Question

有没有办法按JSON数组中的值索引进行搜索。例如，有没有办法做某事......

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ExcelDna.Integration;
using System.Threading.Tasks;
using System.Diagnostics;    

namespace BTPRTD
{
    class Program
    {
        static void Main(string[] args)
        {
        }
    }

    public static class MyFunctions
    {
        public static MouseData MData;

        [ExcelFunction(Description = "My first .NET function")]
        public static string SayHello(string name)
        {
            //Debugger.Launch();
            MData = new MouseData ();

            Task.Factory.StartNew(() =>
            {            
                ExcelAsyncUtil.QueueAsMacro(() =>
                {
                    KeepWritingData();
                });
            }); 
            return "Hello " + name;  
        }

        public static void KeepWritingData()
        {
            var refB1 = new ExcelReference(0, 0, 1, 1, "Sheet1");
            string dataTxt = "";
            for (int i = 0; i < 100; i++)
            {
                try
                {
                    MouseData .CurrentPriceData CPD = MData.GetCurrentPriceNT("White mouse");
                    dataTxt = CPD.AsString();
                }
                catch (Exception)
                {
                    dataTxt = "Data Unavailable";
                }

                refB1.SetValue("Ding: " + i + " " + dataTxt);
                System.Threading.Thread.Sleep(1000);
            }
        }
    }
}

这样它将返回索引为＆＃34; s＆＃34;的所有行。在JSON专栏＆＃34; myJSONArr＆＃34;是3还是4？
