私はPowershellで私の最初のフォームに取り組んでおり、XAML（https://foxdeploy.com/2015/04/10/part-i-creating-powershell-guis-in-minutes-using-visual-studio-a-new-hope/のコードを基にしています）を使っています。XAMLフォーム+キャンセルボタンの応答
フォームは素晴らしいので、データ検証に取り組んでいます。私はWhileループを通してすべてのフィールドを必須にしようとしていますが、私はそこから抜け出せません。以下のコードをどのようにして、誰かが[キャンセル]ボタンをクリックしたときにループを終了する必要があることを理解させるにはどうすればよいですか？私は$ WPFcancelButton.IsPressedをチェックしようとしましたが、更新されていないようです。
ありがとうございました。
