Question

我使用newtonsoft JSON.NET库来序列化我无法修改的第三方库的对象。虽然它们具有值，但此对象的某些属性会序列化为空字符串。所以我想调用ToString只为特定类型的属性获取和序列化值。

namespace ThirdParty.Lib
{
    public class Info 
    {
       // When newtonsoft serialize a property of this type (CDataField) 
       // a get an empty string as value.
       public CDataField Name { get; set; }
       public CDataField Email { get; set; }
       public string IdNNumber {get; set;}
    }
}

var info = new ThirdParty.Lib.Info
{
   IdNumber = "001254810",
   Name = "John Doe",
   Email = "johndoe@gmail.com"
};
var jsonstring = Newtonsoft.Json.JsonConvert.SerializeObject(transactionModel)

//json string output
{ IdNumber: "001254810", Name: "", Email: "" }

最简单的方法是实现“克隆”类并对其进行序列化。像：

namespace MyNameSpace
{
    public class Info 
    {
        // When newtonsoft serialize a property of this type (CDataField) 
        // a get an empty string as value.
        public string Name { get; set; }
        public string Email { get; set; }
        public string IdNNumber {get; set;}

        Info(ThirdiParty.Lib.Info info)
        {
            Name = info.Name.ToString();
            Email = info.Email.ToString();
            IdNumber = info.IdNumber;
        }
    }
 }

var myinfo = new MyNameSpace.Info(
    new ThirdiParty.Lib.Info()
    {
        IdNumber = "001254810",
        Name = "John Doe",
        Email = "johndoe@gmail.com"
    }
);
