Build configuration from multiple json files

Question

I have a bunch of json files which all have the same structure.

Filestructure by samples:

{"Item1":{"Prop1"=1}}
{"Item2":{"Prop1"=2}}

I want these read into a .net app configuration as a dictionary (The root of each file is dictionary key, eg "Item1").(The app is using IHost and DI)

Perhaps by something like AddOptions<Dictionary<string, ItemClass>>()

I don't know how to get going, anyone may give me a push in the right direction?

Hi, @EuroEager2008

This code might help you!
Please let me know if there's anything else I can assist you with.

{
  "MyConfig": {
    "Item1": { "Prop1": 1 },
    "Item2": { "Prop1": 2 }
  }
}

using System.Collections.Generic;
using System.IO;
using Newtonsoft.Json;

public class ItemClass
{
	public int Prop1 { get; set; }
}

public class MyConfig
{
	public Dictionary<string, ItemClass> Config { get; set; }
}

//Startup.cs or Program.cs
// ..
services.Configure<MyConfig>(Configuration.GetSection("MyConfig"));
// ..

public class MyController : Controller
{
	private readonly MyConfig _myConfig;
	public MyController(IOptions<MyConfig> myConfig)
	{
		_myConfig = myConfig.Value;
	}

	public IActionResult Index()
	{
		var item1 = _myConfig.Config["Item1"];
		return View();
	}
}

In order for this code to work, you need to provide valid JSON files.
As @Thomas Wycichowski said: You will need to adjust

from
{"Item1":{"Prop1"=1}}

to
{"Item1":{"Prop1":1}}

Have a nice day,
