asp mvc textreader

Question

Hello, I am trying to use a textreader to retrieve data from a text file on a local machine. I have an upload routine to get the file for the reader to open.

When I run the application locally, it works fine. When I publish my application to my server, I am getting a Could not find a part of the path error. I assume this error has to do with permission in that the server cannot read from the local file system, but I don't know the proper way to remedy this.

do I set up the application to impersonate the user? I know I can't possibly set up each local users machine to allow the iusr account to access it.

Thanks for any thoughts.

UPDATE ** I ensured that network service is they user for the app pool. I also ensured that the networkService has access to the local folder that the application resides in. I am running IIS7, and when I test the site, I am getting the error -

The server is configured to use pass-through authentication with a built-in account to access the specified physical path. However, IIS Manager cannot verify whether the built-in account has access. Make sure that the application pool identity has Read access to the physical path. If this server is joined to a domain, and the application pool identity is NetworkService or LocalSystem, verify that <domain>\<computer_name>$ has Read access to the physical path. Then test these settings again

I have tried suggestions from various posts, including adding domain\servername$ to the folder to allow access, but nothing seems to work.

Any thoughts?

Answer 1

Assuming this is IIS 6.5 or higher, the application pool user must have the necessary permission. By default, this is Network Service, which likely does not.

Answer 2

I solved this issue by first saving the file to the server, and then accessing the server's local file -

savedFileName = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, Path.GetFileName(file.FileName));
                    file.SaveAs(savedFileName);
