File upload to wwwroot folder in ASP.NET Core

Question

Why is my following codes sometimes work, but sometimes it does't work?

 private bool UploadFile(IFormFile ufile, string fname)
 {
     if (ufile.Length > 0)
     {
          string fullpath = Path.Combine(_env.WebRootPath, fname);
          using (var fileStream = new FileStream(fullpath, FileMode.Create))
          {
               ufile.CopyToAsync(fileStream);
          }
          return true;
     }
     return false;
 }

The code did managed to save the picture to a folder which I created under wwwroot, but the picture is not appearing, and even in Visual Studio too.

Is there a way to solve it?

Thanks.

Even when I open up the file explorer of the folder that is storing the pictures, the picture is like is there but not showing any image.

Try as follows. File will be uploaded to images folder under wwwroot folder.

private async Task<bool> UploadFile(IFormFile ufile)
{
     if (ufile != null && ufile.Length > 0)
     {
          var fileName = Path.GetFileName(ufile.FileName);
          var filePath = Path.Combine(Directory.GetCurrentDirectory(), @"wwwroot\images", fileName);
          using (var fileStream = new FileStream(filePath, FileMode.Create))
          {
              await ufile.CopyToAsync(fileStream);
          }
          return true;
      }
      return false;
}

Had same problem with dot net core, here's what I did:

-Make virtual directory

-Map it to that folder path (inside wwwroot)

-Make your fullpath equals to this VD ; absolute path (can keep it in config file)

-Give write permissions for this folder to iisuser

allow accessing to static files, just add this line in you startup.cs file under Configure method:

app.UseStaticFiles();
