10401订单总数无效ASP.NET C#

我正在使用ASP.NET（Web表单）和msdn的WingtipToys教程编写一个商店应用程序

我有一个问题，当我使用贝宝按钮。我有一个错误：

10401
Transaction refused because of an invalid argument. See additional error messages for details.
Order total is invalid.

这是代码的一部分，我认为有问题：

    // Get the Shopping Cart Products
    using (Shop.Logic.ShoppingCartActions myCartOrders = new Shop.Logic.ShoppingCartActions())
    {
        List<ElementKoszyka> myOrderList = myCartOrders.GetCartItems();

        for (int i = 0; i < myOrderList.Count; i++)
        {
            encoder["L_PAYMENTREQUEST_0_NAME" + i] = myOrderList[i].Produkt.nazwa_produkt.ToString();
           // string tmp = Math.Round(myOrderList[i].Produkt.cena, 2).ToString();
           // encoder["L_PAYMENTREQUEST_0_AMT" + i] = Math.Round(myOrderList[i].Produkt.cena, 2).ToString();
            encoder["L_PAYMENTREQUEST_0_AMT" + i] = "22.50";
            encoder["L_PAYMENTREQUEST_0_QTY" + i] = myOrderList[i].ilosc.ToString();
        }
    }

    string pStrrequestforNvp = encoder.Encode();
    string pStresponsenvp = HttpCall(pStrrequestforNvp);

    NVPCodec decoder = new NVPCodec();
    decoder.Decode(pStresponsenvp);

    string strAck = decoder["ACK"].ToLower();
    if (strAck != null && (strAck == "success" || strAck == "successwithwarning"))

总订单已永久分配（22.50），但仍有问题

有什么提示吗？

价格在

encoder["L_PAYMENTREQUEST_0_AMT" + i] = "22.50";

也许应该是这样

encoder["L_PAYMENTREQUEST_0_AMT" + i] = myOrderList[i].Produkt.nazwa_price.ToString();

---

价格是在

encoder["L_PAYMENTREQUEST_0_AMT" + i] = "22.50";

也许应该是这样

encoder["L_PAYMENTREQUEST_0_AMT" + i] = myOrderList[i].Produkt.nazwa_price.ToString();

---

好的，问题解决了。我必须在不同的班级把金额改成小数

---

所以贝宝订单的正确格式是：“xx.xx”

好的，问题解决了。我必须在不同的班级把金额改成小数

---

因此，paypal订单的正确格式是：“xx.xx”

如果您的计算机使用十进制komma，那么您应该将分配更改为：

encoder["L_PAYMENTREQUEST_0_AMT" + i] = (myOrderList[i].Produkt.nazwa_price.ToString()).Replace(",",".");

---

如果您的计算机使用十进制komma，则您应将分配更改为：

encoder["L_PAYMENTREQUEST_0_AMT" + i] = (myOrderList[i].Produkt.nazwa_price.ToString()).Replace(",",".");

我也有同样的问题。原因是波兰的十进制格式不同。 要查看要更改的行，请在下面的代码中查找//注释：
