私はアプリケーションを開発し、リモートDB接続を使用してローカルで正常に動作しましたが、すべてのポストバックイベントでライブサーバーに配置すると、次の例外が発生します。

この行をweb.configの下に追加しましたが、うまくいきました。

    <machineKey validationKey="ED69AB3D81E3E1CFBE24D3910DDCD3DAFD0919466CD7D442D45E33BCEF2A72DB26CFDDF390D843EF4AB6A2A4C7DA6F23327C0482EA1CF67AF41B188F495D7112" decryptionKey="B114854371A664138153F7A0605108B09E1E871CC112C7873AD2F58C158D11FC" validation="SHA1" decryption="AES" />
