當我在 Powershell ISE 中運行以下代碼時，一切正常，但是當我從 Powershell Shell 運行它時，我收到了很多關于圖示的錯誤。
[System.Reflection.Assembly]::LoadWithPartialName("System.windows.forms") |Out-Null
$foldername = New-Object System.Windows.Forms.FolderBrowserDialog
$foldername.Description = "Select a folder"
$foldername.rootfolder = "MyComputer"
$foldername.SelectedPath = $initialDirectory
if($foldername.ShowDialog() -eq "OK")
{
$folder = $foldername.SelectedPath
}
$folder
錯誤示例：

阿道頓，
請注意，ISE 具有自動加載的內容，而 CMD 版本沒有并且必須由程式員加載。下面修改后的代碼（閱讀代碼中的注釋）適用于 PowerShell 5.1.19041.1237 的 ISE 和 CMD 版本
Add-Type -AssemblyName System.windows.forms
$Folder = @() #Set up blank array so = works!
$TermMsg = {
[Windows.Forms.MessageBox]::Show($Message,
"$Title",
[Windows.Forms.MessageBoxButtons]::OK ,
[Windows.Forms.MessageBoxIcon]::Information) | Out-Null}
If ($host.Name -eq 'ConsoleHost' -or
$host.Name -eq 'Visual Studio Code Host') {
try{ <# ------------------------------------------------
| Check that the proper assemblies are loaded |
| Required for PS Console and Visual Code, while |
| only Systems.Windows.Forms needed for PSISE! |

$ATArgs = @{AssemblyName = "PresentationCore",
"PresentationFramework",
"WindowsBase"
ErrorAction = 'Stop'}
Add-Type @ATArgs
}
catch {
$Title = "Program Terminated:"
$Message =
"Failed to load Windows Presentation Framework"
" and/or other assemblies required for this program!"
& $TermMsg
Exit
}
} #End If ($host.Name...
$foldername = New-Object System.Windows.Forms.FolderBrowserDialog
