Json.NET ：用方括号序列化

Question

我怎样才能为我的项目设置 header：

{"geometricShapes":[{"circle": "1","triangle": "2","square": "3"},{"circle": "1","triangle": "2","square": "3"}]}

我目前的成绩：

[
  {
    "circle": "1",
    "triangle": "2",
    "square": "3"
  },
  {
    "circle": "1",
    "triangle": "2",
    "square": "3"
  }
]

我使用的方法：

Deserialize to add the elements to the model object then make a list with 2 copies of it (geometricShapesList)

            string jsonString = '{"circle": "1","triangle": "2","square": "3"}'
            Model.GeometricShapes geometricShapes = JsonConvert.DeserializeObject<GeometricShapes>(jsonString);
            List<GeometricShapes> geometricShapesList = new List<GeometricShapes >();
            geometricShapesList.Add(geometricShapes);
            geometricShapesList.Add(geometricShapes);
            string jsonStringUpdated = JsonConvert.SerializeObject(geometricShapesList, Formatting.Indented);
            Console.WriteLine(jsonStringUpdated);

您可以使用类来解决您的问题。我建议您遵循以下解决方案。您可以使用 Json to C# 从 json 字符串生成类。

using Newtonsoft.Json;
using System;
using System.Collections.Generic;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            string jsonString = "{\"circle\": \"1\",\"triangle\": \"2\",\"square\": \"3\"}";

            Root root = new Root();
            GeometricShape geometricShape = JsonConvert.DeserializeObject<GeometricShape>(jsonString);
            List<GeometricShape> geometricShapesList = new List<GeometricShape>();
            geometricShapesList.Add(geometricShape);
            geometricShapesList.Add(geometricShape);

            root.geometricShapes = geometricShapesList;

            string jsonStringUpdated = JsonConvert.SerializeObject(root, Formatting.Indented);
            Console.WriteLine(jsonStringUpdated);
        }

        public class GeometricShape
        {
            public string circle { get; set; }
            public string triangle { get; set; }
            public string square { get; set; }
        }

        public class Root
        {
            public List<GeometricShape> geometricShapes { get; set; }
        }
    }
}

输出：

{
  "geometricShapes": [
    {
      "circle": "1",
      "triangle": "2",
      "square": "3"
    },
    {
      "circle": "1",
      "triangle": "2",
      "square": "3"
    }
  ]
}
