本文實例講述了C#實現將類的內容寫成JSON格式字符串的方法。分享給大家供大家參考。具體如下：

本例中建立了Person類，賦值后將類中內容寫入到字符串中

運行本代碼需要添加引用動態庫Newtonsoft.Json

程序代碼：

				?

									using System;

									using System.Collections.Generic;

									using System.Linq;

									using System.Text;

									using System.Threading.Tasks;

									//需要引用 Newtonsoft.Json.dll

									using Newtonsoft.Json;

									namespace JsonTest

									{

									 class Program

									 {

									  /// <summary>

									  /// 人員類

									  /// </summary>

									  public class Person

									  {

									   public string name; //姓名

									   public int age; //年齡

									   public bool sex_is_male; //性別

									   public struct Partner //伙伴

									   {

									    public string partner_name; //伙伴姓名

									    public int partner_age; //伙伴年齡

									    public bool partner_sex_is_male; //伙伴性別

									   }

									   public Partner partner;

									   public string[] achievement; //成就

									  }

									  static void Main(string[] args)

									  {

									   //設置一個Person類

									   Person p = new Person();

									   p.name = "Tsybius";

									   p.age = 23;

									   p.sex_is_male = true;

									   p.partner.partner_name = "Galatea";

									   p.partner.partner_age = 21;

									   p.partner.partner_sex_is_male = false;

									   p.achievement = new string[] { "ach1", "ach2", "ach3" };

									   //直接輸出

									   Console.WriteLine("Formatting.None:");

									   string json1 = JsonConvert.SerializeObject(p);

									   Console.WriteLine(json1 + "\n");

									   //縮進輸出

									   Console.WriteLine("Formatting.Indented:");

									   string json2 = JsonConvert.SerializeObject(p, Formatting.Indented);

									   Console.WriteLine(json2 + "\n");

									   Console.ReadLine();

									  }

									 }

									}
