Question

就像我说的，我不能使用JsonConvert.SerializeObject（b）将字符串作为返回。

这就是我正在尝试的：

        BankAccount b = new BankAccount();
        b.Agencia = "0192";
        b.AgenciaDv = "0";
        b.Conta = "03245";
        b.ContaDv = "0";
        b.BankCode = "0341";
        b.DocumentNumber = "26268738888";
        b.LegalName = "API BANK ACCOUNT";
        b.Save();

        string json = JsonConvert.SerializeObject(b);

字符串json必须接收json对象，对吗？如何获取bankaccount b对象的json对象？

编辑：我没有任何例外。 BanckAccount是一个参考库的类。

    using System;
using Newtonsoft.Json;

namespace PagarMe
{
    public class BankAccount : Base.Model
    {
        protected override string Endpoint { get { return "/bank_accounts"; } }

        public string BankCode
        {
            get { return GetAttribute<string>("bank_code"); }
            set { SetAttribute("bank_code", value); }
        }

        public string Agencia
        {
            get { return GetAttribute<string>("agencia"); }
            set { SetAttribute("agencia", value); }
        }

        public string AgenciaDv
        {
            get { return GetAttribute<string>("agencia_dv"); }
            set { SetAttribute("agencia_dv", value); }
        }

        public string Conta
        {
            get { return GetAttribute<string>("conta"); }
            set { SetAttribute("conta", value); }
        }

        public string ContaDv
        {
            get { return GetAttribute<string>("conta_dv"); }
            set { SetAttribute("conta_dv", value); }
        }

        public DocumentType DocumentType
        {
            get { return GetAttribute<DocumentType>("document_type"); }
            set { SetAttribute("document_type", value); }
        }

        public string DocumentNumber
        {
            get { return GetAttribute<string>("document_number"); }
            set { SetAttribute("document_number", value); }
        }

        public string LegalName
        {
            get { return GetAttribute<string>("legal_name"); }
            set { SetAttribute("legal_name", value); }
        }

        public bool ChargeTransferFees
        {
            get { return GetAttribute<bool>("charge_transfer_fees"); }
            set { SetAttribute("charge_transfer_fees", value); }
        }

        public BankAccount()
            : this(null)
        {

        }

    public BankAccount(PagarMeService service)
            : base(service)
        {
        }
    }

我得到的“json”变量的结果是“{}”。我需要一个json对象来发一个帖子请求。我能做什么？

EDIT²： getAttribute：网络框架的标准方法。检索元素上命名属性的值。

SetAttribute：网络框架的标准方法。设置元素上命名属性的值。

Base.Model：

            var result = GetAttribute<object>("id");

            if (result == null)
                return null;

            return result.ToString();
        }
        set { SetAttribute("id", value); }
    }

认为错误就像配置一样。 Newtonsoft.Json需要在模型类中使用字段声明的特定配置吗？

我发现了问题。 BankAccount类在另一个解决方案中。引用了DLL，但是newtonsoft.json无法以这种方式序列化。

当我尝试在newtonsoft.json中使用Jsonserialize时，返回null到字符串
