【问题描述】：

我正在添加 20.00 的项目并将订单总额设置为 22.00

 paymentDetails.OrderTotal = new PayPalSandboxWS.BasicAmountType()
     {
         currencyID = ConvertProgramCurrencyToPayPalSandbox(currency),
         Value = "22.00"
     };

并将运费总额设置为 2.00

 paymentDetails.ShippingTotal = new PayPalSandboxWS.BasicAmountType()
     {
         currencyID = ConvertProgramCurrencyToPayPalSandbox(currency),
         Value = "2.00"
     };

但我收到此错误：The totals of the cart item amounts do not match order amounts.

请帮忙

我的情况完全一样，想知道您是否找到了解决方案？在文档中找不到任何关于它的内容：cms.paypal.com/us/cgi-bin/…
你是否也有：SetExpressCheckoutRequestDetailsType sdt = new SetExpressCheckoutRequestDetailsType(); sdt.ShippingMethod = ShippingServiceCodeType.CustomCode; sdt.ShippingMethodSpecified = true;

【解决方案1】：

您错过了设置ItemTotal 值！这导致了这个错误：

double itemTot  = 20.0;
double tot      = 22.0;
double shipping = 2.0;
string desc     = "";
var paymentDetailsItemTypes = new List<PaymentDetailsItemType>();

PaymentDetailsType pdt = new PaymentDetailsType()
{        
    OrderDescription = desc,
    OrderTotal = new BasicAmountType()
    {
        currencyID = CurrencyCodeType.EUR,
        Value = tot.ToString("0.00", System.Globalization.CultureInfo.InvariantCulture)
    },
    PaymentDetailsItem = paymentDetailsItemTypes.ToArray(),
    ShippingTotal = new BasicAmountType()
    {
        currencyID = CurrencyCodeType.EUR,
        Value = shipping.ToString("0.00", System.Globalization.CultureInfo.InvariantCulture)
    },
    ItemTotal = new BasicAmountType()
    {
        currencyID = CurrencyCodeType.EUR,
        Value = itemTot.ToString("0.00", System.Globalization.CultureInfo.InvariantCulture)
    }
};
