给定 json 作为响应，但不确定如何解析它

Question

我正在使用此代码尝试从支付网关解析我的响应：

var responseMessage = client.PostAsJsonAsync("transaction", transData).Result;
var response = responseMessage.Content.ReadAsStringAsync().Result;
MessageBox.Show(response);
JavaScriptSerializer jsonSerializer = new JavaScriptSerializer();
var objCustomer = jsonSerializer.Deserialize<ReturnValues.RootObject>(response);

这是我正在尝试创建的类：

public class ReturnValues
{
public class Card
{
public string id { get; set; }
public string card_type { get; set; }
public string first_six { get; set; }
public string last_four { get; set; }
public string masked_card { get; set; }
public string expiration_date { get; set; }
public string status { get; set; }
public string auth_code { get; set; }
public string processor_response_code { get; set; }
public string processor_response_text { get; set; }
public string processor_type { get; set; }
public string processor_id { get; set; }
public string avs_response_code { get; set; }
public string cvv_response_code { get; set; }
public DateTime created_at { get; set; }
public DateTime updated_at { get; set; }
}
public class Response
{
public Card card { get; set; }
}
public class BillingAddress
{
public string first_name { get; set; }
public string last_name { get; set; }
public string company { get; set; }
public string address_line_1 { get; set; }
public string address_line_2 { get; set; }
public string city { get; set; }
public string state { get; set; }
public string postal_code { get; set; }
public string country { get; set; }
public string phone { get; set; }
public string fax { get; set; }
public string email { get; set; }
}
public class ShippingAddress
{
public string first_name { get; set; }
public string last_name { get; set; }
public string company { get; set; }
public string address_line_1 { get; set; }
public string address_line_2 { get; set; }
public string city { get; set; }
public string state { get; set; }
public string postal_code { get; set; }
public string country { get; set; }
public string phone { get; set; }
public string fax { get; set; }
public string email { get; set; }
}
public class Data
{
public string id { get; set; }
public string type { get; set; }
public int amount { get; set; }
public int tax_amount { get; set; }
public bool tax_exempt { get; set; }
public int shipping_amount { get; set; }
public int discount_amount { get; set; }
public string payment_adjustment_type { get; set; }
public int payment_adjustment_value { get; set; }
public string currency { get; set; }
public string description { get; set; }
public string order_id { get; set; }
public string po_number { get; set; }
public string ip_address { get; set; }
public bool email_receipt { get; set; }
public string email_address { get; set; }
public string payment_method { get; set; }
public Response response { get; set; }
public string status { get; set; }
public int response_code { get; set; }
public string customer_id { get; set; }
public BillingAddress billing_address { get; set; }
public ShippingAddress shipping_address { get; set; }
public DateTime created_at { get; set; }
public DateTime updated_at { get; set; }
}
public class RootObject
{
public string status { get; set; }
public string msg { get; set; }
public Data data { get; set; }
}
}

这是我得到的回应：

我收到此消息：

System.InvalidOperationException： '无法转换类型的对象 "System.String"键入"Test.ReturnValues+Response">

我不确定我做错了什么。我使用在线 json 转换器来上课。这似乎是正确的。

有什么建议吗？

我使用 json2csharp.com 来生成C#类，它提出了一些不同的东西。

public class ReturnValues
{
public class Card
{
public string id { get; set; }
public string card_type { get; set; }
public string first_six { get; set; }

public object settled_at { get; set; }
}
public class RootObject
{
public string status { get; set; }
public string msg { get; set; }
public Data data { get; set; }
}
}

不过它似乎有效。我做了一个快速比较，有很多差异。可能值得一试。

使用jsoup它是一个免费的框架，它可以轻松地将文档解析为json格式

`list<Element> news;
Document doc = Jsoup.connect("https://en.wikipedia.org/").get();
log(doc.title());
Elements newsHeadlines = doc.select("#mp-itn b a");
for (Element headline : news) {
log("%snt%s", 
headline.attr("title"), headline.absUrl("href"));
}`
