Paypal 第一次尝试使用masspay时收到错误。

我试图创建一个对masspay的虚拟请求，但遇到了麻烦。masspay正在崩溃并退回这个

下面是我的代码。有人能告诉我我做错了什么吗： 将MassPayRequestItem设置为新的MassPayRequestItemType MassPayReqItem.Amount=新的基本计数类型 MassPayReqItem.Amount.currencyID=CurrencyCodeType.USD MassPayReqItem.Amount.Value=15.0 MassPayReqItem.Note=“测试批量付款” MassPayReqItem.ReceiverEmail=”user@email.com"

Dim MassPayRequestItem1作为新的MassPayRequestItemType
MassPayReqItem1.金额=新的基本金额类型
MassPayReqItem1.Amount.currencyID=CurrencyCodeType.USD
MassPayReqItem1.Amount.Value=5.0
MassPayReqItem1.Note=“测试批量付款1”
MassPayReqItem1.ReceiverEmail=”user1@email.com"
将massPayItemsArray（1）设置为MassPayRequestItemType
massPayItemsArray.SetValue（MassPayReqItem，0）
massPayItemsArray.SetValue（MassPayReqItem1，1）
将MassPayReqType设置为新的MassPayRequestType
MassPayReqType.MassPayItem=massPayItemsArray
MassPayReqType.Version=“51.0”
MassPayReqType.EmailSubject=“从我处批量付款”_
&Date.Now.ToLongTimeString
作为IAPIProfile=ProfileFactory.CreateSignatureApprofile（）的Dim配置文件
将调用者设置为新的com.paypal.sdk.services.CallerServices（）

profile.APISignature=“Alq1UN0gL5pSkR-311R7KRCKujzNfdsaasgasgsagsagcOvcvz-hn5Rd”
