Simple json editor using c#

I have created a sample project to read json file, edit and save into another file using c# and Newtonsoft.Json library. If anyone want this kind of implementation, you can download project and continue. I have added the sample json file with the project into my Github repository.

Github repository

I have json file format like below.

{
"tasks": [{
"AccountName": "testaccount",
"AccountKey": "0de5edbc-6a02-4450-a139-33d4e760a257",
"ContainerName": "1234",
"RootPath": "/",
"DaysOfHistoryToKeep": 10
}, {
"AccountName": "test2",
"AccountKey": "f15c414b-734a-4a4e-b1a6-eb0794df4e46",
"ContainerName": "2345",
"RootPath": "/",
"DaysOfHistoryToKeep": 15
}]
}

According to that json structure, i am going to build my object structure like below.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace JsonEditor
{
    public class Task
    {
        public string AccountName { get; set; }
        public string AccountKey { get; set; }
        public string ContainerName { get; set; }
        public string RootPath { get; set; }
        public int DaysOfHistoryToKeep { get; set; }
    }
}

And I have Tasks class which contains list of Task classes.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace JsonEditor
{
    public class Tasks
    {
        public List<Task> tasks { get; set; }
    }
}

This is how program going to read the json file and convert into list and bind into grid.

Stream myStream = null;
            OpenFileDialog theDialog = new OpenFileDialog();
            theDialog.Title = "Open Text File";
            theDialog.Filter = "JSON files|*.json";
            theDialog.InitialDirectory = @"C:\";
            if (theDialog.ShowDialog() == DialogResult.OK)
            {
                try
                {
                    if (theDialog.FileName.Trim() != string.Empty)
                    {
                        using (StreamReader r = new StreamReader(theDialog.FileName))
                        {
                            string json = r.ReadToEnd();
                            Tasks items = JsonConvert.DeserializeObject(json);
                            dgTasks.DataSource = items.tasks;
                        }
                    }
                }
                catch (Exception ex)
                {
                    MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
                }
            }

And convert grid data into json file.

Tasks tasks = new Tasks();
            tasks.tasks = (List)dgTasks.DataSource;
            
            SaveFileDialog saveFileDialog1 = new SaveFileDialog();
            saveFileDialog1.InitialDirectory = @"C:\";
            saveFileDialog1.Filter = "JSON Image|*.json";
            saveFileDialog1.Title = "Save a JSON File";

            if (saveFileDialog1.ShowDialog() == DialogResult.OK)
            {
                File.WriteAllText(saveFileDialog1.FileName, JsonConvert.SerializeObject(tasks));
            }

Please download the project and use it in your projects. You have to add exception handling into this project.
