C#如何向<dynamic>数组添加成员(JSON)

List<dynamic> jsonArray = new List<dynamic>();

dynamic jsonMember = new ExpandoObject();

jsonMember.key1 = "value1";
jsonMember.key2 = "value2";

jsonArray.Add(jsonMember);

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

namespace JsonArrayExample
{
    class Program
    {
        static void Main(string[] args)
        {
            List<dynamic> jsonArray = new List<dynamic>();

            dynamic jsonMember = new ExpandoObject();
            jsonMember.key1 = "value1";
            jsonMember.key2 = "value2";

            jsonArray.Add(jsonMember);

            string json = JsonConvert.SerializeObject(jsonArray);
            Console.WriteLine(json);
        }
    }
}
