using WebApplication2.Models;
namespace WebApplication2.Controllers
{
public class HomeController : Controller

_logger = logger;

public IActionResult Index()
{
return View();

public IActionResult SingleFile(IFormFile file)

[ResponseCache(Duration = 0, Location = ResponseCacheLocation.None, NoStore = true)]
public IActionResult Error()
