif ($Radio_appBaseHW.Checked) {
    perform a different action for choice Software
}
else {
    # no radiobutton was touched... Alert the user to select either the Software or the Hardware radio button
}

最后，当您完成$form_appBase.Dispose()的操作时，不要忘记从内存中删除表单。
