Json嵌套数组文件开发实例

一、开发思路说明

通过对需求分析，确定了该项目需要处理两层嵌套的JSON数据结构。为此，打算使用C#和Newtonsoft.json库来实现内容的序列化和反序列化。具体实现逻辑如下：

以下是实现步骤详细说明：

二、具体实现步骤

2.1 创建基础类：MapInfo.cs

using System;using System.Collections.Generic;namespace JsonDemo{    public class MapInfo    {        public string mapName { get; set; }        public string type { get; set; }        public string count { get; set; }        public string url { get; set; }        public string progress { get; set; }        public string waitCount { get; set; }    }}

2.2 创建第一层嵌套类：TestInfo.cs

using System.Collections.Generic;using Newtonsoft.Json;namespace JsonDemo{    public class TestInfo    {        public string XMText { get; set; }        public string XMTYPE { get; set; }        public string XMCount { get; set; }        public List
   
     mapInfos { get; set; }        public TestInfo()        {            mapInfos = new List
    
     ();        }    }}
    
   

2.3 实现对象并生成JSON文件

以下是完整的程序实现，用于生成嵌套的JSON文件：

using JsonDemo;using Newtonsoft.Json;using System;using System.Collections.Generic;using System.IO;using System.Linq;namespace JsonHelper{    public class Program    {        public static void Main(string[] args)        {            List
   
     testInfos = new List
    
     ();                        // 创建说明信息            TestInfo testInfo1 = new TestInfo();            testInfo1.XMText = "综合交通1";            testInfo1.XMTYPE = "01";            testInfo1.XMCount = "108";                        TestInfo testInfo2 = new TestInfo();            testInfo2.XMText = "综合交通2";            testInfo2.XMTYPE = "02";            testInfo2.XMCount = "109";                        // 添加第一个信息            List
     
       mapInfos1 = new List
      
       ();            MapInfo mapInfo1_1 = new MapInfo();            mapInfo1_1.mapName = "市重点交通";            mapInfo1_1.type = "32";            mapInfo1_1.count = "20";            mapInfo1_1.url = "../ProjectManage/Pagessilding/Zhonghejiaotong/Zhonghetra_list.aspx?type=0101";            mapInfo1_1.progress = "52.61";            mapInfo1_1.waitCount = "27";                        MapInfo mapInfo1_2 = new MapInfo();            mapInfo1_2.mapName = "支路网建设";            mapInfo1_2.type = "32";            mapInfo1_2.count = "20";            mapInfo1_2.url = "../ProjectManage/Pagessilding/Zhonghejiaotong/Zhonghetra_list.aspx?type=0111";            mapInfo1_2.progress = "52.61";            mapInfo1_2.waitCount = "27";                        mapInfos1.Add(mapInfo1_1);            mapInfos1.Add(mapInfo1_2);            testInfo1.mapInfos = mapInfos1;                        // 添加第二个信息            List
       
         mapInfos2 = new List
        
         (); MapInfo mapInfo2_1 = new MapInfo(); mapInfo2_1.mapName = "市重点交通2"; mapInfo2_1.type = "32"; mapInfo2_1.count = "20"; mapInfo2_1.url = "../ProjectManage/Pagessilding/Zhonghejiaotong/Zhonghetra_list.aspx?type=1101"; mapInfo2_1.progress = "52.61"; mapInfo2_1.waitCount = "30"; MapInfo mapInfo2_2 = new MapInfo(); mapInfo2_2.mapName = "支路网建设2"; mapInfo2_2.type = "32"; mapInfo2_2.count = "20"; mapInfo2_2.url = "../ProjectManage/Pagessilding/Zhonghejiaotong/Zhonghetra_list.aspx?type=1111"; mapInfo2_2.progress = "52.61"; mapInfo2_2.waitCount = "30"; mapInfos2.Add(mapInfo2_1); mapInfos2.Add(mapInfo2_2); testInfo2.mapInfos = mapInfos2; // 加入集合 testInfos.Add(testInfo1); testInfos.Add(testInfo2); // 序列化为JSON string jsonContent = Newtonsoft.Json.JsonConvert.SerializeObject(testInfos); // 保存文件 bool success = SaveFile(@"e:\Zhonghejiaotong.json", jsonContent); Console.WriteLine("保存情况：" + success); } private static bool SaveFile(string path, string contents) { bool success = false; using (FileStream fs = new FileStream(path, FileMode.CreateNew, FileAccess.ReadWrite, FileShare.ReadWrite)) { using (StreamWriter sw = new StreamWriter(fs, Encoding.UTF8)) { sw.WriteLine(contents); success = true; } } return success; } }}
