我不能序列化一个包含多个部分的JSON？

Question

我有以下的json，我想序列化以在一个POST请求中发送。

 {
      "Details
        ": {
        "title": "Mr",
        "firstName": "Jimmy",
        "lastName": "Jameson",
        "dateOfBirth": "20.01.1994",

      },
      "meterreading": {
        "mnrr": "10234567891",
        "Longmeterread ": "12345",
        "Shortmeterread ": "23456",
        "Medtmeterread ": "34567"
      }
        },
      "otherdata": {
        "xyz": "somedata",
        "lmnop ": "more",
        "qrst ": "even more",
        "uvwz ": "last one"
      }



  I have created the following class to represent it in Visual Studio:
  {
    public class MainObjectModel
    {
        public Details Details { get; set; }
        public meterreading meterreading { get; set; }
        public otherdata otherdata { get; set; }
    }

    public class Details
    {
        public string _title = "Mr";
        public string _firstName = "Jimmy";
        public string _lastName = "Jameson";
        public string _dateOfBirth = "20.01.1994";


    }


    public class meterreading
    {
        public string _mnrr = "10234567891";
        public string _Longmeterread = "12345";
        public string _Shortmeterread = "23456";
        public string _Medtmeterread = "34567";
    }

    public class otherdata
    {
        public string xyz = "somedata";
        public string lmnop = "more";
        public string qrst = "even more";
        public string uvwz = "last one";

    }

}

当我实例化MainObjectModel然后序列化时，每个类都返回为null？我试着通过删除MainObjectModel部分来简化类，但它只序列化了第一部分，而且它没有部分的标题？我如何在VS中安排该类以上述格式返回json？先谢谢你的帮助。

Answer 1

的 "details" 是破碎的。

# wrong
"Details
        ": {

# better
"Details": {
