I'm working with firebase, and am fetching the data from the server with HttpWebRequest, I was able to retrieve this data as follows;

{"- L1OD7LjENM8ZHSpS7NE": {"Age": "18 years "," Name ":" vitor "," Telephone ":" 11 970705570 "}," - L1ODHPKmz_1zcCfpZwF ": {" Age ":" 10 years "," Name ":" joao "," Phone ":" 9898294792 "}," - L1ODMFC92yisdG4UxPU ": {" Age ":" 30 years "," Name ":" bruno "," Phone ":" 9898294792 "}}

Using this code below;

HttpWebRequest pesquisar = (HttpWebRequest)WebRequest.CreateHttp(URL);
pesquisar.ContentType = "application/json: charset=utf-8";
HttpWebResponse pesquisar1 = pesquisar.GetResponse() as HttpWebResponse;
using (Stream pesquisarStream = pesquisar1.GetResponseStream())
{
    StreamReader reader = new StreamReader(pesquisarStream, Encoding.UTF8);

            var text = reader.ReadToEnd();

            richTextBox1.Text = text;
}

I would like to receive this data, directly in a json file and create a list to manipulate both the data and the keys.

If anyone can help, thank you.

Run code only once .txt does not show old messages, takes only the last one and displays

If I may, I'd like to tell you a good way to solve this problem: Install the NewtonSoft package from Nuget: link

PM> Install-Package Newtonsoft.Json

Then, transform the received string into a dynamic list in order to work:

var listaDinamica = JsonConvert.DeserializeObject<JToken>(text);

After that, get the values of the elements, in order to remove the indices:

var lista = listaDinamica.Select(x => ((JProperty)x).Value.ToObject<Cliente>()).ToList();

At this point, if you need the Index, you can use the (JProperty) x) .Path instead of (JProperty) x) .Value. You could still create a dictionary to return key and value (careful with duplicate index).

After that point, I added a simple WriteLine to display on the console, but then you already have the list of objects you want. See the whole code below:

using System;
using Newtonsoft.Json;
using System.Linq;
using Newtonsoft.Json.Linq;

namespace ConsoleApp1
{
    class Program
    {
        public class Cliente
        {
            public string Idade { get; set; }
            public string Telefone { get; set; }
            public string Nome { get; set; }
        }

        static void Main(string[] args)
        {

            var text = "{\"-L1OD7LjENM8ZHSpS7NE\":{\"Idade\":\"18 anos\",\"Nome\":\"vitor\",\"Telefone\":\"11 970705570\"},\"-L1ODHPKmz_1zcCfpZwF\":{\"Idade\":\"10 anos\",\"Nome\":\"joao \",\"Telefone\":\"9898294792\"},\"-L1ODMFC92yisdG4UxPU\":{\"Idade\":\"30 anos\",\"Nome\":\"bruno\",\"Telefone\":\"9898294792\"}}";

            var listaDinamica = JsonConvert.DeserializeObject<JToken>(text);
            var lista = listaDinamica.Select(x => ((JProperty)x).Value.ToObject<Cliente>()).ToList();

            foreach (var item in lista)
            {
                Console.WriteLine(item.Nome);
            }
        }
    }
}
