如何在c#中成功从Stripe Events of Charge中获取客户ID

我想要来自 StripeEvents 的 CustomerID。我从 strip webhook 检索了 json。我已经完成了一些代码，但自从 customerID 得到

NULL

               var bodyStream = new StreamReader(HttpContext.Current.Request.InputStream);
                bodyStream.BaseStream.Seek(0, SeekOrigin.Begin);
                var json = bodyStream.ReadToEnd();

                var stripeEvent = EventUtility.ParseEvent(json);

                // Handle the event
                if (stripeEvent.Type == Events.ChargeSucceeded)
                {
                    var CustomerID = stripeEvent.Data.Object as Customer;
                }

对于 ChargeSucceeded 你会得到一个 Charge 对象，而不是 Customer，所以我会这样做：

if (stripeEvent.Type == Events.ChargeSucceeded)
{
    var charge = stripeEvent.Data.Object as Charge;
    var CustomerID = charge.CustomerId
}
