我需要反序列化来自FastBill API的JSON响应，（我正在使用JSON .NET），我创建了C＃类，它将“保存”从API响应中检索到的数据，问题是服务器响应不正确，如下所示：

（反斜杠似乎仅出现在调试器中，所以这不是问题。）
如果我完全这样保留响应，则运行时不会给出任何错误，但是JsonConvert.DeserializeObject不会在C＃类的“字段”中返回响应中的数据，否则，如果我删除了REQUEST和RESPONSE标头，只留下了INVOICES项，似乎“可行”，但是现在编译器出现了一个新错误：
'解析值{时遇到意外字符。路径'VAT_ITEMS'，第1行，位置373。'

反序列化
JSON.GET_INVOICE GetInvoiceStruct = JsonConvert.DeserializeObject<JSON.GET_INVOICE>(_response);
我真的不明白如何成功反序列化响应。
答案 0 :(得分：4)
您已成功为要反序列化的主要对象准备了模型。 现在，您还需要为集合建模其他模型：
当前，您已将它们建模为string，但它们根本不是字符串，它们是复杂的对象。
我将为您提供VatItem的示例，然后您可以自己完成其余的工作。
创建VatItem模型，即：
public class VatItem
{
//Did not used decimal type because I don't know how JSON.NET handles it
public double VAT_PERCENT { get; set; }
public double COMPLETE_NET { get; set; }
public double VAT_VALUE { get; set; }
}
为json响应的这一部分建模：
\"VAT_PERCENT\":\"19.00\",
\"COMPLETE_NET\":22.66,
\"VAT_VALUE\":4.3061344545
然后GET_INVOICE中的更改将您的VAT_ITEMS集合建模为：
public IList<VatItem> VAT_ITEMS { get; set; }
在此示例后面加上两个其他集合以完成映射。
