C# Newtonsoft.Json 序列化输出 json 字符串的常见格式, JsonConvert.SerializeObject 使用

    // Install-Package Newtonsoft.Json
    class Program
    {
        static void Main(string[] args)
        {
            // {"id":"123","name":"admin"}
            string jsonStr = JsonConvert.SerializeObject(new { id = "123", name = "admin" });

            Person person = new Person
            {
                Id = "123",
                Name = "admin",
            };

            // {"person":{"Id":"123","Name":"admin"}}
            string jsonStr2 = JsonConvert.SerializeObject(new { person });

            // {"Id":"123","Name":"admin"}
            string jsonStr3 = JsonConvert.SerializeObject(new Person
            {
                Id = "123",
                Name = "admin",
            });

            Console.WriteLine("Hello World!");
        }
    }

    public class Person
    {
        public string Id { get; set; }
        public string Name { get; set; }
    }
