Able to download file locally but not from Azure

Question

I have the following action method (as suggested by Vague).

public IActionResult Document(string name)
{
  try
  {
    var filepath = $"wwwroot/{name}";
    byte[] fileBytes = System.IO.File.ReadAllBytes(filepath);
    return File(fileBytes, "application/x-msdownload", name);
  }
  catch (Exception exception) { return Ok(exception.Message) }
}

When I execute in locally, I get the files as expected. However, when I upload to Azure, I get the error that the path is wrong.

Could not find a part of the path 'D:\Windows\system32\wwwroot\doc02.doc'.

Assuming that it's about the path being incorrect, I've tried all combinations of prefixing with "~", ".", "./" etc. that I could think of. After a few hours, I realize that it's an ostrich (you can try and try but it ain't gonna fly).

What can I be missing?

I put files to "always upload", of course. And I verified by entering the URL to said files (they are in the root directory, right next to logo.gif).

How about storing whole path in db? or saving them in location like ``D:\AppFiles\`` if that's possible. Btw You're sure you want to store ``docs`` in a static files folder? — Joelty, Feb 15 '19 at 07:42
@Joelty Nope, I'm sure I don't. But it seems like a lot of work to protect them better. Unless you've got a suggestion on how to... — Konrad Viltersten, Feb 15 '19 at 15:43
I'm saving file somewhere on disk (outside the app), saving its path in db and identifying it with an Id (Guid) e.g ``localhost:5000/download/{guid}`` which then verifies permissions and all business logic, then reaches file from disk with path from db. — Joelty, Feb 18 '19 at 08:04
