C# generates a multidimensional array of Json

Today I specially sorted out how to generate the json array, because I used to be lazy when I needed to use the json array, using i.ToString();

Take a three-dimensional array as an example:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using Microsoft.Office.Interop.Excel;
using System.Diagnostics;
using System.Text.RegularExpressions;
using LitJson;

namespace TestPath
{
    class Program
    {


        static void Main(string[] args)
        {
            int[,,] a = new int[2, 2, 2];
            a[0, 0, 0] = 2;
            a[0, 0, 1] = 3;
            a[0, 1, 0] = 2;
            a[0, 1, 1] = 4;
            a[1, 0, 0] = 2;
            a[1, 0, 1] = 5;
            a[1, 1, 0] = 2;
            a[1, 1, 1] = 6;

            //声明一个Json对象
            JsonData data = new JsonData();

            for (int i = 0; i < a.GetLength(0); ++i)
            {
                //往Json对象里添加索引键i
                data.Add(i);
                //将data[i]初始化为新的JsonData对象，否则会nullReference
                data[i] = new JsonData();
                
                for (int j = 0; j < a.GetLength(1); ++j)
                {
                    //同理，这时候需要往data[i]里添加j的索引键
                    data[i].Add(j);
                    data[i][j] = new JsonData();
                    for (int k = 0; k < a.GetLength(2); ++k)
                    {
                        data[i][j].Add(k);
                        data[i][j][k] = a[i, j, k];
                    }
                }
            }

            string json = data.ToJson();
            //json：[[[2,3],[2,4]],[[2,5],[2,6]]]
            byte[] bytes = System.Text.Encoding.UTF8.GetBytes(json);
            File.WriteAllBytes(@"E:\jjj.json", bytes);

        }
    }
}

//Ignore unnecessary using, because this project is usually used for testing.

 

Each time you need to add a new integer index key, you must use the .Add(int) method to add it, so that you can continue to initialize data[i], because data[i] exists.

If it is an index key of a string, you can directly add data[string key] to add key-value pairs.
