C#超精簡的Json工具

本文轉載自查看原文 2020-06-13 15:24 703

　　自制了一個C#使用的Json工具類，沒有什么奇奇怪怪的引用庫，.Net4.0以上可直接運行，適合對json解析有需求但又不需要很重視的項目使用

　話不多說，直接上代碼

  1 using System.Collections.Generic;
  2 using System.Web.Script.Serialization;
  3 public class JsonHelper
  4 {
  5     public static string Serialize<T>(T t)
  6     {
  7         JavaScriptSerializer js = new JavaScriptSerializer();
  8         return js.Serialize(t);
  9     }
 10     public static T Deserialize<T>(string Json)
 11     {
 12         JavaScriptSerializer js = new JavaScriptSerializer();
 13         return js.Deserialize<T>(Json);
 14     }
 15     public static JsonBuilder CreateJsonObjectBuilder()
 16     {
 17         JsonBuilder builder = new JsonBuilder();
 18         return builder;
 19     }
 20     public static JsonBuilder CreateJsonArrayBuilder()
 21     {
 22         JsonBuilder builder = new JsonBuilder();
 23         return builder.ToArray();
 24     }
 25 }
 26 public class JsonBuilder

下面是測試，受Unity中DoTween動畫插件的啟發，設計了這種鏈式開火車的API，用起來可是十分優雅

1 JsonBuilder json = JsonHelper.CreateJsonObjectBuilder();
2 JsonBuilder array = JsonHelper.CreateJsonArrayBuilder();
3 array.AddItem(new JsonBuilder().SetProperty("item1","item1__value"));
4 array.AddItem(new JsonBuilder().SetProperty("item2","item2__value"));
5 json = json.SetProperty("name", "Zack").SetProperty("blog","cnblogs").SetProperty("obj", (new JsonBuilder().SetProperty("value", 1000))).SetProperty("array", array);
6 Console.WriteLine(json.ToJson());
7 Console.ReadLine();

結果：

{"name":"Zack","blog":"cnblogs","obj":{"value":1000},"array":[{"item1":"item1__value"},{"item2":"item2__value"}]}

當然咯，以上工具類只是我個人用的，還沒有在正式項目中驗證過，若有什么錯誤的地方歡迎指正

以上。
