如何将 Program.CS 中的变量传递给 .NET Core 2.1 中的 Controller？

Question

I will apologize in advance that I am a complete novice with .NET so please bear with me. My goal is to simply be able to pass variables from my Program class to a controller in my setup.

Program.cs

using System;
using System.Collections.Generic;
using System.IO;

namespace EJ2FileManagerService
{
    public class Program
    {
        public static void Main(string[] args)
        {
            CreateWebHostBuilder(args).Run();
        }
        public static IWebHost CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                     .ConfigureAppConfiguration((hostingContext, config) =>
                     {
                         var test = "results"; 
                     })
                .UseStartup<Startup>()
                .Build();
    }
}

I want to be able to consume the variable test in my TestController class. It is located under Controllers/TestController.cs.

TestController.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Authorization;

namespace EJ2FileManagerServices.Controllers
{
    [Route("api/[controller]")]
    
    public class TestController : Controller
    {
    
    // WANT TO READ TEST VARIABLE HERE

        // GET api/values
        [HttpGet]
        public IEnumerable<string> Get()
        {
            return new string[] { "value1", "value2" };
        }
        // GET api/values/5
        [HttpGet("{id}")]
        public string Get(int id)
        {
            return "value";
        }
    }
}

This was simply just user error -- the first comment was correct I just needed to do my calls and actions inside the controller versus inside of Program.cs.

Thanks!
