Visual Studio PowerShell 将附件从 Outlook 拖放到列表框

Question

i have got the drag and drop working on my Windows Form. i can drop items from my desktop or any folder but if i try to Drag an attachment straight from Outlook it won't do any thing. do i need to add extra PowerShell commands int my current code

######################################## This is For Drag And Drop 

  $listBox1_DragOver = [System.Windows.Forms.DragEventHandler]{
    if ($_.Data.GetDataPresent([Windows.Forms.DataFormats]::FileDrop)) 
    {
        $_.Effect = 'Copy'
    }
    Else
    {
        $_.Effect = 'None'
    }
    }

    $listBox1_DragDrop = [System.Windows.Forms.DragEventHandler]{
        foreach ($filename in $_.Data.GetData([Windows.Forms.DataFormats]::FileDrop)) 
        {
            $listBox1.Items.Add($filename)
        }

        }

        ### Add events to form ###

    $listBox1.Add_DragOver($listBox1_DragOver)
    $listBox1.Add_DragDrop($listBox1_DragDrop)
    #$form.Add_FormClosed($form_FormClosed)

        #### Show form and return result ###
    $dialogResult = $Form12.ShowDialog()
    if ($dialogResult -eq [System.Windows.Forms.DialogResult]::OK)
     {
      $Form12.SuspendLayout()
       [array]$items =  $listbox1.Items| sort -CaseSensitive
       if ($items.Count -gt 1){
       $items
       }
       ELSE
       {
       [string]$items[0]
       }
      $Form12.Close() | out-null
     }

After lot's of research i came across the code below, to summarise what it does.

it will let you drag and drop files out of Outlook, it will then copy and paste that into a folder which then gives you the path and file name. it is pretty cool so if anyone else is stuck here is my working script and how i implemented it to my form

######################################## This is For Drag And Drop 
$Listbox1.AllowDrop = $true 
$Listbox1.Add_DragDrop({
    if ($_.Data.GetDataPresent([Windows.Forms.DataFormats]::FileDrop)) { 
        foreach ($FileName in $_.Data.GetData([Windows.Forms.DataFormats]::FileDrop)) {
            Copy-Item -Path $FileName -Destination $textbox6.text -Force
            $Listbox1.Items.Add($FileName)

        }
    }
    else 
    {
        $Outlook = New-Object -ComObject Outlook.Application;
        $Selection = $Outlook.ActiveExplorer().Selection                                                                       
        foreach ($Item in $Selection) {
            foreach ($Attachment in $Item.Attachments) {
                Write-Verbose $Attachment.FileName
                $Name = Join-Path -Path $textbox6.text-ChildPath $Attachment.FileName
                $Attachment.SaveAsFile($Name)


            }         
        }

    }
})
$Listbox1.Add_DragEnter({$_.Effect = [Windows.Forms.DragDropEffects]::Copy})
$Form12.Controls.Add($Listbox1) 

# Activate the form     

[void] $Form12.ShowDialog()

i had to change my form a little by adding an Input Folder Button & Textbox6 to show the text of the folder that has been selected this is important as the Script above needs a directory to save the files to, please see code below.

###################################### Get Folder Using Folder Browser and output text into textbox 
$button4_Click = {

$folderBrowserDialog3=New-Object System.Windows.Forms.FolderBrowserDialog
[void]$folderBrowserDialog3.ShowDialog()
$folderBrowserDialog3.SelectedPath
$textBox6.Text = $folderBrowserDialog3.SelectedPath
}

$button6_Click = {

$folderBrowserDialog1=New-Object System.Windows.Forms.FolderBrowserDialog
[void]$folderBrowserDialog1.ShowDialog()
$folderBrowserDialog1.SelectedPath
$textBox2.Text = $folderBrowserDialog1.SelectedPath
}

$button7_Click = {

$folderBrowserDialog2=New-Object System.Windows.Forms.FolderBrowserDialog
[void]$folderBrowserDialog2.ShowDialog()
$folderBrowserDialog2.SelectedPath
$textBox3.Text = $folderBrowserDialog2.SelectedPath
}

after i got that to work the thing that bugged me the most was i couldn't see the files in the listbox so i added a button to do exactly that please see code below

###################################### Shows Files In ListBox 1
    $button5_Click = {
    #$textbox8.Text = ""
    $listBox1.Items.Clear()
    $items = Get-ChildItem $textbox6.Text
    ForEach($item in $items){
    $listBox1.Items.Add($item.FullName)
       }
    }

as you can see i have added $listbox1.Items.Clear() this will enable you to keep clicking the show files button without it duplicating the path and file in the listbox

the final result of my Form has come out great please see my image layout below, if anyone needs help to get it working on your own Form please comment and i will do my best to help.
