C# 序列化大小写 序列化对象为大小写 JsonConvert.SerializeObject

关于C#序列化Json对象

框架：.Net

插件：Newtonsoft.Json

最近有人问我序列化对象还区分大小写？ 我当时心想我都是通过Bejson 格式化然后转换为C# 类然后直接复制。

没有关心过序列化成什么大小写。因为这样的话可以保持一致。

直到有人问我才自己研究了一下。

如下：

using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.Text;
using System.Threading.Tasks;
using System.Xml;
using Newtonsoft.Json.Serialization;
using Formatting = Newtonsoft.Json.Formatting;
using static System.Net.Mime.MediaTypeNames;
using System.Text.Json;
using System.Xml.Linq;
using static System.Threading.Thread;
using static 序列化.Program;

namespace 序列化
{
    internal class Program
    {
        private static void Main()
        {
            //定义匿名对象
            var user = new { name = "john", age = 19 };
            var user1 = new { NAME = "JOHN", AGE = 19 };
            var user2 = new { Name = "john", Age = 19 };
            var user3 = new { namE = "john", agE = 19 };
            var user4 = new { naMe = "john", aGe = 19 };

            Action(user);
            Action(user1);
            Action(user2);
            Action(user3);
            Action(user4);
            Console.WriteLine("分割");
            Action1(user);
            Action1(user1);
            Action1(user2);
            Action1(user3);
            Action1(user4);
            Console.WriteLine("分割");
            var person = new Person { Age = 10, Name = "john" };
            Action2(person);
            var person1 = new Person1 { Age = 10, Name = "john" };
            Action2(person1);

            Console.ReadKey();
        }

        public static void Action(dynamic obj)
        {
            var serializerSettings = new JsonSerializerSettings
            {
                // 设置为驼峰命名
                ContractResolver = new CamelCasePropertyNamesContractResolver()
            };
            //序列化成字符串
            var userStr = JsonConvert.SerializeObject(obj, Formatting.None, serializerSettings);

            //输出字符串
            Console.WriteLine($"方法一{userStr}");
        }

        public static void Action1(dynamic obj)
        {
            //ToTitleCase 会把头一个字母大写  弊端:如果你的变量值为英文则也会变成大写
            var monstrous = CurrentThread.CurrentCulture.TextInfo.ToTitleCase(JsonConvert.SerializeObject(obj));

            //ToUpper 将所有文本变成大写
            var monstrous1 = CurrentThread.CurrentCulture.TextInfo.ToUpper(JsonConvert.SerializeObject(obj));

            //ToUpper 将所有文本变成大写
            var monstrous2 = CurrentThread.CurrentCulture.TextInfo.ToLower(JsonConvert.SerializeObject(obj));
            Console.WriteLine($"方法二{monstrous}{monstrous1}{monstrous2}");
        }
        public static void Action2(Person obj)
        {
            //Formatting.Indented 使用子类型对象
            var json = JsonConvert.SerializeObject(obj, Formatting.Indented);
            Console.WriteLine($"方法三{json}");
        }
        public static void Action2(Person1 obj)
        {
            var json = JsonConvert.SerializeObject(obj, Formatting.Indented);
            Console.WriteLine($"方法三{json}");
        }
        [DataContract]
        public class Person
        {
            [DataMember(Name = "AGE")]
            public int Age { get; set; }

            [DataMember(Name = "NAME")]
            public string Name { get; set; }
        }
        [DataContract]
        public class Person1
        {
            [DataMember(Name = "aGe")]
            public int Age { get; set; }

            [DataMember(Name = "NaME")]
            public string Name { get; set; }
        }
    }

}

以上就是我自己写的一个Demo来搞序列化对象成为我想要的对象大小写。

输出如下：

 我个人认为方法三才是真正能实现我的需求，其他两种都有相对应的弊端。

 也可能方法用法不对。也希望大神能多多指教。
