    var files = Request.Form.Files;     
    foreach (var file in files)
    {       
        if (file == null || file.Length == 0)
        {
            continue;
        }
        var filePath = Path.Combine(uploadsRootFolder, queryModel.Name  + files[0].FileName);
        using (var fileStream = new FileStream(filePath, FileMode.Create))
        {
            await file.CopyToAsync(fileStream).ConfigureAwait(false);
        }
    }
    return Json("ok");

工作正常...

string fileName = file_name+".pdf";

           string files = System.IO.Path.Combine("pdf/") + fileName;
            if (!System.IO.File.Exists(files))
            {
                return RedirectToAction("index", new { message = "File Not Found" });

            }
            else
            {

                byte[] fileBytes = System.IO.File.ReadAllBytes(files);
                return File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Octet, files);

            }

在asp.net核心中访问被拒绝的文件
