Question

我有自定义结帐方法。我也有自定义送货方式。

我已将所有自定义代码翻录出来并直接复制并粘贴Sitefinity文档中的自定义送货方式文件：

http://www.sitefinity.com/documentation/documentationarticles/documentationarticles/developers-guide/sitefinity-essentials/modules/ecommerce/creating-a-custom-shipping-carrier-provider

和

http://www.sitefinity.com/documentation/documentationarticles/shipping-provider-model

根据此文档，我可以在电子商务后端创建新的送货方式，并选择我的自定义送货方式。

我有以下代码将我的结帐状态送货方式ID设置为我的自定义送货方式ID。我的购物车订单也一样：

CheckoutState checkoutState = new CheckoutState()
{
    ...
    ShippingMethodId = shippingManager.GetShippingMethods().FirstOrDefault(s => s.Name == "custom-shipping").Id,
    ShippingMethodName = shippingManager.GetShippingMethods().FirstOrDefault(s => s.Name == "custom-shipping").Name,
    ...
}

和

cartOrder.ShippingMethodId = shippingManager.GetShippingMethods().FirstOrDefault(s => s.Name == "custom-shipping").Id;

工作正常，花花公子。获取送货方式。此送货方式包含我在遵循文档时定义的自定义送货运单ID。我添加了2个运输服务设置。我也可以使用以下方法查询它们：

var shippingCarrierInfo = shippingManager.GetShippingCarrierSetting("custom-shipping");
List<ShippingServiceSettings> services = shippingManager.GetShippingServiceSettings().Where(
                                                x => x.ShippingCarrierName == shippingCarrierInfo.Name &&
                                                x.IsActive == true).ToList();

我没有空或空或任何东西。所有信息均符合预期。

我通过这样做来获取我的服务的运费回复：

List<IShippingResponse> shippingResponses = processShipping.GetApplicableShippingMethods(checkoutState, cartOrder).ToList();

这会抛出一条可爱的通用错误消息：

空参考例外 {＆＃34;对象引用未设置为对象的实例。＆＃34;}

当然，我无法看到他们所说的是空的。但是我得到了一个错误的方法的堆栈跟踪。

我失去了我需要做的事情。这是一个来回的支持票，现在约3.5个星期。愤怒的客户和我需要找到一种方法来实现这一点。就像我直接从文档中复制和粘贴说的那样。有人有这方面的经验吗？
