我正在為我的客戶開發(fā)定制的付款方式插件。我是 Nopcommerce 插件開發(fā)的初學(xué)者，這是我的插件目錄結(jié)構(gòu)：代碼這是我的CODBookingPaymentProcessor.cspublic class CODBookingPaymentProcessor : BasePlugin, IPaymentMethod{    #region Ctor    public CODBookingPaymentProcessor()    {    }    #endregion    #region Methods    public bool SupportCapture => false;    public bool SupportPartiallyRefund => false;    public bool SupportRefund => false;    public bool SupportVoid => false;    public RecurringPaymentType RecurringPaymentType => RecurringPaymentType.NotSupported;    public PaymentMethodType PaymentMethodType => PaymentMethodType.Standard;    public bool SkipPaymentInfo => false;    public string PaymentMethodDescription => "Pay booking and extras before order placing.";    public CancelRecurringPaymentResult CancelRecurringPayment(CancelRecurringPaymentRequest cancelPaymentRequest)    {        return new CancelRecurringPaymentResult();    }    public bool CanRePostProcessPayment(Order order)    {        if (order == null)            throw new ArgumentNullException(nameof(order));        //it's not a redirection payment method. So we always return false        return false;    }    public CapturePaymentResult Capture(CapturePaymentRequest capturePaymentRequest)    {        return new CapturePaymentResult { Errors = new[] { "Capture method not supported" } };    }    public decimal GetAdditionalHandlingFee(IList<ShoppingCartItem> cart)    {        return 0;    }    public ProcessPaymentRequest GetPaymentInfo(IFormCollection form)    {        return new ProcessPaymentRequest();    }    public string GetPublicViewComponentName()    {        return "CODBooking";    }    public bool HidePaymentMethod(IList<ShoppingCartItem> cart)    {        return false;    }    public void PostProcessPayment(PostProcessPaymentRequest postProcessPaymentRequest)    {    }
