Files under wwwroot path is not accessible

I have a functionality in my web application that let the users download some help documents by clicking on the document name. Recently I made a change in my project, I kept all the pdf files in my wwwroot folder instead of keeping them on some directory on the server. I kept them in the following hierarchy wwwroot > Assets > ConnectHelpDocuments. Now after deploying the application for some reason when I click on the file It says "Access to the path 'C:\Webs\Engage\API\wwwroot\Assets\ConnectHelpDocuments\xxxxx.pdf' is denied". It works fine on my localhost. Here's the code snippet that tries to read from the wwwroot and then send that as a file.

private const string ResourceDocument = @".\wwwroot\Assets\ConnectHelpDocuments\";

        [HttpGet("DownloadDocument/{fileName}")]
        [TypeFilter(typeof(AsyncUserActionFilter))]
        [System.Web.Mvc.ValidateInput(true)]
        public async Task<IActionResult> DownloadDocument(string fileName)
        {
            try
            {
                string filePath = Path.Combine(ResourceDocument, fileName);
                if (!System.IO.File.Exists(filePath))
                    return NotFound();
                var memory = new MemoryStream();
                using (var stream = new FileStream(filePath, FileMode.Open))
                {
                    await stream.CopyToAsync(memory);
                }
                memory.Position = 0;
                return File(memory, GetContentType(filePath), fileName);
            }
            catch (Exception ex)
            {
                this.logger.LogError(ex.Message);
                return BadRequest(ex.Message);
            }
        }

I am also attaching the screenshot of the project folder structure which shows the folders

enter image description here

Can anyone help me identify the reason? Is there any settings on the IIS that I need to tweak ? I don't have much access here otherwise I would have pasted the IIS settings as well.

Did you find a solution yet?

IWebHostEnvironment
WebRootPath

You can find the path of your file using the WebRootPath of IWebHostEnvironment. You will need to include this in your program/startup file. For example:

private readonly IWebHostEnvironment _environment;

public Startup
(
   IWebHostEnvironment environment
)
{
   _environment = environment;
}

And:

public class TestService : ITestService
{

   public static IWebHostEnvironment _environment;

   public TestService
   (
      IWebHostEnvironment environment
   )
   {
      _environment = environment;
   }

   private MemoryStream Attachment()
   {

      MemoryStream stream = new();

       try
       {

        string path = _environment.WebRootPath;
        path += "/Assets/ConnectHelpDocuments/Testfile.pdf";

        byte[] testByte = File.ReadAllBytes(path);

        stream = new(testByte, false);

      }
      catch (Exception exceptionTest)
      {
         Error_General(exceptionTest);
      }

      return stream;
   }
}

Also: please check whether your file properties is set to content. Otherwise it's not included in the publish.

Hope this helps.

Kind regards.
