Question

简介

我正在为我的演示项目使用paypal支付实现。当用户确认请求时，以json格式收到的响应和请求（正如大多数人所知）。

代码设置

行动“正在解析数据”

string str = JObject.Parse(executedPayment.ConvertToJson()).ToString(Newtonsoft.Json.Formatting.Indented);
var payerInfo = new JavaScriptSerializer().Deserialize<ResponseMappingObject.Payer_Info>(str);

foreach(var item in payerInfo)
{
string abc = payerInfo.first_name;
string abc2 = payerInfo.last_name;
}

为了舒适而添加的映射类

public class Payer_Info
        {
            public string email { get; set; }
            public string first_name { get; set; }
            public string last_name { get; set; }
            public string payer_id { get; set; }
        }

问题

通常，在“string str”中接收并解析成功并反序列化数据。但是构建时出错

foreach语句不能对类型的变量进行操作 'ResponseMappingObject.Payer_Info'因为 ResponseMappingObject.Payer_Info'不包含公共定义 'GetEnumerator'

问题

如果正确的反序列化json响应的方法如何解决这个问题？

我们可以在javascript中反序列化吗？如果它安全吗？

API会为您提供c# object（code source），使用其属性，无需反序列化。您不需要再次转换为JSON，JSON.parse，序列化，反序列化。例如：

std::cin

智能感知将有助于“发现”您需要的所有属性。

在c＃
